Web Usability
Web usability refers to the user-friendliness of websites. Websites should be effective and intuitive for visitors to use so that the website's objectives can be better achieved.
Even though there is a lot of talk today about interaction design and, according to ISO standards, web usability (during use) is only understood as part of the user experience (before, during and after use), there is still a lot you can do for your website.
Some measures are rather easy to implement in your editorial work, some require more perseverance and should gradually improve the LMU Klinikum website for which you are responsible. We would like to recommend the following measures to you.
5 measures to improve web usability
1 - Successful texts for websites
How do website visitors read on the screen?
Numerous studies have shown that website visitors only "scan", i.e. skim, texts on the screen.
To ensure that your content is perceived in the best possible way, it is necessary to structure your website in such a way that visitors find as much content as possible as quickly as possible and, above all, the content they are looking for.
- Ask yourself what your visitors want from you. Give it to them!
- Change your perspective: The overly detailed presentation of your internal structures (including the associated "abbreviations") is difficult for visitors to understand or uninteresting.
- Get a clear picture of your target group. Always think of people, not institutions (e.g. "researchers", not "universities").
- Make your goals clear and record them in writing. This way you can check later whether you have achieved them.
- "The bait should taste good to the fish, not the angler".
1. screen reading is tedious
Reading on a screen is difficult and is around a quarter slower than on paper. The eyes tire more quickly as the resolution on the monitor is lower. The viewing area is smaller than with print: individual passages have to be maneuvered into the field of vision.
Reading is also more strenuous due to a static and uncomfortable reading posture.
2. text length is difficult to estimate
On the web, there is no "sense of place" as websites cannot be scrolled through quickly, making it difficult to assess how much text/content is on the website. Compared to a book: scrolling, thick/thin, number of pages!
Problem for the website visitor: Is it worth starting to read?
2. text lengths are difficult to estimate
Research into screen reading has produced the following results, which you as a web editor should bear in mind. Users do not read on the web, they scan. The following figures illustrate this:
- less than 20 % read word for word
- over 80% scan, skim the page and search for keywords
- On average, users only read around 20% of the text
- About half of less than 100 words are read
- An additional 4.4 seconds per additional 100 words = a maximum of 18 additional words
- On average, the visitor spends approx. 20 to 25 seconds "basic time" on the page, 10-15 seconds of which is spent reading
- Scanning takes place in an F-shape (twice horizontally over the first two paragraphs, then vertically along the left edge of the page). Lines are usually not read to the end.
- Website visitors are benefit-oriented. If they do not find the desired benefit, they quickly lose interest and leave the website. You should therefore regularly add relevant information.
- Websites do not allow a view of the entire website. They lack the "sense of place" that print media convey. Therefore, provide orientation through your navigation (menu structure)!
These facts apply to searching and browsing, as well as to narrow single-columns, wide single-columns and double-columns.
Vertical scrolling is done quickly and easily, whereas horizontal scrolling is almost never done. Attention decreases towards the bottom and around 80% of user time is spent "above the fold". Users spend approx. 70% of their time on the left half of the screen and approx. 30% on the right half. Only 1% of the content is paid attention to when scrolling horizontally.
Photos must be informative and genuine, because users ignore photos if they are only intended to "spice up" the page or are purely decorative (feel-good images). Users pay attention to graphics and photos if they contain relevant content.
Structure text, divide it into portions and offer it in F-form
Headings
Content must be to the point, no riddles, no complicated jokes, no allusions and no irony. Don't promise anything that the text doesn't deliver and write from the perspective of the target audience.
Advice
- Save words: e.g. delete articles
- No subordinate clauses
- No abbreviations
- No long words: use hyphens to make long words visually manageable
- Few punctuation marks
- (never: period, exclamation mark; rarely: dash, comma; good: colon)
- Verbs as active as possible and in the present tense
- Key words up front (helpful: colon)
Teaser
A teaser provides an incentive to read and condenses information from the text. Users read the first few words and want to find out more if they are caught up in them. Teaser texts should be short, rule of thumb: a maximum of three sentences.
The font size of the teaser should stand out from the text so that teasers are more likely to be read. Bold lead-ins generate a high level of attention for 5-10 seconds and therefore have an influence on whether a text is read.
Running text
Organize your text visually and break it down into small chunks. Research shows that short sections attract twice as much attention as long ones.
Advertising style is perceived as annoying.
Advice
- Make each page understandable on its own; you never know where the user is coming from
- Repetition of headline/teaser for orientation: "I've come to the right place"
- Meaningful headlines and subheadings (at least one per screen page)
- Start the page with a summary (What is it about? What are the benefits?)
- Text sections with only one topic or sub-aspect each
- Main content in the first two paragraphs
- Short paragraphs are considered more intensively than longer ones (one paragraph, one train of thought, white space to separate the paragraphs)
- Enumerations with bullet points
- Never use justified text
- NEVER write IN CAPITAL LETTERS or in italics
- Bold keywords and place them at the beginning of paragraphs
- Short sentences
- One thought, one sentence
Links
- Embedded links
Disadvantage: disrupt the flow of reading in the text. The user asks himself the question: Read on or click?
Therefore, do not place links too early in the text, but introduce the topic first, otherwise the user will leave (too) quickly. - Links outside the text:
Advantages: makes sense in terms of reading psychology, thoughtful selection of links, links can be moderated and commented on
Disadvantage: links are no longer context-related
1. simple texts
- one thought, one sentence
- Prefer active, name the "perpetrator"
- Avoiding wide sentence brackets and broken verbs
- Use common words, explain foreign words
- Avoid tapeworm words
- Human language instead of computer language
2. structure text
- Offer information in a comprehensible order
- Sentences must relate to each other in a meaningful way
- Clarify the train of thought with linking words
- Message pyramid (central information, supporting facts, interesting details, context & background)
3. brevity is the spice of life
- Delete filler words
- Avoid stretched verbs
- shorten superfluous adjectives
- shorten unnecessary details
- omit unnecessary temporal references
4. offer additional incentives
- stimulating words
- stimulating questions
- direct address
- inversion: changing parts of sentences for emphasis
- Use concrete examples
- Making numbers vivid
Please make sure to offer your central websites in German and English. In this way, you can ensure that you are also seen internationally.
Tip: If your website needs to be updated frequently, you may not always have the capacity to maintain it in two languages. In this case, you should therefore translate a basic offering with permanently relevant content.
2 - Targeted use of images on the web
The rapidly growing photo-sharing platforms Instagram and Pinterest clearly show the importance that images already have on the web and will have in the future. Images are also strong traffic generators if they rank in the top positions in Google Image Search.
"A picture is worth a thousand words" is a metaphor for the added value of images compared to pure text:
- complicated issues can often be explained very simply.
- Images leave a stronger impression on the viewer than extensive text.
- Websites look livelier, more attractive and convert better.
- Users are better addressed and can experience your website, not just browse through it.
How do you achieve positive emotions?
Tip 1 - Emotions are the key
Many people act for emotional reasons. Therefore, the selection of strong, emotional images is important to put the visitor in the right mood. A positive image evokes positive emotions.
Give visitors a good feeling of happiness or desire and your customers will be in a positive mood and respond to your offers. Working with positive emotions is very effective.
Tip 2 - The user is king
Your potential new customers don't care about you, they only care about themselves. You should therefore appeal to the customer's ego factor. They should feel comfortable and your offers should be perfectly tailored to the needs of your users. This will encourage more people to come to you.
Tip 3 - Pay attention to quality
The pictures should be appropriate to the occasion:
- simple reporting: self-shot, technically sound picture.
- Documentation, e.g. of a large-scale research project: commission a professional photographer.
Tip 4 - Reflect the message of the text
The message of an image must match the message of the text. Images often contain hidden messages or create different associations depending on the viewer. It is important to be sensitive here and to allow an image to work together with the text, including the headline, for a moment. The contradiction between text and image often has a subconscious effect and can cancel out or reverse the effect of a text statement.
Suitable images
- good resolution
- bright, clear images that evoke emotions and associations
- people in action
- activities
- exciting content, e.g. machines that arouse interest
- unusual perspectives or cropping
- authentic images with a visible connection to the LMU Clinic
- close-ups
Unsuitable images
- blurred, shaky images
- poorly recognizable content (unless it is an artistically created element of tension)
- passport photos
- People in re-enacted standard situations (handshakes, roundtables etc.)
- PR images from unidentified sources
- Crowd in the distance
3 - Maximum accessibility of websites (accessibility)
The aim of an accessible website is to provide all users with fast, uncomplicated access to the desired information, regardless of the devices used to call up the pages (graphic browsers, screen readers, PDAs, printers, etc.).
Accessibility therefore does not only mean programming that is suitable for the disabled or blind. It also means that access to a site and its content is optimized so that all users benefit.
Barrier-free optimization concerns four essential points:
- Perceivability of the content
- Comprehensibility of the content
- usability of the website
- technological robustness
In 2002, the Federal Barrier-free Information Technology Ordinance (BITV) was created, which became state law in 2007: all websites of public bodies must be designed to be barrier-free.
There is a tool for determining accessibility that you can use to test whether your website is accessible.
How do you achieve maximum accessibility?
Optimal accessibility
The website www.klinikum.uni-muenchen.de and all subpages should achieve optimum accessibility through
- structured organization of the content
- basic separation of layout and content
- Markup languages and style sheets must be used in accordance with their specifications.
- Alt and title texts for images and links
- Explaining abbreviations
- Alternative texts for audio and video content
- adjustable font sizes
- Tables that are used exclusively for the preparation of structured data (tables are never used for layout purposes!)
- Semantically correct page structure: Formatting (headings etc.) must not be used for aesthetic purposes
- Use of clearly distinguishable colors
The implementation of a website according to BITV is not easy, but it is worth it: The websites must be understandable for all people with disabilities and the content must work not only on the screen, but also via reading programs (screen readers), Braille outputs, etc.
What are tags?
PDF tags reflect the structure of a document. They indicate which text is a heading, which text parts form a paragraph or whether a text represents a bookmark. As tags map the document structure, the exact reading direction can be specified and navigation in a document can be improved.
Tags help people to understand the structure and content of a document when they read a document using a screen reader, for example. If the tags are missing in a document, content is read out in the wrong order or not at all.
As tags are generated from the structure of the source document, the document itself must be well structured. Therefore, always work with style sheets for headings and paragraphs in word processing programs, give each image an alternative text and mark hyperlinks in a text document accordingly. Any requirement that is already fulfilled by the source document does not need to be edited in the PDF document afterwards.
Alternative texts for graphics / images
The graphics / images must be provided with alternative texts. The alternative texts should be equivalents of the image/graphic in text form and fulfill the same function as the image.
It is therefore essential to provide a description when including graphics / images.
Structural elements for headings
Headings must be correctly labeled with the structural elements h1 (heading 1) to h6 (heading 6).
Tables with headings
Ensure that headings in tables are marked up accordingly.
For tables, you must mark up the heading cells (heading rows or columns).
Meaningful link texts
Make sure that link texts also explain something about the link target outside the context of your text! They should be meaningful regardless of the context:
If you need to use short words such as "more"; "here"; "more information" as links, be sure to enter an associated title attribute. In the menu under Insert, select Insert link. In the window that appears under Advanced, enter the title attribute describing the link.
Simple words
Use clear and simple language for the content of a page. Web content, including Word and PDF documents, should not cause any difficulties even for inexperienced users (bear in mind the target group). Foreign words or technical terms can become a hindrance for the user. Their use can exclude potential users.
Simple sentences
The comprehensibility of content means that texts must be easy to read and understand.
- Ensure that sentences are as short as possible and that simple sentence constructions are used.
- Write in a short, precise, concise style. Key messages must be quickly recognizable and simply formulated. A clear structure helps to maintain an overview.
- Avoid foreign words and incomprehensible technical terms. If such words are used, they should be explained in detail.
- The use of simple sentences is beneficial for all users, but especially for users with learning disabilities.
- Avoid ambiguity.
Highlight words / sections in other languages
This is a note in case you need to mark up language markups manually at times. Screen readers and other assistive technologies have different language libraries for different languages. A German sentence spoken or read aloud with English pronunciation could become unintelligible.
Individual foreign language words also need to be marked up. When content authors mark the natural language changes in a document, language generators and Braille devices can automatically switch to the new language, making the document more accessible to multilingual users.
Make abbreviations recognizable
This is a note in case you use abbreviations and therefore need to mark them up!
Please use the <abbr> tag to make abbreviations and acronyms recognizable. Use the icon in the TinyMCE editor for this. The tag designates an enclosed text as an acronym or abbreviation. The tag is only supported by the newer generation of browsers and is simply ignored by most older browsers.
For example: Keyword accessibility according to <abbr title='Barrierefreie Informationstechnologie-Verordnung'>BITV</abbr>
Meaningful link texts
If it is not possible to display the graphic (e.g. text browser), the text entered as alt text is displayed to the user instead of the image. If the image is also a link, the alternative text of the image is displayed instead of the image and the title of the link is displayed as the link text.
Make sure that you do not use any links on your pages whose destination does not (or no longer) exist. It is therefore best to link internally within the clinic as much as possible (not absolutely externally).
Do not use links in the main content where the target does not correspond to the announcement (alternative text, link itself).
Also make sure that the names of menu items correspond to the link target
Steps of video creation
- Recording with video camera
- Transfer video to computer (large data size)
- Open video editing program
- Adobe Premiere Pro
- Camtasia
- Movie Maker -> Windows
- iVideo -> Macintosh
- possibly cut video as desired
- save as mp4, optimal size 800 x 600 px
- if the video is still too large, edit it with a conversion program:
- Any Video Converter
- Miro Video Converter
Making video accessible
People who are blind, visually impaired, deaf or hard of hearing require assistance to understand multimedia website content. Blind, visually impaired and people with motor impairments are also unable to find or hit the play button, for example. It must therefore be possible to play the video without a mouse, i.e. using only the keyboard.
For all these reasons, it is necessary to specially prepare videos on the hospital's website. This includes
- Subtitles
- Audio description
- Alternative control elements
Subtitles
Subtitles for videos are primarily aimed at the target group of deaf and hard of hearing people. Foreign-language viewers or viewers who watch the videos without sound or are in noisy surroundings also benefit. Subtitles describe acoustic elements in a video (e.g. spoken or sung words, the horn of a car or animal noises) and thus offer a legible alternative to sound. The aim is to be able to understand the content even without sound.
Audio description
Audio description is aimed at the target group of blind and visually impaired people. It only describes what is visually contained in a video (e.g. facial expressions, gestures and appearance of the characters, descriptions of movements and the surroundings). The aim is to be able to imagine the visuals as well as the sound.
Effort for the creation
Subtitles
The effort required to integrate subtitles into a video is relatively low. Especially if a kind of electronic script is available. Then the spoken language can be used for subtitling with copy & paste. If the texts first have to be written electronically, the time required increases accordingly. On average, it can be assumed that subtitling will take around 3 to 4 times the time of the video.
Audio description
There is no electronic script for audio description. The scenes must therefore be described afterwards. The descriptions must be embedded between the pauses in the actors' speech.
A good audio description is heavily dependent on the knowledge of the scriptwriter.
The time required for audio description is difficult to estimate. In general, it can be said that this is significantly higher than for subtitling.
4 - Animating use of multimedia
Animating multimedia is the presentation of content via various channels. One example is a sound film, as this serves both the eye and the ear.
The presence of different interaction options also plays an important role, e.g. control of playback parameters. This fills screens with life, sober texts and columns of figures become more meaningful through graphics, animations, video sequences and acoustic information. Interaction with the computer becomes an information experience.
The combined use of several media should help to achieve existing goals, such as enhancing customer service, strengthening customer loyalty or accelerating evaluation and decision-making processes, more easily and present the company in an attractive way.
The advantage of using different media is that it makes it easier for the viewer to absorb content, as they take in the information with different sensory organs. The use of images and sound makes the transfer of information more effective.
Which media should you use?
Visual effects, such as videos, are the best tools for attracting the attention of visitors more quickly and immediately arousing their interest. Videos add dynamism and atmosphere to a website and help to better convey the company's core messages. They enable emotions and the right mood to be created, thus creating an individual brand identity. They are an important element for content transmission.
Use of videos
- positively influence user experience through interactive experiences and invite them to explore a page further and deeper.
- are a powerful tool to keep customers on the website longer and with great interest.
- add value to products/services; show products/services in realistic usage scenarios and build enthusiasm for new products.
- at best remain in the visitor's memory, as the visual experience can be extremely impressive.
Before you get started and shoot an atmospheric video, however, you should first ask yourself how relevant the video is in relation to the information on the website or the products. Can the video amplify the message of the website or trigger a certain feeling? Or does it perhaps distract too much from the actual content or is it even annoying?
Important!
Headings must be correctly labeled with the structural elements h1 (heading 1) to h6 (heading 6).
Youtube
Cats, skateboards and music - at first glance, the YouTube video platform seems to be a difficult place for companies. But YouTube is now the second-largest search engine in the world and therefore an opportunity for companies to achieve successful content marketing with moving images.
Companies can benefit from the enormous reach that can be achieved via this largest video platform. YouTube, with its embed function and mobile apps, made it possible for videos to be shown and consumed everywhere. Embedded videos are often barely noticed on company websites, but YouTube achieves viral effects that generate millions of views.
First and foremost, companies need a strategy and clearly defined goals. Video production in particular can consume enormous resources. Without planning and measuring success, you should therefore not set foot on the platform.
Content marketing is the right tool for companies that want to inspire and retain their target group with emotionally appealing and useful content. If it fits into the strategy, YouTube can be included as a distribution channel.
Examples of videos that the hospital could distribute via YouTube:
- Customers as testimonials - in short videos or as complete case studies
- Personalization of the company through portraits of doctors, nurses, patients, employees
- Visit/product descriptions as videos are good for search engine optimization and can generate more patients
- Tutorials and step-by-step instructions
- Expert interviews
- Answers to typical questions from customers
SlideShare or LinkedIn SlideShare is a file hosting service for sharing and archiving presentations, documents, PDFs, videos and webinars. Presentations can be uploaded in PowerPoint, PDF, Keynote and OpenOffice formats. Registration is required to use the service, which gives you a corresponding user account.
SlideShare has up to 60 million visitors per month.
Benefits of the clinic through SlideShare:
- Raise awareness: SlideShare is a large platform that allows you to make your company better known with your own presentations. Visual content, such as presentations, is usually more popular on social networks such as Facebook than pure text and is therefore liked, commented on and shared more often.
Important: The logo or name of the company should be visible on the slides. - Generate more website traffic: Viewers of a presentation arrive at the presentation themselves via social networks, Google or SlideShare. There are several ways to direct them to your own website: clickable links on the slides of the presentation (important: include links in meaningful places and lead to relevant content on the website) or a direct link in your own profile to your own website. In addition, each presentation can be publicized or integrated via hyperlinks provided on Facebook, Google+, LinkedIn, Pinterest, Twitter or in your own blog.
- Creation of new content: If you have written an interesting article, you can present this content in a SlideShare presentation. This makes it possible to condense a topic that is obviously in high demand and thus increase the added value for readers - and therefore for potential customers. No new content needs to be created, just repackaged. Conversely, a SlideShare presentation can also be conveniently integrated into an article with a similar topic using a simple embed code, thus loosening up the text, offering readers variety and providing them with additional information.
- Better ranking: SlideShare is rewarded by search engines such as Google with trust in the form of good rankings on the search results pages. It is therefore not uncommon for SlideShare presentations to be listed on Google before other articles on the same topic. In addition, the company behind the presentation is easier to find in search engines.
- Positioning as an expert: From the reader's point of view, a single presentation does not make you an expert in this field. However, the multiple treatment and processing of a specific topic makes it clear to the reader in which area your own expertise lies.
- Build trust: Smart slides, paired with concentrated knowledge, make it possible to build initial trust and lead new readers to your website and remain positively in their memory. The presentation is often the first impression the company makes.
Possible content on SlideShare
- Abstracts / entire presentations from trade fairs, events, etc.
- Conversion of blog posts into presentations
- White papers and publications (also as teasers)
- Recording of current developments
- Redesign and preparation of studies
Take note!
- Network: Follow, share and like on SlideShare
Readers can not only share presentations via external networks such as Facebook, but also like and comment directly on SlideShare. You can follow users so that you don't miss any newly published presentations - this allows you to build your own community. To network on SlideShare and make new friends, publishers should also use the commenting and liking functions. - Make yourself discoverable: Slideshare search function
SlideShare is very easy to find on Google. This is partly due to the high reach, number of views and links, but also because of the high-quality and trustworthy content. Your keyword should therefore appear in the filename of each of your presentations. It should also appear clearly in the title, in the description and at the top of the list of keywords. The presentation will then be found both on SlideShare and on Google. The presentation can also be assigned to a specific category.
5 - Meaningful integration of website visitors
Long gone are the days when website visitors were satisfied with accessing static content. Nowadays, so-called "user-generated content", i.e. the content and information left behind by website visitors, is playing an increasingly important role (e.g. ratings, comments, etc.).
For system-related reasons, we are currently unable to integrate this external content on the websites or to manage it in any form whatsoever.
Online surveys are therefore an important way of recording the opinions, statements and content of website visitors. They can be used to obtain important information for the LMU Klinikum and make better use of the website, or even improve it if necessary.
"The customer is king!" has long been the buzzword on the Internet. The website visitor is our customer.
That's why you should start as soon as possible or look for sensible application scenarios or use cases.
How can visitors be involved?
Use of an online survey tool
There are various reasons to conduct a survey on your own website:
- Measure customer satisfaction
- Find out the strengths and weaknesses of the website from the visitors' perspective
- Collect user profiles
- Find out users' expectations
- Increase customer loyalty
- Measure the impact of marketing measures
- Improve the user-friendliness of the homepage
But the most important thing is to increase user interactivity on your website and learn more about your visitors.
The Limesurvey questionnaire tool is designed to enable editors to create and use individual surveys, contact forms or form-like inquiries.
Example: Liver check survey 2010
