Technical Considerations

For Technical considerations these are things you need to consider when building your site and include:

Note: If you are creating a site based on a specific scenario each of these factors needs to be directly related to your context.

For example, if a user was looking at an Adventure  Tourist site they would probably access it on a mobile device if they were looking up directions.  

Physical

These are human physical things. Physical is more than vision or mobility, and includes

• visual impairments, e.g.  colour blindness.

• mobility issues

• Cognitive problems. For cognitive think of Anxiety  (reassure if they do spring wrong), Inattention (Minimise design elements), Depression (allow anonymous viewing), Memory loss (breadcrumbs, pop-ups, passwords), Reading disorders (Dyslexia), Problem Solving Disorders (broken links), Visua; comprehensive disorders (Distinguishing similar objects). For details of these you may find it useful to refer to the Blog post “Cognitive accessibility in web design” by Tuba Ayyubi (Ayyubi, 2020).

So,

• How will you handle the various media types (e.g. audio/video) to allow for them to be accessible?

You can use techniques such as

• sensible colour combinations, button sizes, alternative text for images, responsive text sizes, audio, and video (text transcripts/subtitles), appropriate language, translations of any terms (e.g. Māori ), cater for an international audience (English as a second language), etc. 

Searchability

What can you do to improve it's search engine rankings (SEO), e.g.,

• sensible URL, clear headings, promotion (e.g., through social media), include html techniques (e.g., title tag, meta-tags, Heading styles, alt tags for images, text for videos, using context tags (HTML elements reference, 2023) , etc.), responsive design 

• Not that this is always changing so use an internet search to find out what are important techniques in current search engine algorithms.

Access (Device: mobile phone or PC, and Browsers: responsiveness, speed, etc) 

• What Devices or Browsers do you expect your users to use?

• What can you do to make the site displayable on a wide range of devices?

  • Responsive design

• How can you optimise the performance? e.g., 

  • Image sizes, 

Note: Image resolution (dpi) does not have much impact on responsiveness, the actual size (width & height) of an image does. For example, if you take an image on a phone at 11Mpix they are 4608 x2304 which is way bigger than the typical screen size (and huge from a web point of view on file/download size).
