Question

please no hand writing

In real-life, interfaces like bank ATM, car interface, mobile applications etc. are often used by different type of users. Describe three groups of users with special needs. For each group, discuss different features that make a good interface for them.

Answer 1

Solution :

First of all understand what is special needs,
Special needs is defined as an individual with a mental, emotional, or physical disability. An individual with special needs may need help with:

• Communication
• Movement
• Self-care
• Decision-making

Now disscussing three groups of user with special need.

Three populations of users with unique needs which could need improved/enhanced user interfaces are people who are hearing-impaired, sight-impaired, or movement-impaired.

1. People with damaged or lack of hearing need interfaces which do not rely on that sense to function. Therefore, an interface which cues users with a ‘ding’ sound when an event takes place might consider pairing the noise with a blinking element on the screen or another visual way of getting one’s attention.

2. For those with sight-impaired or no vision, navigating and using the interface cannot rely on sight to function. Using an ATM as an example interface, interfaces could be improved through narrative prompts letting users know what actions are available to them and either brail atop the buttons which control those actions or verbal control of those actions.( Image take from google)
   
   
   
   
3. Movement-impaired individuals need interfaces which do not necessarily require them to move to interact with the system. For these users in the ATM example, audio control might be a way to allow them better access to the system without making them perform impossible or uncomfortable tasks.
