Activity Summary

At this session, a participant with low-vision interacted with visual components of the existing prototype.

To determine function of buttons of prototype can be distinguished
To recognize visual preference for component on prototype for users with low vision

Symbols for action buttons can be ambiguous to their function and could be clarified by adding words
User selected the ‘Play’ button when asked to delete all steps
The small circular nodes in between blocks on sequences were interpreted as blocks for up and down instead of separation
Scroll bar was difficult to find on the prototype. No issues with scroll bar use once it was found
When a movement in sequence was selected, the grey dashed outline was not easily distinguished. User could not identify which movement was selected
Deleting steps was easy in this session because the user took time to be familiar with the interface prior to the session
For a person with low vision, there is difficulty with manuals/menus that involves trouble reading and tracking activity (can get lost where things are happening on the page)
Some UI features preferred: being able to zoom into text, using speech commands
User suggested to include an option to include feedback/comments
There is difficulty adding steps when the sequence becomes longer. When the sequence went past the screen, the “add” button was further down and the ‘start’ button became invisible. User could not remember where the start button was located
Using a head tracker to add steps was time-consuming
Difficulty differentiating different panels of prototypes and which movements were being selected on sequence

Provide options to change size and colours of user interface. Some colours may be hard to see due to low contrast
To increase focus for the user who has difficulty tracking on page/screen, place content (e.g. control panels) in the middle of screen or a more central location
To increase visibility, increase size and boldness for icons and text
Indicate selected movement in sequence with a thick high contrast outline (e.g. black border)
The idea of a dashboard or collection of functions (e.g. similar to a start menu on Microsoft computers) for actions (i.e. add, delete, scroll) should be fixed (i.e always present) on screen
