Goals

  • To determine whether current prototype settings had visual component to be identified

  • To determine how to support low-vision user with scrolling when sequence that extends beyond window 

Notes from the session

  • The circle that appears on ‘Loop’ under action controls could not be identified by the user.

  • User has a preference for scrolling by using up and down keyboard buttons.

  • Drag and drop was a new feature for the user. 

Notes for C2LC design

  • Setting high contrast icons is mandatory for low vision users. Other colours of preference include red.

  • Place the up and down arrows side-by-side
