Need: User choice of portrait or landscape view

  1. Jeremy uses a wheelchair and has a tablet mounted on the wheelchair. He cannot change the position of the tablet, which has a landscape orientation.
  2. Naomi has repetitive strain injuries and protects her hands by limiting scrolling on her tablet and phone. She positions her devices vertically when she is reading so she can limit scrolling.
  3. Mike has repetitive strain injuries and can change the physical orientation of his tablet, but needs to limit that activity. He is cutting and pasting from one application to another and needs both applications to be in the same orientation so he is not forced to frequently change the physical orientation of his tablet.

Need: text size

  1. Joe has low vision and needs increase the size of text on the screen. Joe uses the large text feature in the platform settings to increase the text size.
  2. Kate has low vision and needs to use the pinch zoom feature to increase the size web content in the browser. Using the platform zoom feature along with scrolling in web sites is challenges and thus pinch zoom works more affectively and only requires her to use 1 finger for scrolling. Pinch zoom also allows her to scroll in one viewport rather than the platform zoom which requires scrolling the page viewport and scrolling the zoomed viewport.
