Effective Scheme to Control Multiple Application Windows for Screen Reader Users with Blindness

摘要

Blind people use screen readers (SRs) to manipulate their personal computers. Due to the various voices and sounds handled by the screen reader, the more application windows open, the heavier the cognitive burden it feels, and the lower its performance becomes. In this paper, we propose a support scheme that enables SR users with blindness to effectively control multiple windows. As a proof-of-concept system, we propose a set of shortcut key buttons that provide direct jumps to the targeted window through a simple action. According to the evaluation results, our shortcut key buttons had positive effects on reducing the subjective workload and the number of keystrokes.
