Abstract
Although cell phones have become increasing popular and much more innovative these days, most input interfaces still rely on the sense of sight. In order to improve the usability and convenience of using a cell phone for the visually impaired, this research fo- cuses on the tactile touch when using cell phone buttons – a non-visual operation. We have designed two kinds of tactile function buttons and two kinds of tactile number buttons. We test the designs and analyze the cognition behavior of the users using non-visual think-aloud protocols and interviews. The result shows people tend to recognize shapes by a clear edge outline and are able to distinguish several basic features.
