Title
Exploring an effective interaction mode for blind mobile users in India
Abstract
Mobile phone is mostly common communicating device in recent time but blind people have limited accessibility to that device. Due to the lack of their visual perception, blind people have different preferences towards interacting with a device. This work aims to find an effective interaction mode to access mobile phone by the visually impaired people in India. In Indian subcontinent people popularly use keypad-based handsets and are well habituated with the key based interaction. But the presence of a huge number of keys in keypad plays negative impact in interaction procedure for our target users. We explored how the detection time for a particular key in a jumble of keys varies with different keypad conditions where target users searched for a key only through the tactile sense. We report the preferable keypad type for our blind mobile users where detection for a particular key is made faster and less error prone. We found that the detection time for a particular key was significantly less and the detection was much accurate in a keypad containing only the functional keys rather than QWERTY or traditional 4x3 keypad.
