Adaptive Auditory Feedback Mechanism of Visual Impaired

There is a lot of work done in HCI research area, due to this auditory interface develops for visually impaired people that assist them to work with desktop environment easily. To enhance better design, designer faces many challenges to develop auditory feedback system. This study purposed an new method named as adaptive auditory feedback system, which is continuous switching of speech-based feedback system (i.e. sound, music) to non-speech-based feedback system (i.e. spearcone) according to user state of interaction. As a visually impaired person who frequently access desktop system does not need continuous instructions. Experiment done on sixteen visually impaired people and result shows that adaptive auditory feedback system is efficient then only one particular method (speech-based or non-speech-based). User can choose any type of instruction according to need and want that improve usability experience. Result and discussion shows highest satisfaction level of visually impaired people regarding adaptive auditory feedback. In future, same type of adaptive auditory feedback system may implement on mobile applications rather than desktop environment.
