Foundation for improved interaction by individuals with visual impairments through multimodal feedback

Abstract.

Through an investigation of how the performance of people who have normal visual capabilities is affected by unimodal, bimodal, and trimodal feedback, this research establishes a foundation for presenting effective feedback to enhance the performance of individuals who have visual impairments. Interfaces that employ multiple feedback modalities, such as auditory, haptic, and visual, can enhance user performance for individuals with barriers limiting one or more channels of perception, such as a visual impairment. Results obtained demonstrate the effects of different feedback combinations on mental workload, accuracy, and performance time. Future, similar studies focused on participants with visual impairments will be grounded in this work.
