Haptics for accessibility in hardware for rehabilitation

Abstract

As haptic interfaces become more widely integrated into rehabilitative therapy, the issue of accessibility of haptic information delivery remains a significant challenge to pursue. This chapter explores the latest research related to the task of making motor task information accessible through haptics in hardware (in combination with software) for physical rehabilitation. The concept of accessibility is first defined within the scope of rehabilitative interfaces is discussed. A literature review is presented which features highlights of related work within several categories of haptic information communication, including environmental augmentation, motion progression, postural correction, and guidance of pacing. A person-centric approach featuring haptic information delivery in autonomous at-home training is detailed in this chapter, including findings related to the proposed system and their implications for accessibility. Finally, methods for evaluation of these interfaces and fading of haptic feedback as user skill improves are discussed with directions for future research.
