Haptic Technology for Hearing Loss: A Systematic Review of Technical Feasibility, Usability, and User Experience

Abstract

Nearly 27 million Americans aged 50 and up experience hearing loss, with varying degrees and types of impairment. Haptic technology offers promising support for these individuals, either as standalone solutions, complements to existing devices, or alternatives for those not benefitting from traditional devices. This systematic review investigates the technical feasibility, usability, and user experience of haptic technology for hearing assistance. Using the PRISMA method, eight relevant articles were identified. Results indicated a focus on technical feasibility, with positive outcomes for direction of arrival, sound localization, and sensory substitution. Some studies also investigated usability and user experience, exploring user preferences, social acceptance, and integration with existing devices. The limited studies constrain the ability to draw substantial conclusions. Nevertheless, this review offers insights to guide future device development, highlighting the need for more research in usability and user experience alongside technical advancements.
