Beyond Touch: Accessibility Framework for Mid-Air Haptics in Mobile and Ubiquitous Multimedia Applications

Mid-air haptic technology enables touchless interaction through focused ultrasound and holds promise for inclusive design in mobile and ubiquitous multimedia systems. However, accessibility aspects remain largely unexplored. This poster introduces an accessibility-centered framework for mid-air haptic interaction, building on prior reviews of user experience and technical design. We systematically analyzed 42 studies published between 2014 and 2024 and conducted twelve expert interviews, including accessibility specialists and a visually impaired participant. The analysis highlights three main challenges: low stimulus clarity, limited multimodal feedback, and insufficient personalization. Our proposed framework addresses these gaps through four design dimensions - perceptual optimization, multimodal integration, spatial configuration, and individual calibration. By integrating literature and expert insights, this work advances a structured foundation for accessible mid-air haptic systems and identifies future research directions toward inclusive, touchless interaction in mobile, public, and mixed-reality contexts.
