Mid-air haptic technology can render a plethora of tactile sensations including points, lines, shapes, and textures.To do so, one requires increasingly complex haptic displays. Meanwhile, tactile illusions have had widespread success in the development of contact and wearable haptic displays. In this paper, we exploit the apparent tactile motion illusion to display mid-air haptic directional lines; a prerequisite for the rendering of shapes and icons. We present two pilot studies and a psychophysical study that contrasts a dynamic tactile pointer (DTP) to an apparent tactile pointer (ATP) in terms of direction recognition. To that end, we identify optimal duration and direction parameters for both DTP and ATP mid-air haptic lines and discuss the implications of our findings with respect to haptic feedback design, and device complexity.

“…While still in development, this technology has been envisioned to assist humans in application scenarios that are commonly found in our daily life and social interactions such as interactive displays in urban environments (e.g., shops, train stations and shopping malls) [63], museum exhibitions [102], in cars dashboards [92], in hospitals assisting surgery [75] and in calming social settings [66]. Additionally, with the recent covid-19 pandemic, mid-air haptics has been also suggested to be a promising solution to promote a touch-free and hygienic alternative to interact with technology (public displays, elevators) in social and public spaces [50,95].…”

“…Also motivated by COVID-19, Singhal et al designed an interactive simulation of a contactless elevator panel with mid-air touch feedback and comprehensive accessibility considerations [47]. Users could not only feel mid-air haptic feedback on contact with the panel buttons corresponding to the different floors, but could also feel their Braille representations using a similar implementation to that described by Paneva et al [48].…”

Mid-air haptic feedback presents exciting new opportunities for useful and delightful interactive systems. However, with these opportunities come several design challenges that vary greatly depending on the application at hand. In this chapter, we reveal these challenges from a user experience perspective. To that end, we first provide a comprehensive literature review covering many of the different applications of the technology. Then, we present 12 design guidelines and make recommendations for effective mid-air haptic interaction designs and implementations. Finally, we suggest an iterative haptic design framework that can be followed to create a quality mid-air haptic experience.
