Mid-Air Haptic Interfaces for Interactive Digital Signage and Kiosks

Digital signage systems are transitioning from static displays to rich, dynamic interactive experiences while new enabling technologies that support these interactions are also evolving. For instance, advances in computer vision and face, gaze, facial expression, body and hand-gesture recognition have enabled new ways of distal interactivity with digital content. Such possibilities are only just being adopted by advertisers and retailers, yet, they face important challenges e.g. the lack of a commonly accepted gesture, facial expressions or call-to-action set. Another common issue here is the absence of active tactile stimuli. Mid-air haptic interfaces can help alleviate these problems and aid in defining a gesture set, informing users about their interaction via haptic feedback loops, and enhancing the overall user experience. This workshop aims to examine the possibilities opened up by these technologies and discuss opportunities in designing the next generation of interactive digital signage kiosks.
