Midair User Interfaces Employing Particle Screens

Projected walk-through fogscreens can be used to render user interfaces, but lack inherent tactile feedback, thus hindering the user experience. This study examines this by investigating wireless wearable vibrotactile feedback on mid-air hand gesture interaction with a large fogscreen. Participants (n = 20) selected objects from a fogscreen by tapping and dwell-based gestural techniques. The results showed that the participants preferred the tactile feedback. Further, while tapping was the most effective selection gesture, dwell-based target selection required haptic feedback to feel natural.

“…A wearable projector enables image projection onto any surfaces wherever the wearer goes, it can project onto any object in-front of the viewer, or even the wearer's own body (Harrison and Faste 2014). Mid-air or free-space display technology allows the projection of images without a physical ''surface'' and various media are proposed to establish non-turbulent air flow of particle clouds in free space as projection screens that viewers can walk-through (Rakkolainen et al 2015).…”

The enhancement of human senses electronically is possible when pervasive computers interact unnoticeably with humans in ubiquitous computing. The design of computer user interfaces towards ''disappearing'' forces the interaction with humans using a content rather than a menu driven approach, thus the emerging requirement for huge number of non-technical users interfacing intuitively with billions of computers in the Internet of Things is met. Learning to use particular applications in ubiquitous computing is either too slow or sometimes impossible so the design of user interfaces must be naturally enough to facilitate intuitive human behaviours. Although humans from different racial, cultural and ethnic backgrounds own the same physiological sensory system, the perception to the same stimuli outside the human bodies can be different. A novel taxonomy for disappearing user interfaces (DUIs) to stimulate human senses and to capture human responses is proposed. Furthermore, applications of DUIs are reviewed. DUIs with sensor and data fusion to simulate the sixth sense is explored. Enhancement of human senses through DUIs and context awareness is discussed as the groundwork enabling smarter wearable devices for interfacing with human emotional memories.

“…Mixed reality systems have also been used for novel playful and entertaining experiences; for example, Hoshi et al [61] describe a mixed reality experience where users feel raindrops falling onto their hand, or the footsteps of a small elephant that walks across the palm. Similar concepts have been widely explored (e.g., [55], [61], [94], [98], [111]- [113]), with spatially congruent visual and haptic content, an example of which is shown in Fig. 10.…”

Ultrasound haptics is a contactless haptic technology that enables novel mid-air interactions with rich multisensory feedback. This paper surveys recent advances in ultrasound haptic technology. We discuss the fundamentals of this haptic technology, how a variety of perceptible sensations are rendered, and how it is currently being used to enable novel interaction techniques. We summarize its strengths, weaknesses, and potential applications across various domains. We conclude with our perspective on key directions for this promising haptic technology.
