Fog screens are a projection medium for mid-air graphics, they are see-through and reach-through. Fog screens are traditionally generated by laminar flows coming out of linear outlets and thus are usually static. Here, we show that ultrasonic beams create a streaming...
Contactless haptic technologies deliver tactile feedback remotely, eliminating the need for direct skin contact and reducing setup time. However, current technologies have relatively weak intensity or coarse perception resolution. This paper proposes SparkTouch, an...
Devices capable of stroking the user’s forearm are being explored for digitally mediated touch but are mainly contact-based. We propose ElectroCaresses, the use of electrostatic piloerection to convey contactless gentle strokes by generating dynamic patterns of...
Volumetric displays render true 3D graphics without forcing users to wear headsets or glasses. However, the optical diffusers that volumetric displays employ are rigid and thus do not allow for direct interaction. FlexiVol employs elastic diffusers to allow users to...
Electric plasma can be formed in mid-air, making an ionic channel that transfers electrical current. This current can power high-voltage electronics, kill bacteria, produce tactile sensations or be used for welding. However, the formation of the spark is chaotic and...
A laser pointer is a commonly used device that does not require communication with the display system or modifications on the applications, the presenter can just take a pointer and start using it. When a laser pointer is used on a volumetric display, a line rather...
Asymmetric vibrations are known to produce a pulling sensation when stimulating the human hand. This effect has been exploited as a means of guidance. We conducted a user study to compare asymmetric vibrations, simple vibration, and sound cues for guidance in terms of...
We present four technologies to deliver contactless haptic stimuli for enriching Virtual Reality (VR) experiences. The technologies are electrostatic piloerection, focused light-induced heat, electric plasma, and ultrasound; the user does not require to wear or touch...
Ultrasonic fields can push and levitate particles, heat up materials, induce contactless tactile stimuli, or affect the blood-brain barrier. Current phased-arrays can create dynamic amplitude patterns, but their quality may be insufficient due to the limited density...
In this project, we create artificial piloerection using contactless electrostatics to induce tactile sensations in a contactless way. Firstly, we design various high-voltage generators and evaluate them in terms of their static charge, safety and frequency response...
Programmable matter can change its shape, stiffness or other physical properties upon command. Previous work has shown contactless optically controlled matter or magnetic actuation, but the former is limited in strength and the latter in spatial resolution. Here, we...
LevPet combines affective computing and magnetic levitation to create an artificial levitating pet with affective responses and novel ways of moving to express emotions. Our interactive pet can recognise the user’s emotional status using computer vision, and respond...
