Virtual reality devices are used for several application domains, such as medicine, entertainment, marketing and training. A handheld controller is the common interaction method for direct object manipulation in virtual reality environments. Using hands would be a straightforward way to directly manipulate objects in the virtual environment if hand...
Conference Paper
As the automotive industry transitions to electric and autonomous vehicles (SAE 2-3) more and more information needs to be reviewed by the driver in real-time. Conventional information presentation techniques are not ideal for reviewing this type of information as it lacks multimodal and cross modal presentation. Haptics, one of the key interaction...
Conference Paper
Mid-air ultrasound skin stimulation is a known technology used to provide haptic feedback for touchless communication. Even though some in-car interaction already takes place with mid-air gestures, the utilization of this type of feedback is still uncommon. In this study we evaluated how environmental vibration affects the recognition of ultrasound...

In this study, we assessed the emotional dimensions (valence, arousal, and dominance) of the multimodal visual-cutaneous rabbit effect. Simultaneously to the tactile bursts on the forearm, visual silhouettes of saltatorial animals (rabbit, kangaroo, spider, grasshopper, frog, and flea) were projected on the left arm. Additionally, there were two lo...

Kinesthetic interaction typically employs force-feedback devices for providing the kinesthetic input and feedback. However, the length of the mechanical arm limits the space that users can interact with. To overcome this challenge, a large control-display (CD) gain (>1) is often used to transfer a small movement of the arm to a large movement of th...

Additional illumination improves the capture of omnidirectional 360° video and images, especially for dark or high-contrast environments. There is no "behind" for 360° cameras, so the placement of lights is a problem. We explore ways to position lights on some 360° cameras, and propose two good locations.
Conference Paper
