BioHaptics: Emotion Modulation via Biosignal-Inspired Ultrasonic Mid-air Haptics in Video-Watching Experiences

Ultrasonic mid-air haptics (UMH) offers a novel way to modulate affective responses through contactless, biosignal features inspired haptics (i.e., BioHaptics). Yet, the effects of different BioHaptics on affective responses of emotions experienced during video-watching context are unclear, limiting the flexible emoti…

Illusory-UMH: A Systematic Comparison of Tactile Illusions and Modulation Techniques in Ultrasonic Mid-air Haptics

Spatiotemporal modulation (STM) is the current de facto standard technique for generating continuous tactile sensations in Ultrasonic Mid-Air Haptics (UMH). However, like other techniques, it assumes a uniform sensitivity distribution across the hand. Tactile illusions, such as the funneling effect (FE) and cutaneous…

Controlled-STM: A two-stage model to predict user’s Perceived Intensity for Multi-point Spatiotemporal Modulation in Ultrasonic Mid-air Haptics

Multi-point STM offers a great range of parameters (i.e., drawing frequency, number of points) to produce different tactile sensations. However, existing studies offer limited insight on the effects of these parameters, and ignore their effect on the physical stimuli delivered, limiting effective haptic design. We…

Responsible Innovation of Touchless Haptics: A Prospective Design Exploration in Social Interaction

The rapid development of touchless systems has introduced many innovations in social interaction scenarios in recent years. People now can interact with touchless systems in social applications that are aimed to be used in everyday situations in the future. This accelerated development makes us ask, what will the next…

Multi-point STM: Exploring the effect of drawing speed and the number of focal points on perceived intensity, valence and arousal in ultrasonic mid-air haptics

Spatiotemporal modulation (STM) is used to render tactile patterns with ultrasound arrays. Previous research only explored the effects of single-point STM parameters, such as drawing speed ($V_d$). Here we explore the effects of multi-point STM on both perceptual (intensity) and emotional (valence/arousal) responses.…

MindTouch: Effect of Mindfulness Meditation on Mid-Air Tactile Perception

As we constantly seek to improve and expand upon the capabilities of technology, we frequently wonder whether we use technology to its fullest extent. Studies indicate that increasing our awareness and mindfulness of our senses may lead to a journey of unexplored experiences. In this paper, we focus on the perception…
