IUI '26Multi-Touch Interaction Techniques +2

ReflecTrace: Touchless Hover Interaction on Commodity Smartphones via Corneal Reflection

We propose an approach to detect finger hover inputs on a smartphone screen using corneal reflection images captured by the device’s built-in front camera. This method requires no external sensors or hardware, enabling hover input detection in the near-screen space that is not directly visible to the camera. By levera…

CHI '26Tangible User Interface Design +2

DuoTouch: Passive Two-Footprint Attachments Using Binary Sequences to Extend Touch Interaction

DuoTouch is a passive attachment for capacitive touch panels that adds tangible input while minimizing content occlusion and loss of input area. It uses two contact footprints and two traces to encode motion as binary sequences and runs on unmodified devices through standard touch APIs. We present two configurations w…

CHI '26Olfactory Display & Smell Interaction +2

Amplifying Trigeminal Flavour: Enhancing Spiciness and Coolness by Electrical and Olfactory Stimulation

Digital flavour modulation represents a significant research challenge within Human-Food Interaction. Previous work has focused on modulating basic tastes, while the modulation of trigeminal sensations such as spiciness and coolness remains underexplored. Spicy and cool substances contribute substantially to the senso…

FoodSkin: Fabricating Edible Gold Leaf Circuits on Food Surfaces

We present FoodSkin, a technique for adding interactive elements to foods by implementing edible circuits on the surface of the food. The circuit is easily fabricated using commercially available materials. Existing approaches to enhance the eating experience, such as presenting an electrical taste by making food part…

Acoustic+Pose: Adding Input Modality to Smartphones with Near-Surface Hand-Pose Recognition using Acoustic Surface

To achieve mid-air interactions for smartphones, acoustic-sensing, a technique using the built-in speaker and microphone of smart- phones, is promising. However, detecting hand poses on the near- surface of touchscreens remains challenging due to the arrange- ment of the built-in speaker and microphone. To address thi…

Detecting Thumb-Posture for One-handed Interactions with Smartphone using Acoustic Sensing

This paper presents a novel approach for expanding one-handed interactions using the thumb positioned above the smartphone screen. Our approach is based on acoustic sensing, a technique for leveraging the built-in speaker and microphone of the smartphone without requiring additional sensors or attachments. We explored…

CHI '22Human Pose & Activity Recognition +1

ReflecTouch: Detecting Grasp Posture of Smartphone Using Corneal Reflection Images

By sensing how a user is holding a smartphone, adaptive user interfaces are possible such as those that automatically switch the displayed content and position of graphical user interface (GUI) components following how the phone is being held. We propose ReflecTouch, a novel method for detecting how a smartphone is be…

CHI '21Circuit Making & Hardware Prototyping

LightTouch Gadgets: Extending Interactions on Capacitive Touchscreens by Converting Light Emission to Touch Inputs

We present LightTouch, a 3D-printed passive gadget to enhance touch interactions on unmodified capacitive touchscreens. The LightTouch gadgets simulate finger operations such as tapping, swiping, and multi-touch gestures by means of conductive materials and light-dependent resistors (LDR) embedded in the object. The t…

CHI '20Haptic Wearables +1

Kirigami Haptic Swatches: Design Methods for Cut-and-Fold Haptic Feedback Mechanisms

Kirigami Haptic Swatches demonstrate how kirigami and origami based structures enable sophisticated haptic feedback through simple cut-and-fold fabrication techniques. We leverage four types of geometric patterns: rotational erection system (RES), split-fold waterbomb (SFWB), the overlaid structure of SFWB and RES (SF…

CHI '18Vibrotactile Feedback & Skin Stimulation +1

Double-sided Printed Tactile Display with Electro Stimuli and Electrostatic Forces and its Assessment

Humans can perceive tactile sensation through multimodal stimuli. To demonstrate realistic pseudo tactile sensation for the users, a tactile display is needed that can provide multiple tactile stimuli. In this paper, we have explicated a novel printed tactile display that can provide both the electrical stimulus and t…
