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…

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…

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…

Single-tap Latency Reduction with Single- or Double- tap Prediction

Touch surfaces are widely utilized for smartphones, tablet PCs, and laptops (touchpad), and single and double taps are the most basic and common operations on them. The detection of single or double taps causes the {\it single-tap latency problem}, which creates a bottleneck in terms of the sensitivity of touch input…

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…

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…

TiltChair: Manipulative Posture Guidance by Actively Inclining the Seat of an Office Chair

We propose TiltChair, an actuated office chair that physically manipulates the user's posture by actively inclining the chair's seat to address problems associated with prolonged sitting. The system controls the inclination angle and motion speed with the aim of achieving manipulative but unobtrusive posture guidance.…

Ohmic-Sticker: Force-to-Motion Type Input Device that Extends Capacitive Touch Surface

We propose ``Ohmic-Sticker'', a novel force-to-motion type input device to extend capacitive touch surfaces. It realizes various types of force-sensitive inputs by simply attaching on to commercial touchpads or touchscreens. A simple force-sensitive-resistor (FSR)-based structure enables thin (less than 2 mm) form fac…

Ohmic-Touch: Extending Touch Interaction by Indirect Touch through Resistive Objects

When an object is interposed between a touch surface and a finger/touch pen, the change in impedance caused by the object can be measured by the driver software. This phenomenon has been used to develop new interaction techniques. Unlike previous works that focused on the capacitance component in impedance, Ohmi…
