PianoBand: A Multimodal Wristband Interface for Portable Piano Interaction

Traditional pianos are inherently non-portable, restricting everyday accessibility and on-demand creativity. Existing portable alternatives, largely vision-based with external cameras, suffer from limited range, occlusion, and unreliable contact detection. We present PianoBand, a wrist-worn system integrating an IMU,…

WristPP: A Wrist-Worn System for Hand Pose and Pressure Estimation

Accurate 3D hand pose and pressure sensing is essential for immersive human-computer interaction, yet simultaneously achieving both in mobile scenarios remains challenging. We present WristPP, a camera-based wrist-worn system that estimates 3D hand pose and per-vertex pressure from a single wide-FOV RGB frame in real…

3D Touch Force Estimation from Capacitive Images

Force plays a significant role in our daily interactions with the surrounding environment. However, most touchscreen interactions utilize only touch location, neglecting the potential for incorporating touch force as an additional input modality due to the difficulty in accurately estimating touch force without extra…

FineType: Fine-grained Tapping Gesture Recognition for Text Entry

With the rise of mixed reality (MR) and augmented reality (AR) applications, efficient text input in AR/MR environments remains challenging. We propose \textit{FineType}, a text entry system using tapping gestures with finger combinations and postures on any flat surface. Using a wristband with an IMU and an infrared…

FingerGlass: Enhancing Smart Glasses Interaction via Fingerprint Sensing

Smart glasses hold immense potential, but existing input methods often hinder their seamless integration into everyday life. Touchpads integrated into the smart glasses suffer from limited input space and precision; voice commands raise privacy concerns and are contextually constrained; vision-based or IMU-based gestu…

PrintShear: Shear Input Based on Fingerprint Deformation

Most touch-based input devices, such as touchscreens and touchpads, capture low-resolution capacitive images when a finger touches the device's surface. These devices only output the two-dimensional (2D) positions of contacting points, which are insufficient for complex control tasks, such as the manipulation of 3D ob…

Estimating 3D Finger Pose via 2D-3D Fingerprint Matching

Touchscreens have become the primary input devices for smartphones, tablet computers, and other intelligent devices over the past decades. While for the most pervasive commercial devices, only 2D touch positions on the screen are utilized as interaction inputs. To extend the richness of the input vocabulary, some rese…
