SGToolkit: An Interactive Gesture Authoring Toolkit for Embodied Conversational Agents

Non-verbal behavior is essential for embodied agents like social robots, virtual avatars, and digital humans. Existing behavior authoring approaches including keyframe animation and motion capture are too expensive to use when there are numerous utterances requiring gestures. Automatic generation methods show promisin…

AtaTouch: Robust Finger Pinch Detection for a VR Controller Using RF Return Loss

Handheld controllers are an essential part of VR systems. Modern sensing techniques enable them to track users' finger movements to support natural interaction using hands. The sensing techniques, however, often fail to precisely determine whether two fingertips touch each other, which is important for the robust dete…

OddEyeCam: A Sensing Technique for Body-Centric Peephole Interaction using WFoV RGB and NFoV Depth Cameras

The space around the body not only expands the interaction space of a mobile device beyond its small screen, but also enables users to utilize their kinesthetic sense. Therefore, body-centric peephole interaction has gained considerable attention. To support its practical implementation, we propose OddEyeCam, which is…

DeepFisheye: Near-Surface Multi-Finger Tracking Technology Using Fisheye Camera

Near-surface multi-finger tracking (NMFT) technology expands the input space of touchscreens by enabling novel interactions such as mid-air and finger-aware interactions. We present DeepFisheye, a practical NMFT solution for mobile devices, that utilizes a fisheye camera attached at the bottom of a touchscreen. DeepFi…

FS-Pad: Video Game Interactions with a Force Feedback Gamepad

Force feedback has not been fully explored in modern gaming environments where a gamepad is the main interface. We developed various game interaction scenarios where force feedback through the thumbstick of the gamepad can be effective, and categorized them into five themes. We built a haptic device and control system…

MagTouch: Robust Finger Identification for a Smartwatch Using a Magnet Ring and a Built-in Magnetometer

Completing tasks on smartwatches often requires multiple gestures due to the small size of the touchscreens and the lack of sufficient number of touch controls that are easily accessible with a finger. We propose to increase the number of functions that can be triggered with the touch gesture by enabling a smartwatch…
