StegoType: Surface Typing from Egocentric Cameras

Text input is a critical component of any general purpose computing system, yet efficient and natural text input remains a challenge in AR and VR. Headset based hand-tracking has recently become pervasive among consumer VR devices and affords the opportunity to enable touch typing on virtual keyboards. We present an a…

TouchInsight: Uncertainty-aware Rapid Touch and Text Input for Mixed Reality from Egocentric Vision

While passive surfaces offer numerous benefits for interaction in mixed reality, reliably detecting touch input solely from head-mounted cameras has been a long-standing challenge. Camera specifics, hand self-occlusion, and rapid movements of both head and fingers introduce considerable uncertainty about the exact loc…

Decoding Surface Touch Typing from Hand-Tracking

We propose a novel text decoding method that enables touch typing on an uninstrumented flat surface. Rather than relying on physical keyboards or capacitive touch, our method takes as input hand motion of the typist, obtained through hand-tracking, and decodes this motion directly into text. We use a temporal convolut…
