3D applications appear in every corner of life in the current technology era. Just like the prototype, created by Anh Nguyen and Amy Banic from the University of Wyoming in Laramie, lets users interact with their computers just like a computer mouse except by moving a finger, and could eventually replace your regular computer.
Named 3DTouch, The device works with a 3D accelerometer, magnetometer and gyroscope, similar to those found in smartphones. A button on the surface of the forefinger functions like the left-click function of a traditional mouse and the device uses “optical flow” sensors to track movement against any flat surface.
3DTouch enables users to use their fingers or thumb as a 3D input device with the capability of performing 3D selection, translation and rotation. It is designed to fill the missing gap of a 3D input device that is self-contained, mobile and universally working across various 3D platforms. With 3DTouch, we attempted to bring 3D interaction and applications a step closer to users in everyday life.”
According to Anh Nguyen,
We present 3DTouch, a novel wearable 3D input device worn on the fingertip for 3D manipulation tasks. 3DTouch is designed to fill the missing gap of a 3D input device that is self-contained, mobile, and universally works across various 3D platforms. This paper presents a low-cost solution to designing and implementing such a device.
Our approach relies on a relative positioning technique using an optical laser sensor and a 9-DOF inertial measurement unit. The device employs touch input for the benefits of passive haptic feedback, and movement stability. On the other hand, with touch interaction, 3DTouch is conceptually less fatiguing to use over many hours than 3D spatial input devices. We propose a set of 3D interaction techniques including selection, translation, and rotation using 3DTouch. An evaluation also demonstrates the device’s tracking accuracy of 1.10 mm and 2.33 degrees for subtle touch interaction in 3D space. We envision that modular solutions like 3DTouch opens up a whole new design space for interaction techniques to further develop on. With 3DTouch, we attempt to bring 3D applications a step closer to users.
