+ - Is this the End of the Computer Mouse?->

The wearable 3D Touch device is fitted with an accelerometer and gyroscope, and lets people control an onscreen mouse using just a wave of their finger.

3DTouch enables users to user their fingers or thumb as a 3D input device with the capability of performing 3D selection translation, and rotation,' explained the researchers. 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. This presents a low-cost solution to designing and implementing such a device.
Modular solutions like 3DTouch opens up a whole new design space for interaction techniques to further develop on.

'With 3DTouch, we attempted to bring 3D interaction and applications a step closer to users in everyday life.

. Control-VR has the 10 finger version of the same idea already working as a prototype. The addition of a laser mouse sensor is new, but why is that worth a paper? .

Control-VR is still in their pre-ordering phase. Similar interfaces like Fin, Ring or other emerging prototypes. These including 3DTouch just come out in the same time!

nobody cares to hold sth the mouse is popular because u can get stuff done with minimum energy and high efficiency, add a UP down key on the mouse or keyboard and u got ur 3rd dimension,

So how would you use the mouse in a spatial setting such as the Cave Automatic Virtual Environments (CAVE)?

Sorry to break it to you guys, but this has already been done in a more polished form.

There is this thing called Ring as well. First of all, they are all just prototyping not on the market yet. So is 3DTouch. Second of all, 3DTouch serves a different niche market of 3D applications while those two don't.

And from the summary: "...respond to a set of pre-programmed gestures...", it's where this one will go wrong, too.

I totally agree, even the LEAP allows user-defined gestures. However, for this device "pre-programmed gestures" can always be "re-programmed" as users desire because they are eventually just gestures (not fixed buttons or keys).

Waving your arm around to interact with the 3d space will surely tire your arm out if you are sitting at a computer.

Fatigue problem you mentioned is exactly right... as it occurs with Kinect, LEAP, and Wii... that's why this touch device has potential with less fatigue incurred.

Desktop input devices such as mouse, joystick, touch-pads possess high precision and responsiveness due to a supporting surface, and incur less fatigue than spatial mid-air input devices like Wiimote or Kinect. However, these desktop devices are not mobile, and can only support relative positioning.

In spatial environments, tracking input devices such as Kinect, OptiTrack, RazorHydra support absolute positioning; however, they require a base reference. Moreover, interaction enabled by these devices is fatiguing. GPS tracking devices support absolute positioning; and are self-contained! However, their accuracy is within feets, not usable for room-sized tracking volume.

With the explosion of 3D applications in everyday life across various 3D platforms, it is necessary to have a self-contained 3D input device that allows user to interact with 3D applications anytime, anywhere! And this device needs to incur less fatigue than mid-air gestures in order for users to practically use over a long time.

We designed 3DTouch, a novel 3D wearable input device, worn on the fingertip for 3D manipulation tasks. 3DTouch is self-contained, and designed to universally work on various 3D platforms. 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. Modular solutions like 3DTouch opens up a whole new design space for interaction techniques to further develop on."
