With a touchscreen display, the interface is limited to the screen that supports input only. Well, what if all the surfaces of the objects can be transformed into a digital interface?
That's the idea behind the development of the concept of the "Magic Finger" by Autodesk Research scientists at the University of Alberta and University of Toronto, Canada.
Through a small instrument mounted on the tip of a finger, users can perform Magic Finger gestures on various surfaces and produce like a touchscreen input. Movements such as finger gestures pinch-to-zoom can be done in the air, without touching the screen.
The secret is a pair of optical sensors mounted on the tool. One of the sensors that have low resolution and high speed are used to track the movement. Other sensors with high resolution can detect 32 different types of surfaces to an accuracy of 98 percent.
Finger Magic can recognize surfaces touched by the user and convert it as a touchscreen display that accepts input from the touch of a finger.
For example, to change the current slide presentation, users do not need to touch the computer at all, but simply by swiping a finger in the air alone.
Want to turn down the volume of the music when you're relaxing in bed? No need to run to the computer to reach the volume buttons, just slide your finger up and down on the surface of the mattress sheets.
This device can be programmed to perform actions according to the type of objects it detects surface.
Other things that can be done including Magic Finger scan QR code and use its camera as a periscope.
Tim Autodesk hopes to one day be able to realize the Magic Finger in the form prangkat actually smaller than existing devices today.
