Guess what you touch the touch screen-touch screen TapSense, touch
From the operation of the hardware buttons, the touch screen brought us the emergence of a new interactive experience, a slight touch and slide your fingertips to complete the operation, the device control has brought great convenience.
Touch screen has many advantages, but some touch-screen area is relatively small, and sometimes the user during normal operation may not be careful into the sub-menu, so users have to use your fingertips to carefully poke a small corner of that screen icon. Recently, human-computer interaction at Carnegie Mellon University, Institute researchers are trying to solve this problem, they developed a new system that allows the screen to identify different parts of the user's finger to make a different response, the Executive different tasks.
The touch screen system, called \"TapSense\", it works by analyzing the object voice contact with the touch screen to identify the types of objects. TapSense using a cheap microphone connected device (built-in microphone does not work), it can accept and analyze the object hit the glass touch-screen voice, and identify the finger pads, nails, joints differences. It can also identify the different types of inert materials touch pen, such as wood, resin and foam.
In the smart phone with TapSense or other touch-screen device, an application can identify the different parts of the fingers, in order to achieve different functions. This means that users within a single screen to complete the operation can be greatly increased, people can transform a variety of touch position to change the operating mode and switching functions.
The researchers demonstrated the feasibility of practical application of the technology. Such as finger joints Tap the title bar of the message can pop up a series of instructions without having to open the mail; demonstration in a drawing program example, the user touching the screen with your finger pads, you can free to hand-painted, and when replaced fingertips tap the screen, the program will automatically replace the line tool; in a virtual keyboard interface, the pads with your fingers touch the keyboard the user can be letters input, touch screen with your fingertips can be a digital input, and then struck with a nail Backspace deletes the executable. TapSense also supports multi-touch.
Because it can identify different materials, pen, then when different people use different parts of the finger or stylus touch screen at the same time, TapSense can identify the current use of the touch screen is who, and thus provide different functions for each for instance, some tip as a \"brush\", and some pen is used as the \"Eraser\" and so on.
The researchers said that the \"concept type\" part of the system recognizes four fingers when the accuracy rate of up to 95%, and the distinction between the finger tip, its accuracy rate is 99 percent. (Text / shell Network)
