How would you protect your privacy? Is it complicated to set a password that you sometimes forget or use fingerprint recognition? Or more advanced iris scanning, voice recognition? These methods are too much of a hassle. You can make it easy to change. The way, such as the keyboard.
Each user has his own unique typing pattern, such as the pressure applied to each key and the time interval between two key presses. According to Wei Feng, Feb. 2, recently, the research team of Zhong Lin Wang from Georgia Institute of Technology has developed a special smart keyboard based on this principle that can accurately identify users through the user's typing method.
It is reported that this keyboard does not recognize the two states of pressing and releasing as the normal keyboard. Instead of relying on the up and down switches, the keyboard is covered with four transparent films. Two of the layers are indium tin oxides serving as electrodes, separated by PET plastic. There is a layer of FEP plastic on top of the electrode to collect the static electricity generated by the friction between the fingers and the keyboard.
The advantage of this design is that the keyboard can record the complex electrical signals received by each key and create various typing modes as unique tags for each user. The R&D staff had 104 volunteers use the keyboard to make 4 “touch†tests. The test results showed that only a small amount of data was needed to allow the keyboard to recognize the user's typing pattern fairly accurately.
In addition, the keyboard can store static electricity on the fingertips, enough power to drive the Bluetooth transmitter to enable the keyboard to achieve wireless capabilities, and even support third-party low-energy devices. However, the current model is still unable to achieve this function.
It is worth mentioning that the keyboard's unique design and production materials make the cleaning of the keyboard much easier. Wang told us: "Because plastic can separate liquids, it will not break even if you spill a cup of coffee."
Zhong Lin Wang believes that this keyboard is very competitive in terms of cost and durability. Think about it too, not only to identify the identity, dirt, water, but also use your fingertips to generate electricity on your own, who wouldn’t want such a keyboard?
