Normal people can click the mouse and type on the keyboard with their hands, but how can the people with upper limb disabilities click the mouse and surf the Internet? Recently, several university students from the Nanjing University of Science and Technology came up with an idea to invent a device where people can control a mouse with their feet. They have called the mouse "Talang."

The "Talang" mouse looks like a large slipper with a blue waves design. According to the students that invented it, wearing the "slipper," people can click the left mouse button by pressing the slipper with their forefoot, click the right button by pressing the slipper with their heel and browse the websites by moving their foot.

Li Yunlong, a student at the Instrument Science and Technology department of the School of Mechanical Engineering under the Nanjing University of Science and Technology, is the head of the invention team. He said that through constant research, amendment and discussion, the five members in their team had looked for a variety of information on the Internet and finally determined the design program of the "Talang" mouse in early April 2010. Then, they began to design circuits, make PCB and debug programs.

According to sources, the "Talang" mouse has won the first prize in the MEMS Sensor Application qualifying competition held in Jiangsu and Anhui provinces in China for the Fourth MEMSIC Cup and is about to compete for the championship in the national finals.
