摘要：现如今科技越来越发达，人们渴望解放双手来掌控事情。在平时的生活中我发现大部分人对键盘这个物品又爱又恨，爱在他很方便的操控电脑计算机，恨在他体积较大不易携带，所以我希望设计一个无线手套键盘来替代如今的键盘。无线手套键盘相比较于传统键盘有摆脱了有线的限制，能够更加灵活自由的对PC或其他与无线手套键盘相连的设备进行输入和进行一些简单的控制（比如空格，换行等）。在键盘字母的排布与设计上追求达到最大程度的符合人体学，让用户能够真正的解放双手，方便控制，实现灵活自由的特点。48980

Design of wireless glove keyboard

Abstract: Nowadays, science and technology have been more and more developed, people are eager to liberate their hands to control other things. In the usual life I found that most of the people can’t say love or hate on the keyboard items. It can control computer very conveniently but it is to large and not easy to carry out. So I would like to design a wireless glove keyboard to replace keyboard we are using today. Compared to the traditional keyboard, the wireless glove keyboard can get rid of the limitation of the cable so that it can be more flexible to be free to PC or other equipment connected with the wireless glove keyboard for inputing and taking some simple control (such as spaces, newlines, etc.). In the arrangement and design of letters on the keyboard pursuit to conform the human body to let the users set their hands free. All of this are aimed to make the wireless glove keyboard’s controling be more convenient and flexible.
