随着计算机技术应用领域的不断扩展,计算机已不仅仅是一个单纯的计算或储存工具,其服务对象也从专业技术人员转向更多的普通用户。人们越来越注重人机交流的方便性,对计算机输入技术的要求也越来越高。计算机输入设备这个行业正是顺应了这一发展趋势,得到了迅速的发展。尤其是鼠标器,作为最基本的一种电脑输入工具,已无处不在,可以想象,现在的PC用户,如果离开了鼠标,会是多么不方便。 鼠标器的基本功能及类型: 鼠标器是电脑指标输入装置(Pointing Device)的一种,起源于1963年,由Douglas Englebart于美国加州Menlo Park的斯坦福研究所(Stanford Resarch Insti-tute)发明。当时的构想是:使用者移动鼠标时,它以一对滚轮来转动轴心,同时计算出水平及垂直的位移,屏幕上的游标便之移动。产生一个相对于屏幕的位置
With the continuous expansion of the field of computer technology, the computer is not only a simple calculation or storage tool, the service object is also shifted from professional and technical personnel to more ordinary users. People pay more and more attention to the convenience of human-computer communication, and the requirements for computer input technology are also getting higher and higher. Computer input device This industry is in conformity with this trend of development, has been rapid development. Especially the mouse, as a basic kind of computer input tool, has been ubiquitous, you can imagine, now the PC users, if left the mouse, how inconvenient. Mouse Functions and Types: A mouse is a type of Pointing Device that originated in 1963 and was invented by Douglas Englebart at Stanford Resarch Instiute in Menlo Park, California. At that time, the idea was that when the user moved the mouse, it rotated the axis by a pair of rollers, and at the same time, calculated the horizontal and vertical displacement, and the cursor on the screen moved. Produces a position relative to the screen
