随着微机的进一步微型化,出现了便携机,随后又出现了笔记本电脑,但是更进一步的微型化却碰到了困难,因为键的大小必须与手指的大小相一致,手指不能缩小,键盘自然也不可能无限制地缩小.其实,目前的笔记本电脑仍不能称为真正的“笔记本”.虽然现在大多数笔记本电脑能装入公文包或者可象书包一样携带,但是离装入人们口袋的要求还差得很远.解决这个问题的根本途径是彻底放弃键盘,改用笔进行输入和操作,使之成为笔式电脑.笔式电脑是计算机发展的一个重要趋势.1991年,GRID公司推出笔操作系统,标志笔式电脑的诞生.随后各计算机软件公司竞相投入笔式电脑的开发.据预测,到1996年,英文笔式电脑将成为一种重要的机种,全球销量将达到500万台.笔式电脑的关键技术有微型化的硬件设备(除了不带键
With the further miniaturization of the microcomputer, a portable computer appeared and then a notebook computer appeared, but further miniaturization encountered difficulties because the size of the keys had to be the same as the size of the fingers, the fingers could not be reduced, and the keyboard naturally In fact, the current laptop can not be called a real “notebook.” Although most laptops can now be loaded into a briefcase or can be carried as a school bag, but also into the pocket of people’s requirements Far worse.To solve this problem is the fundamental way to completely abandon the keyboard, use the pen for input and operation, making it a pen-based computer.The pen computer is an important trend in computer development.In 1991, GRID company introduced pen operation System, marking the birth of pen-based computer .And then all computer software companies competing in the development of pen-based computer.It is predicted that by 1996, pen English computer will become an important model, the global sales will reach 5 million units. The key technologies for pen-based computers are miniaturized hardware devices (except without keys)
