半QWERTY是一种新的单手打字技术，旨在促进双手打字技能转移到单手条件下，它是在标准键盘（修改软件）或特殊的半键盘（全尺寸键）上进行的。实验表明[2]，使用半QWERTY技术，QWERTY触摸打字员可以在相对较短的时间内（<10小时）实现高单手打字率（40+ wpm）。这些速度是使用紧凑型键盘可实现的速度的2-3倍，并且超过手写速度。半QWERTY键盘在为残疾用户提供访问和设计紧凑型计算机方面非常重要。关键研发：输入设备，输入任务，人的表现，单手键盘，QWERTY，便携式计算机，残疾人用户，技能转移。是什么？这个交互式体验展示展示了一种新的单手文本输入方法，该方法利用了双手打字中已经开发的技能。它被称为“半QWERTY”，因为它只使用了QWERTY键盘的一半。该技术可用于标准QWERTY键盘（仅使用一半可用键，图1）或特殊的半键盘（图2），前者提供了广泛的技术访问。例如，后者提供了具有支持便携式计算机上的触摸键入的全尺寸键的紧凑键盘。允许免费复制本材料的全部或部分内容。es不是为d制作或分发的！rect GwnrnerGI@ advantage，ACM cvpyr，right notice和出版物的ttle及其日期出现，ncmce IS given that copy！ng是由计算机协会的perm{sston}编写的。复制或再版，需要付费和/或特别许可。CH 194 Companion-4/94 Boston，马萨诸塞州USA e 1994 ACM 0-89791-651-4/94/0051。..$ 3.50 William Buxton University of多伦多& Xerox PARC c/o Computer SystemLsResearch Institute University of多伦多多伦多，安大略，加拿大M5 S 1A 4（416）978-1961 buxton@dgp.toronto.edu它是如何工作的？*半QWERTY键盘由一只手在标准QWERTY键盘上打字时使用的所有键组成，另一只手的键未使用或不存在。打字手的键像以前一样打字。要键入缺少的手的字符，用户只需按住空格键，并执行以前由缺少的手完成的手指移动（图1）。因此，使用空格键作为修饰符，打字员可以仅用一只手生成填充大小的键盘两侧的字符。它将如何使用？例如，当执行需要在键盘和鼠标文本编辑之间频繁切换的任务时，半QWERTY特别有用。可以用一只手输入文本，用另一只手选择和操作项目。由于两只手都处于各自任务的“原位”，因此在设备之间移动时不会浪费时间[1]。此外，通过在标准键盘上实现半QWERTY，人们可以轻松地在这种类型的输入和双手打字之间切换。最后，因为当空格键被按下时，键盘的每一侧都映射到另一侧，所以用户可以选择用哪只手来单手打字。实际上，用户可以在一个键盘中选择三个键盘：双手QWERTY键盘和两个半QWERTY键盘，每只手一个。佩戴而不是携带的计算机对于“实地”数据收集具有显著优势。通过消除不经常使用的密钥（例如，数字键）和减小空格键的尺寸，一个Half-QWERTY键盘可以做得足够小，可以戴在惯用手的手腕上（图2）。当LCD屏幕戴在另一只手腕上时，由此产生的打字姿势允许用户同时打字和查看显示器。l正在申请专利。1991年3月21日公开的国际申请号PCTICA 90100274，国际公开号W 091/03782。
Half-QWERTY is a new one-handed typing technique, designed to facilitate the transfer of two-handed typing skill to the one-handed condition, It is performed on a standard keyboard (with modified software), or a special half keyboard (with full-sized keys). Experiments have shown [2] that it is possible for QWERTY touch-typists to achieve high one-handed typing rates (40+ wpm) in a relatively short period of time (<10 hr) using the HalfQWERTY technique. These speeds are 2-3 times the rates achievable using compact keyboards, and exceed handwriting speeds. Half-QWERTY is important in providing access to disabled users, and for the design of compact computers. KEY WO R D S: Input devices, input tasks, human performance, one-handed keyboard, QWERTY, portable computers, disabled users, skill transfer. WHAT IS IT? This Interactive Experience display demonstrates a new approach to one-handed text entry which exploits the skills already developed in two-handed typing. It is called, “HalfQWERTY,” because it uses only half of the QWERTY keyboard. The technique can be used on a standard QWERTY keyboard (using only half of the available keys, Figure 1), or with a special half keyboard (Figure 2), The former provides wide access to the technique. The latter provides a compact keyboard with full-sized keys supporting touch typing on portable computers, for example.

Keys of the typing hand are typed as before. To type characters of the missing hand, the user simply holds down the space bar and performs the finger movement previously done by the missing hand (Figure 1). Thus, using the space bar as a modifier, a typist can generate the characters of either side of a fill-sized keyboard, using only one hand. HOW WILL IT BE USED? Half-QWERTY is especially useful when performing tasks which require frequent switching between keyboard and mouse—text editing, for example. Text can be entered with one hand, and items selected and manipulated with the other. Since both hands are in “home position” for their respective task, no time is lost in moving between devices [1]. Furthermore, by implementing Half-QWERTY on a standard keyboard, one can ea~sily switch between this type of input and two-handed typing. Finally, since each side clf the keyboard is mapped onto the other side when the space bar is depressed, the user can choose which hand to use fcr one-handed typing. In effect, the user has a choice of three keyboards in one: a two-handed QWERTY keyboard, and two Half-QWERTY keyboards, one for each hand. A computer that is worn, rather than carried, has significant advantages for data collection “in the field.” By eliminating infrequently used keys (e.g., the number keys) and reducing the size of the space bar, a Ha’lf-QWERTY keyboard can be made small enough to wear on the wrist of the dominant hand (Figure 2). With an LCD screen worn on the other wrist, the resulting typing posture allows the user to type and view the display, simultaneously. lPatents pending.
