Two commonly used keypad arrangements are the telephone and calculator layouts. The purpose of this study was to determine if entering different types of numeric information was quicker and more accurate with the telephone or the calculator layout on a computer keyboard numeric keypad. Fifty-seven participants saw a 10-digit numeric stimulus to type with a computer number keypad as quickly and as accurately as possible. Stimuli were presented in either a numerical [1,234,567,890] or phone [(123) 456-7890] format. The results indicated that participants' memory of the layout for the arrangement of keys on a telephone was significantly better than the layout of a calculator. In addition, the results showed that participants were more accurate when entering stimuli using the calculator keypad layout. Critically, participants' response times showed an interaction of stimulus format and keypad layout: participants were specifically slowed when entering numeric stimuli using a telephone keypad layout. Responses made using the middle row of keys were faster and more accurate than responses using the top and bottom row of keys. Implications for keypad design and cell phone usage are discussed.
两种常用的小键盘布局是电话和计算器布局。本研究旨在确定在计算机键盘数字小键盘上，使用电话或计算器布局输入不同类型的数字信息是否更快、更准确。57 名参与者看到了一个 10 位数字的刺激，他们尽可能快、尽可能准确地用计算机数字小键盘输入。刺激以数字[1,234,567,890]或电话[(123)456-7890]格式呈现。结果表明，参与者对电话上按键排列布局的记忆明显优于计算器的布局。此外，结果还表明，参与者在使用计算器小键盘布局输入刺激时更加准确。关键的是，参与者的反应时间显示了刺激格式和小键盘布局的相互作用：当使用电话小键盘布局输入数字刺激时，参与者的反应速度明显减慢。使用中间行的键进行的响应比使用顶部和底部行的键进行的响应更快、更准确。讨论了对小键盘设计和手机使用的影响。
