Keyboard key arrangement method and hand-held electronic device using such method

Abstract

A keyboard key arrangement method and a hand-held electronic device using such a method are provided. The method is applied to a hand-held electronic device which has a touch screen, wherein the touch screen is capable of displaying a virtual keyboard. A user uses four fingers except for the thumb of each hand to hold the hand-held electronic device, and uses the two thumbs to touch and control the virtual keyboard for inputting data. The virtue keyboard key arrangement method first summarizes use frequency of each key on the virtual keyboard and generates a key use frequency chart, analyzes comfort indexes of the two thumbs of a user touching different key positions of the virtual keyboard and generates a comfort index chart, and finally arranges the virtual keys with relatively high use frequency at positions with relatively high comfort level on the virtual keyboard according to the key use frequency chart and the comfort index chart.

Description

technical field [0001] The invention relates to a method for arranging keys of a keyboard, in particular to a method for arranging keys of a keyboard applied to a handheld electronic device. Background technique [0002] Due to the vigorous development of mobile communication networks, the use of handheld electronic devices with mobile Internet access functions such as PDAs and smart phones is becoming more and more common. The advantage of using the handheld electronic device is that a large amount of data can be conveniently input into the handheld electronic device through a keyboard device provided by it, such as a virtual keyboard displayed on a touch screen or a physical keyboard. And if figure 1 As shown, the handheld electronic device 1, such as the arrangement of keys on the virtual keyboard 11 of the iPhone still follows the keyboard arrangement of the general desktop computer or notebook computer, but the keyboard arrangement of the general desktop computer or no...

Problems solved by technology

And if figure 1 As shown, the handheld electronic device 1, such as the arrangement of keys on the virtual keyboard 11 of the iPhone still follows the keyboard arrangement of the general desktop computer or notebook computer, but the keyboard arrangement of the general desktop computer or notebook computer It is designed according to the dexterity of the ten fingers of the user's hands and the frequency of use of the keys. However, the keyboard of a general handheld electronic device is much smaller than the keyboard of a general desktop computer or notebook computer, and the user uses two hands as large as the keyboard. The four fingers other than the thumb hold the handheld electronic device, and use the thumbs of both hands to tap the keyboard to input data, but the kinematics of the thumbs of both hands is very different from the kinematics of ten fingers. Thumbs are used to operate the keyboard designed according to the flexibility of ten fingers. It is easy to make the thumbs tired due to over-operation, and it is easy for the user to cause work injuries to the thumbs of both hands after long-term use.
