It is universal that graphical user interface (GUI) applies to operating system or computer-generated imagery interface design. It indicates that most users have relied on a mouse to choose icons or selected boxes, while operating a computer. In most cases, when a user needs to repeat keying certain function keys, it means the working efficiency is low. To solve this problem, software designers normally set hot-key groups on the keyboard for work efficiency.
However, it might be a trouble for the ordinary people, because they need to memorize the hot-keys’ locations and functions. Given so, this research has focused on the application of augmented reality technology so that virtually visual digital information will be augmented and displayed on a real keyboard. It results in a better work efficiency by a better cognitive and memorized keyboard design.
Of this research, the conditions that the ordinary people use hot-key groups according to their age, sex, frequencies, learning and cognition were firstly analyzed. Afterwards, based on the guideline of User-Centered Design (UCD), the experimental augmented reality hot-key interface was designed. The finding reveals that a 28 to 30 percent of efficiency was increased on the subjects who seldom or never use hot-key groups. Moreover, the augmented reality (AR) hot-key interface effectively promotes the subjects’ learning performance, without particular memorizing. Virtually visual digital images stimulate the subjects’ cognitive ability.
Apart from raising the work efficiency on word processing, hot-key groups are also applied to graphic application software and the interface of on-line game operation as well. In the future, with the characteristics of augmented reality, the integration of human-computer interface could be employed in different users in diverse needs, so as to prompt the availability and popularity of hot-key groups.
