“…By definition, wearable computers are used in environments that differ dramatically from the normal domains of computer use. They can be exposed to outside environmental conditions, connected to Gobal Positioning System for location awareness, and connected to wireless local area networks for transmission of digital data (Ockerman, Najjar, and Thompson, 1997). At a recent conference, Mann, 1998 presented what he believed to be a significant difference between wearable computers and other portable computing devices.…”

Since the introduction of graphical user interfaces (GUIs), input control devices have become an integral part of desktop computing. When interfacing with GUIs, these input control devices have become the human's primary means of communicating with the computer. Although there have been a number experiments conducted on pointing devices for desktop machine, there is little research on pointing devices for wearable computer technology. This is surprising because pointing devices are a major component of a wearable computer system, allowing the wearer to select and manipulate objects on the screen. The design of these pointing devices will have a major impact on the ease with which the operator can interact with information being displayed (Card, English, & Burr, 1978). As a result, this research is the first in a series to investigate design considerations for pointing devices and visual displays that will support wearable computer users. Twenty soldiers participated in an experiment using target acquisition software with five pointing devices and two visual displays. The findings of the research strongly support the use of a relative modepointing device with rotational characteristics (i.e., trackball or thumbwheel) over other designs. Furthermore, the results also suggest that there is little difference between pointing devices operated with the thumb and index finger for target acquisition tasks. This study has also showed that there were few differences in pointing and homing time for pointing devices across the two visual displays. Finally, the study demonstrated that the Fitts law model could be applied to hand-operated pointing devices for wearable computers. This is important because it allows the future development of pointing devices to be compared with the devices tested in this research using the Fitts Law Index of Performance calculations.

“…Earlier, wearable displays were rarely used beyond the experimental stage (Baudhuin, ; Caudell & Mizell, ; Neumann & Majoros, ; Ockerman, Najjar, & Thompson, ; Ong, Yuan, & Nee, ; Randell, ; Tang, Owen, Biocca, & Mou, ). However, the functionality, usability, and design of wearable displays have improved remarkably in recent years, and thus, they can be applied in practical situations.…”

This study analyses the behavioral, physiological, and psychological effects of digital manuals presented by a retinal imaging display (RID) on workers in the manufacturing industry. An RID consists of wearable glasses that enable users to view a digital image overlaying the real world. We conducted an experiment in which subjects assembled an object by referring to different types of manuals. The experimental results suggest that an RID enables users to conveniently examine real objects against information in the manual, reduces the information‐processing load while performing tasks, and supports effortless performance of tasks. However, using a monochrome picture manual with an RID increases the information‐processing load. On the other hand, a full‐color RID movie manual generates additional responses in users, such as psychological satisfaction.
