“…combat) that require the user to remain quiet, which makes it difficult to utter spoken commands. In addition, tasks such as drawing or target acquisition are not conducive to speech input control (Cleveland & McNinch, 1999). Other technologies such as eye-based control, gesture-based control, electromyography (EMG)-based control, and electroencephalograph (EEG)-based control have been developed to allow hands-free operation of a wearable computer (Calhoun et al, 1998).…”

Wearable computers allow users the freedom to work in any environment including hazardous environments that may require protective clothing. Past research has shown that protective clothing interferes with manual materials handling tasks, medical tasks, and manual dexterity tasks. However, little information exists regarding how protective clothing affects task performance with wearable input devices. As a result, a study was conducted to address this issue and offer recommendations to enhance the compatibility of chemical protective clothing and wearable input devices. Sixteen active-duty soldiers performed a text-entry task with a wearable mouse and touch pad, while bare handed, wearing 7-mil, 14-mil, and 25-mil chemical protective gloves, wearing a respirator alone, and wearing the respirator and each of three gloves. Upon completion of the experiment, participants rated task difficulty, confidence using the input device, and input device preference. Task completion times were 9% slower with the 25-mil glove than the 7-mil glove. Text entry was not perceived as difficult when bare handed, or wearing the 7-mil and 14-mil gloves, suggesting that thin chemical protective gloves (i.e. 7-mil and 14-mil) are more suitable than thicker gloves for use with wearable input devices. When using the touch pad, task completion times were 17% faster than when using the mouse. Subjective ratings of difficulty, confidence, and preference provide strong support for the use of a touch pad input device rather than a mouse.

“…Appropriate input modalities are fundamental to wearable interaction. Research in the field has explored hands-free input, such as gesture and speech recognition (Cleveland and McNinch, 1999;Broun and Campbell, 2001;Starner, 2002a,b;Lyons et al, 2004). Starner et al (2000) developed an infrared vision system in the form of a pendant in order to detect hand gestures performed in front of the body and used to control home automation systems.…”

“…Although advantageous in that the above modalities facilitate hands-free or hands-limited interaction with a wearable computer, they are not without their own individual limitations. The imprecise nature (Moore, 2013) of speech recognition software, users' language abilities (Witt and Morales Kluge, 2008;Shrawankar and Thakare, 2011;Hermansky, 2013), changes in voice tone (Hansen and Varadarajan, 2009;Boril and Hansen, 2010), and environmental demands affect voice recognition levels (Cleveland and McNinch, 1999;Mitra et al, 2012). Shneiderman (2000) states that speech interferes with cognitive tasks, such as problem solving and memory recall.…”

“…While recent products like Google Glass and Oculus Rift are responsible for popularizing the OHMD devices, the idea is not new. The Land Warrior system [12,19,48], developed by the U.S. army over the past decade, includes a heads-up eye display with an augmented reality visual overlay for soldier communication. Xybernaut Mobile Assistant [13] was a light-weight wearable computer system with a see-through head-mounted display with bright and clear picture.…”

The rapid increase in the use of wearable technologies, especially Optical Head-Mounted Display (OHMD) devices, suggests potentials for education and requires more scientific studies investigating such potentials. In particular, the issue of information access and delivery in classrooms can be of interest where multiple screens and objects of attention exist and can cause distraction, lack of focus and reduced efficiency. This study explores the usability of a single OHMD device, as an alternative to individual and big projected screens in a classroom situation.We developed OHMD-based prototypes that allowed presentation and practice of lesson material through three display and two control options. We conducted user studies to compare various feasible combinations using a series of evaluation criteria, including enjoyment, ability to focus, motivation, perceived efficiency, physical comfort, understandability, and relaxation. Our results did not strongly support a significant effect caused by the use of alternative displays. However, participants' feedback showed that they favoured OHMD as a single screen in classroom learning situations, while their main complaints about it were related to physical comfort and ease of control. Our studies also showed that participants were more pleased and motivated to learn when using OHMD. This suggests that improved OHMD technology will have the potential ability to be effective in classroom learning.iii
