Text entry on handheld computers by older users

Abstract: Small pocket computers offer great potential in workplaces where mobility is needed to collect data or access reference information while carrying out tasks such as maintenance or customer support. This paper reports on three studies examining the hypothesis that data entry by older workers is easier when the pocket computer has a physical keyboard, albeit a small one, rather than a touch-screen keyboard. Using a counter-balanced, within-subjects design the accuracy and speed with which adults over 55 years of… Show more

“…Moderate exercise enhances the production of antioxidants (Evans, 2000), although very strenuous exercise or exercise in very frail older adults may impair immune function (Bruunsgard & Pedersen, 2000). Nonetheless, long-term exercise programs appear to enhance immunity, and those with better pulmonary function have fewer respiratory infections in later life (Kostka et al, 2000).…”

“…Communication is facilitated via the Internet because electronic mail allows greater flexibility in developing and maintaining personal relationships and because information can be acquired via the World Wide Web (Fox, 2001). There is certainly great potential, realized in notable cases such as SeniorNet (Ito et al, 2001), for the Internet to build social support and, while the impact on psychological well-being is an unresolved issue (Chen & Persson, 2002;Wright et al, 2000), many elders report that usage lets them transcend physical and economic limitations to mobility and increases cognitive activity (McMellon & Schiffman, 2002). As well, the future will undoubtedly involve a substantial role of the Internet for learning, job related or avocational, among older people (see .…”

“…Wright et al showed that adults over 55 years are significantly less accurate and slower when entering text via the touch-screen. 11 Even after additional practice FISCHER ET AL., Handheld Computing in Medicine 2002) with the touch-screen, many entries still contain errors. Recent advances in this field include the availability of portable keyboards and thumb keyboards.…”

“…However, most individuals with diabetes are aged over 50 (Winkley et al, 2013), and patients who are more frail and elderly may prefer the physical keyboard and large screen of a desktop computer (Office of Communications, 2011), partly due to usability problems associated with the small size of mobile devices, and declining motor abilities (Zhou et al, 2012). For example, text-entry using the on-screen keyboards on mobile devices requires fine pressure control, to avoid duplicate entries; Older people tend to press on-screen keys too heavily, and experience shaking hands, producing text errors (Wright et al, 2000). Thus, while desktop computer uptake has seen a 13% decline in young people since 2012, the falloff has been slower in DSN's may be required to provide indirect care (e.g., telephone or email advice on diet/weight control) to patients using ICTs (James et al, 2009, Peate, 2013.…”
