Abstract
Handheld computing systems or devices can be defined as exceptionally portable, independent information management and communication devices. Furthermore, handheld computing systems or devices can be seen as a small or pocket-sized computing device with a touch screen keyboard and input and output interface. According to the definition of handheld computing systems, numerous devices fit the description such as smartphones, personal digital assistants (PDAs) and pagers. However, adult first- time users of computer systems face different issues in adopting the device and the literature reviewed shows that most of them have difficulties with the design, such as the touch screen. The negative views of technology devices by adult first-time users can be attributed to the difficulty in adapting to new technology. Weakness, incapacity, distrust of technology, absence of perceived value and trouble in understanding how to utilise the device are largely the main problems observed by adult first-time users of handheld computer systems. However, they could accept the use of the devices provided their needs are taken into consideration by the developers. The limitation of the research was that only adults in the age range of 55 to 91 in Gauteng in South Africa were chosen for this research.
