Abstract
Smart house technology using tablet computers may help older people to master activities of daily living by making it easier to perform daily tasks like controlling lights and indoor temperature throughout the house with a few keystrokes. The aim of this study was to investigate the impact of age, cognition, self-efficacy, and technology experience on the ability of older people to perceive and use iPad tablet computers for this purpose. Twenty-eight participants were interviewed using a structured interview guide and questionnaires, and a practical test of how to use the iPad was performed. The Mini-Mental State Examination (MMSE) was used to assess cognition. Cognitive deficits and low self-efficacy significantly reduced the ability of the subjects to use the smart house technology and to perceive the smart house technology service as provided. Age was unrelated to the outcome variables. Finally, technology experience had an effect on technology perception. If further research supports these findings, it should influence smart-house implementation in an elderly population, raising awareness of usability problems in older people with low self-efficacy and cognitive problems.
