Smart Home products enable the elderly to enjoy life in a healthy, safe, and comfortable way and provide families and healthcare service providers with more convenient and efficient care tools for the elderly. However, making the elderly willing to adopt Smart Home products will be the primary issue for product designers, family members, and health care service providers. This study used the senior technology acceptance model (STAM) and designed a theoretical model to discuss the relationships among gerontechnology self-efficacy, gerontechnology anxiety, cognitive abilities, perceived usefulness, perceived ease of use, and behavioral intentions with structural equation models. Respondents of the present study were mainly the elderly in Taipei Min-sheng Community Center, and seniors studying in the EMBA program of National Taiwan University of Science and Technology and National Taipei University who are over 56 years old. Paper-based and online questionnaires were distributed, and a total of 222 questionnaires were collected. The LISREL results indicated that the statistics showed a good fit (χ2 /df = 2.31, GFI = 0.85, AGFI = 0.81, NFI = 0.97, NNFI = 0.98, CFI = 0.98, and RMSEA = 0.07) and all hypotheses were supported by the path analysis results. Based on the findings, theoretical and managerial implications, as well as suggestions for future research were provided in this study.
