Abstract. The main purpose of research presented in this paper is to create a simplified senior shopping typology utilizing a values-based segmentation approach. This typology is then used to see whether and how certain segment's characteristics may influence the usage of and willingness-to-adopt mobile devices related to shopping tasks. Understanding the way senior consumers shop and how pervasive mobile services can meet their needs is important to help build applications and devices which can enhance seniors' quality of life. The research presented in this paper examines the relationship between the willingness-to-adopt mobile devices on the part of senior consumers (i.e. +65) and the relative ease they experience during shopping.

To date, there has been limited research carried out to better understand seniors' needs and purchase motivations related to mobile devices. To that end, this research enabled an exploratory assessment of the intrinsic and extrinsic needs/motives to consider in future research and development of ubiquitous mobile devices and related applications, specifically for seniors. The 65+ population is expected to double by 2025 (WHO, 2013) from 390 million to 800 million. The results demonstrate specific needs/motives which should be considered during the development of new mobile attributes and apps for this segment. For both attributes of devices themselves and the applications found on them, three tiers of priority for development were determined.

Introduction: The senior population is projected to continue to increase dramatically for the foreseeable future and cognitive issues associated with aging have become a major concern as they affect people's ability to carry on activities of daily living. One area of daily living, which has often been cited as a key problem area for seniors is the detection of risks in the home, especially in the kitchen. The kitchen is the place where most domestic accidents occur and the oven is the main source. Methods: We propose a safety kitchen solution, InOvUS, which focuses on safety and reducing the risk of fire, burn and intoxication. We present the evaluation of the soundness of the method we designed to evaluate the adoption intention and interest of a safety kitchen system from a senior user's perspective. Results: We develop a conceptual model utilizing several existing scales such as the CAI (consumer adoption intention), CI (consumer innovativeness), TAM (technology acceptance model), PEOU (perceived ease of use) and PU (perceived usefulness) scales, but specific to the senior 65+ segment. Conclusion: The evaluation results of InOvUS through the application of our model show a clear buying intention toward InOvUS and also a clear intent to use it.
