Researchers in Human–Computer Interaction (HCI) have long developed technologies for older adults. Recently, researchers are engaging in critical reflections of these approaches. IoT for aging in place is one area around which these conflicting discourses have converged, likely in part driven by government and industry interest. This article introduces diffractive analysis as an approach that examines difference to yield new empirical understandings about our methods and the topics we study. We constructed three analyses of a dataset collected at an IoT design workshop and then conducted a diffractive analysis. We present themes from this analysis regarding the ways that participants are inscribed in our research, considerations related to transferability and novelty between work centered on older adults and other work, and insights about methodologies. Our discussion contributes implications for researchers to form teams and account for their roles in research, as well as recommendations how diffractive analysis can support other research agendas.

Abstract Optimal aging in place has become a common preference among older adults to maintain identity and independence, thus smart home technologies are increasingly utilized to achieve these goals. However, disconnect may exist between potential technological benefit and perceptions of acceptability and usability (Lee & Coughlin, 2015). We assessed perceptions of adults aged 50+ (range 50-90 years) to analyze their priorities and ultimate acceptability of smart home technology. Data were collected through surveys, focus groups, and case study interviews. Three major themes emerged regarding smart home utilization: benefits, concerns, and expectations. Participants endorsed smart home technologies (e.g., sensors, telehealth devices) and identified benefits, such as the promotion of optimal aging (e.g., maintaining independence, staying active, safety). However, responses also reflected concerns about privacy, ease of use, and amount of control. Expectations regarding smart homes included more mobility, efficiency, and safety within the home. One participant described technology as having “options [that] are exhausting, but also exciting.” Survey responses (n=30) were analyzed to understand participants’ familiarity with smart home technologies, including: nanotechnology (10.7%), smart showers (42.9%), home sensors (70.4%), telehealth (74.1%), smart appliances (71.4%), personal sensors (81.5%), and voice-activated devices (96.4%). Additionally, respondents indicated their willingness to implement these technologies to maintain and/or improve their daily functioning: nanotechnology (53.8%), smart showers (28.6%), home sensors (66.6%), telehealth (81.5%), smart appliances (40.0%), personal sensors (55.5%), voice-activated devices (64.3%). Discussion focuses on the priorities and needs older adults express regarding technology utilization and the implications for person-centered design and implementation of future smart home technologies.

FEATURE AT A GLANCE: In this article, we examine the interplay between electronic voting technology machine types (touchscreen vs. touchscreen + keypad) and ballot designs (full ballot vs. one office per page) that together comprise the interface to which voters are exposed. Using a gerontological approach, we show that determining the most usable system for voters with the most limited capabilities (in this study, older participants) also corresponded to higher performance across groups (younger participants). Because older adults are more sensitive to slight differences in human-computer interaction designs, examining their performance may help shed light on potential problems that could otherwise go undetected.

Bertambahnya warga Gereja secara terus-menerus menyebabkan pertambahan data yang cukupsignifikan pada Gereja-Gereja, baik itu data jemaat, datakeuangan dan data-data lainnya. Arus informasi keuanganGereja sangat dibutuhkan untuk mengetahuiperkembangan Gereja dari sisi finansial, bagaimanastruktur modal, berapa pemasukan dan pengeluaran padasatu periode tertentu. Pengelolaan data keuangan diGMIM Wilayah Tomohon 3 masih dilakukan dengan caramanual yang kurang efektif dan efiesien sehinggamenyebabkan tidak maksimalnya proses pengelolaan datayang ada. Oleh karena itu dibuatlah sebuah aplikasi WebService Sistem Informasi Keuangan GMIM Wilayah 3untuk mengatasi permasalahan pengelolaan data keuanganyang ada.Metode pembuatan aplikasi ini menggunakan metodeperancangan sistem Rapid Application Development (RAD),yang dimulai dengan tahap analisis persyaratan yangdilakukan dengan membuat problem statement matrix.Tahap selanjutnya, design workshop (pemodelan)digambarkan dengan proses bisnis, structural model danbehavioral model, serta human computer interaction layerdesign. Tahap terakhir, implementasi (konstruksi)dijelaskan dengan implementasi basis data dan kodesumber program.Kata Kunci : Gereja, Rapid Application Development(RAD), Sistem Informasi Keuangan, Web Service

According to User-Centered Design, computer interactive systems should be implemented taking into account the users’ preferences. However, in some cases, it is not easy to apply conventional Human-Computer interaction evaluation techniques to identify the users’ needs and improve the user-system interaction. Therefore, this chapter proposes a procedure to model the interaction behaviour from the analysis of conversational agent dialog logs. A case study in which the procedure has been applied to model the behaviour of 20 children when interacting with multiple personality Pedagogic Conversational Agents is described as an illustrative sample of the goodness and practical application of the procedure.

This paper demonstrates that work domain analysis (WDA), a cognitive engineering approach based on Rasmussen's abstraction hierarchy (AH) framework, is a valuable and alternate analytic tool for analyzing human-computer interaction (HCI) in complex work domains through a case study. In the case study, we use WDA to examine automation awareness, an HCI issue in automated flight decks. The case study shows that WDA provides an effective approach to systematically assess collected human factors data in order to identify the gaps in satisfying the work requirements across interrelated factors. It helps assess the adequacy of domain information provided to workers via training in order to build a fairly accurate and effective mental model, adequacy of domain information presented to workers at the interface, and the adequacy of operation procedures designed for workers to copy with unfamiliar situations. Finally, WDA also helps generate needs for enhancements of existing systems from a work domain perspective.
