As IoT (Internet of Things) technologies and infrastructures become more mature, opportunities for engagement with representations of digital object memories (DOM) in the real world increase. Digital object memories can provide added value and pave the way for new consumer-oriented IoT products and services. However, our research experience of employing digital object memories in different systems for reminiscing, mediation of second-hand retail environments and augmenting digital heritage experiences (e.g. in museums) also point to some significant challenges as to how people can interact with DOMs in situ. Based on this work we will put forth some of the key user experience challenges that we encountered when employing representations of DOMs in the real world in the course of the last two and a half years and discuss some alternative routes we wish to explore through future research.
Metaphorically, altruistic acts, such as monetary donations, are said to be driven by the heart, whereas sound financial investments are guided by reason, embodied by the head. In a unique experiment, we tested the effects of these bodily metaphors using biofeedback and an incentivized economic decision-making paradigm. Participants played a repeated investment game with a simulated partner, alternating between tactical investor and altruistic investee. When making decisions, participants received counterbalanced visual feedback from their own or a simulated partner's heart or head, as well as no feedback. As investor, participants transferred a greater proportion of their endowments when exposed to visual feedback from their own head than to feedback from their own heart or no feedback at all. These effects were not observed when the source of the feedback was the simulated partner. As investee, heart feedback predicted greater altruistic returns than head or no feedback, but this effect did not differ based on source (own vs partner). Consistent with a dual-process framework, we suggest that people may be encouraged to invest more or be more altruistic when receiving bodily feedback from conceptually diametric sources.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
