While walking meetings offer a healthy alternative to sit-down meetings, they also pose practical challenges. Taking notes is difficult while walking, which limits the potential of walking meetings. To address this, we designed the Walking Talking Stick---a tangible device with integrated voice recording, transcription, and a physical highlighting button to facilitate note-taking during walking meetings. We investigated our system in a three-condition between-subjects user study with thirty pairs of participants (N=60) who conducted 15-minute outdoor walking meetings. Participants either used clip-on microphones, the prototype without the button, or the prototype with the highlighting button. We found that the tangible device increased task focus, and the physical highlighting button facilitated turn-taking and resulted in more useful notes. Our work demonstrates how interactive artifacts can incentivize users to hold meetings in motion and enhance conversation dynamics. We contribute insights for future systems which support conducting work tasks in mobile environments
Social awkwardness is a frequent challenge to healthy social interactions and can dramatically impact how people feel, communicate and behave. It is known that humor can invoke positive feelings and enable people to modify perspective of a situation. We explored whether using a non-humanoid robotic object performing humorous behavior can reduce social awkwardness between two strangers. The robot was peripherally incorporated into the interaction to ensure the natural social flow. We compared the impact of humorous and non-humorous robotic gestures on the human-human interaction. Objective and subjective measures indicate that despite being peripheral to the human-human interaction, the humorous robotic gestures significantly reduced the intensity of awkwardness between the strangers. Our findings suggest humorous robotic behavior can be used to enhance interpersonal relationships hindered by awkwardness and still preserve natural human-human interaction.
“Libraries of Things” are tangible collections of borrowable objects. There are many benefits to Libraries of Things such as making objects and skill-building accessible, reducing waste through the sharing of items, and saving costs associated with purchasing rarely-used items. We introduce the first HCI study of Library of Things by interviewing 23 librarians who run a variety of collections such as handheld tools, gear, and musical instruments – within public institutions and more grass-roots efforts in the private sector. In our findings, we discuss the challenges these collections experience in changing behavioural patterns from buying to borrowing, helping individuals `try new things', iterating to find sharable items, training staff, and manual intervention throughout the borrowing cycle. We present 5 opportunities for HCI research to support interactive skill-sharing, self-borrowing, maintenance recognition and cataloguing `things', organizing non-uniform inventories, and creating public-awareness. Further in-the-wild studies should also consider the tensions between the values of these organizations and low-cost convenient usage.
As the world becomes more interconnected, physical separation between people increases.
Existing collaborative Virtual Reality (VR) applications, designed to bridge this distance, are not yet sufficient in providing a sense of social connection comparable to face-to-face interactions.
Possible reasons are the limited multimodality of VR systems and the lack of non-verbal cues in VR avatars.
We systematically investigated how facial expressions influence Social Presence in two collaborative VR tasks.
We explored four types of facial expressions: eyes and mouth movements, their combination, and no expressions, for two types of explanations: verbal and graphical.
To examine how these expressions influence Social Presence, we conducted a controlled VR experiment (N = 48), in which participants had to explain a specific term to their counterpart.
Our results demonstrate that eye and mouth movements positively influence Social Presence in VR.
Particularly, combining verbal explanations and eye movements induces the highest feeling of co-presence.
Automatic stress tracking has become increasingly available on wearable devices. Research has investigated its use for individual stress management, largely within the traditional data-as-care framing. However, its use for stress sharing in social relationships, particularly close relationships, is still under explored. Inspired by the idea of "caring-through-data", which focuses on mediating the social and emotional experiences of the collective "us" with data, this paper presents a design study with a prototype called IntimaSea, a display featuring illustrative stress data in collective forms to be shared among close relationships. The field trials with nine groups of intimately-connected users (N=19) highlight its potential on stress awareness, interpretation and management, as well as intimacy promotion. We end by discussing sharing stress for social ways of stress management, stress data as a meaningful social cue mediating relationships, as well as design implications for caring-through-data.
We conducted 26 co-design interviews with 50 smarthome device owners to understand the perceived benefits, drawbacks, and design considerations for developing a smarthome system that facilitates co-monitoring with emergency contacts who live outside of one's home. Participants felt that such a system would help ensure their personal safety, safeguard from material loss, and give them peace of mind by ensuring quick response and verifying potential threats. However, they also expressed concerns regarding privacy, overburdening others, and other potential threats, such as unauthorized access and security breaches. To alleviate these concerns, participants designed flexible and granular access control and fail-safe back-up features. Our study reveals why peer-based co-monitoring of smarthomes for emergencies may be beneficial but also difficult to implement. Based on the insights gained from our study, we provide recommendations for designing technologies that facilitate such co-monitoring while mitigating its risks.
