Student-led organizations for computing are becoming more commonplace in large universities, ranging from chapters of larger organizations such as the Society of Women Engineers or the ACM Student Chapter to campus-based local groups. However, student organizations dedicated to computing education remain uncommon. Compared to existing resources such as computing-focused clubs, TA training, and research seminars, a computing education-focused organization offers peer-to-peer pedagogical training and education-focused resources so that members are conscientious of both the way that computing is taught and their own positionality in the field.

Integrating cameras into wireless smart rings has been challenging due to size and power constraints. We introduce IRIS, the first wireless vision-enabled smart ring system for smart home interactions. Equipped with a camera, Bluetooth radio, inertial measurement unit (IMU), and an onboard battery, IRIS meets the small size, weight, and power (SWaP) requirements for ring devices. IRIS is context-aware, adapting its gesture set to the detected device, and can last for 16-24 hours on a single charge. IRIS leverages the scene semantics to achieve instance-level device recognition. In a study involving 23 participants, IRIS consistently outpaced voice commands, with a higher proportion of participants expressing a preference for IRIS over voice commands regarding toggling a device’s state, granular control, and social acceptability. Our work pushes the boundary of what is possible with ring form-factor devices, addressing system challenges and opening up novel interaction capabilities.
