Pao, Sheng-Ying, Mota, Selene, Chung, Keywon and Reben, Alexander (2012): A need-driven design approach: addressing latent needs in collaboration rooted in early childhood. In: Proceedings of ACM CSCW12 Conference on Computer-Supported Cooperative Work 2012. pp. 829-832.

When the latent needs are un-addressed, collaboration can be easily turned into a non-collaborative activity while the participants are unaware of why. This paper describes a need-driven approach for computer-supported collaborative interaction design, with specific focus on collaboration rooted in early childhood. We conducted a need-identification study, where explicit needs and latent needs in children's collaborative interaction were identified and constructed into a guideline for computer-supported collaboration design. Demonstrating the need-driven approach, a toolkit was designed and the prototype was evaluated based upon the guideline attempting to address the needs identified. The need-driven approach and the design guideline that the toolkit design was based upon may offer new dynamic domains for future computer-supported collaboration design.

Chung, Keywon, Shilman, Michael, Merrill, Chris and Ishii, Hiroshi (2010): OnObject: gestural play with tagged everyday objects. In: Proceedings of the 2010 ACM Symposium on User Interface Software and Technology 2010. pp. 379-380.

Many Tangible User Interface (TUI) systems employ sensor-equipped physical objects. However they do not easily scale to users' actual environments; most everyday objects lack the necessary hardware, and modification requires hardware and software development by skilled individuals. This limits TUI creation by end users, resulting in inflexible interfaces in which the mapping of sensor input and output events cannot be easily modified reflecting the end user's wishes and circumstances. We introduce OnObject, a small device worn on the hand, which can program physical objects to respond to a set of gestural triggers. Users attach RFID tags to situated objects, grab them by the tag, and program their responses to grab, release, shake, swing, and thrust gestures using a built-in button and a microphone. In this paper, we demonstrate how novice end users including preschool children can instantly create engaging gestural object interfaces with sound feedback from toys, drawings, or clay.

Chi, Pei-Yu, Xiao, Xiao, Chung, Keywon and Chiu, Carnaven (2009): Burn your memory away: one-time use video capture and storage device to encourage memory appreciation. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2397-2406.

Although modern ease of access to technology enables many of us to obsessively document our lives, much of the captured digital content is often disregarded and forgotten on storage devices, with no concerns of cost or decay. Can we design technology that helps people better appreciate captured memories? What would people do if they only had one more chance to relive past memories? In this paper, we present a prototype design, PY-ROM, a matchstick-like video recording and storage device that burns itself away after being used. This encourages designers to consider lifecycles and human-computer relationships by integrating physical properties into digitally augmenting everyday objects.

Chung, Keywon, Chiu, Carnaven, Xiao, Xiao and Chi, Pei-Yu (Peggy) (2009): Stress outsourced: a haptic social network via crowdsourcing. In: Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009. pp. 2439-2448.

Stress OutSourced (SOS) is a peer-to-peer network that allows anonymous users to send each other therapeutic massages to relieve stress. By applying the emerging concept of crowdsourcing to haptic therapy, SOS brings physical and affective dimensions to our already networked lifestyle while preserving the privacy of its members. This paper first describes the system, its three unique design choices regarding privacy model, combining mobility and scalability, and affective communication for an impersonal crowd, and contrasts them with other efforts in their respective areas. Finally, this paper describes future work and opportunities in the area of haptic social networks.
