Abstract-The convergence of Internet and mobile devices has radically changed the way people communicate and interact with each other, and demand for applications that are "social" enough to assist their daily interactions. To support such device mediated interactions, the social relationships between actors need to be systematically modeled and represented. In addition, an application facilitating such interactions should be able to deal with the task conflicts that occur when an actor is involved in multiple interactions simultaneously. To address these issues, in this paper we present an approach to modeling and coordinating social interactions with the notion of social context. It supports social interaction modeling from both the domain-and player-centric perspectives. In particular, the player-centric model provides the basis to coordinate multiple interactions in which an actor is involved. We further introduce a fuzzy logic based reasoning technique to infer the overall importance of each interaction, assisting the actor to resolve conflicts and make decisions. Finally, we validate our approach through a prototype implementation and test cases analysis.

Abstract. We present the design and evaluation of Panoramic, a tool that enables end-users to specify and verify an important family of complex location events. Our approach aims to reduce or eliminate critical barriers to deployment of emerging location-aware business activity monitoring applications in domains like hospitals and office buildings. Panoramic does not require users to write code, understand complex models, perform elaborate demonstrations, generate test location traces, or blindly trust deterministic events. Instead, it allows end-users to specify and edit complex events with a visual language that embodies natural concepts of space and time. It also takes a novel approach to verification, in which events are extracted from historical sensor data traces and then presented with intelligible, hierarchical visualizations that represent uncertainty with probabilities. We build on our existing software for specifying and detecting events while enhancing it in non-trivial ways to facilitate event specification and verification. Our design is guided by a formative study with 12 non-programmers. We also use location traces from a building-scale radio frequency identification (RFID) deployment in a qualitative evaluation of Panoramic with 10 non-programmers. The results show that end-users can both understand and verify the behavior of complex location event specifications using Panoramic.

“…What can be done to overcome these potentially negative aspects? One suggestion is to provide more information to the user so they know what the system is doing or about to do and why it is doing so (Bellotti and Edwards, 2001). This could involve designing additional kinds of system feedback.…”

A framework for designing sensor-based interactions to promote exploration and reflection in play

Sensor-based interactions are increasingly being used in the design of user experiences, ranging from the activation of controls to the delivery of 'context-aware' information in the home. The benefits of doing so include the ability to deliver relevant information to people at appropriate times and to enable 'hands-free' control. A downside, however, is that sensor control often displaces user control, resulting in the user not knowing how to or being able to control aspects of a system. While this can be frustrating in many situations, it provides new opportunities for enhancing or augmenting various kinds of activities, where uncertainty can be exploited to good effect. We describe how we designed an adventure game for young children that incorporated a number of sensor-based interactions. We also present a preliminary conceptual framework intended to help designers and researchers develop novel user experiences using sensor-based interactions. A set of concepts are provided that characterize salient aspects of the user experience involved in sensing together with a discussion of the core properties of sensor technologies.
