Zhang, Ke, Jeng, Wei, Fofie, Francis, Pelechrinis, Konstantinos and Krishnamurthy, Prashant (2012): Towards reliable spatial information in LBSNs. In: Proceedings of the 2012 International Conference on Uniquitous Computing 2012. pp. 950-955.

The proliferation of Location-based Social Networks (LBSNs) has been rapid during the last year due to the number of novel services they can support. The main interaction between users in an LBSN is location sharing, which builds the spatial component of the system. The majority of the LBSNs make use of the notion of check-in, to enable users to volunteeringly share their whereabouts with their peers and the system. The flow of this spatial information is unidirectional and originates from the users' side. Given that currently there is no infrastructure in place for detecting fake checkins, the quality of the spatial information plane of an LBSN is solely based on the honesty of the users. In this paper, we seek to raise the awareness of the community for this problem, by identifying and discussing the effects of the presence of fake location information. We further present a preliminary design of a fake check-in detection scheme, based on location-proofs. Our initial simulation results show that if we do not consider the infrastructural constraints, location-proofs can form a viable technical solution.

Zhang, Shaopeng and Jeng, Wei (2011): Designing a public touchscreen display system for iSchool community. In: Proceedings of the 2011 iConference 2011. pp. 808-810.

This project aims to design and develop a public touchscreen display system for the School of Information Sciences at the University of Pittsburgh in order to provide research talks, events, announcements, job postings and other useful information to local community members. The motivation was to let students of the iSchool embrace information and experience technology in their daily environment and help them to understand the connection among people, information, and technology. Based on the project context and user requirements, target features were defined and design guidelines were formulated. A prototype was developed and then evaluated through usability testing and observation to validate the features and guidelines. Results showed that the system has met users' requirements and conforms to the context of the iSchool. This article provides some insights into designing a public touchscreen display system for educational institutions such as this iSchool.
