1. Mission-oriented Project A Platform for Location Aware Service with Human Computation, PLASH • Ling-Jyh Chen, Meng Chang Chen, Sheng-Wei Chen, Jan-Ming Ho, Wang-Chien Lee, Jane Liu, De-Nian Yang Presenter: Meng Chang Chen

2. Intelligent & Ubiquitous Computing Center Technical DevelopmentMobile Networking & CommunicationMultimedia Content Management Virtual infrastructure for interactive cloud app. Platforms PLASH Industrial Collaboration +

3. History of PLASH • Kicked off in August 2009 • Supported by NSC NCP office • Also supported by CITI & IIS • A 3-year project • Personnel • Ling-Jyh Chen, Meng Chang Chen, Sheng-Wei Chen, Jan-Ming Ho, Wang-Chien Lee, Jane Liu, De-Nian Yang • 10 -12 Research Assistants

4. Goals and Deliveries of PLASH • To provide a platform to allow voluntary users via “human computation games” to contribute their location-based observations/efforts so as to facilitate some difficult location aware tasks. • (Difficult location aware tasks) City profiling (surface traffic estimation, telecommunication network performance monitoring, city trend analysis) trip planning, spot locating, etc. • To explore novel technologies to support the location aware platform and applications. • Massive data mining, location-based query, image-assisting positioning, indoor positioning/tomography

5. Goals of PLASH (contd.) • To design a layered architecture to allow application builders to conveniently create their systems. • To provide a location-based dataset benchmark for various research • To build and transfer prototype to potential receivers. • To promote the use of wireless communications.

15. Progress of 1st Year • Literacy Enabling Web Service for Location-Aware Systems • Goal: to assist identifying location by using image • Geo-location Query Service • Goal: to provide on-line geo-location query service • Localized Data Dissemination in V2V networks • to develop a localized data dissemination scheme via exploiting the intermittent connectivity of vehicle networks. • Location-related Applications • Map N’Track Friends: let your friend know where your travel route • Itinerary recommendation: provide personalized route • Friend compass: indicate where a friend is

16. Future Work • Deployand operate the following applications • Track-a-friend: let your friend know where your travel route • Travel route recommendation: provide personalized route • Friend compass: indicate where a friend is • TAF (TO and FRO) • Innovative enabling technologies and applications • Location-aware user experience summarization using comic Maps • Road anomaly detection using smart phones • Moving object clustering • City Profiling • Understanding the service performance of carriers • Surface traffic estimation • Allow volunteers to build their application by using provided APIs on PLASH. Could be SaaS or PaaS.
