Where do you rate the application w.r.t the concept2. Where do you rate the application w.r.t the interface3. Where do you rate the application w.r.t the functionality4. Rate your experience with the application5. Would you like to use the application in futureUser StudyBox PlotUser Study (cont’d)ability to delete the abilities/friends. ability to import contacts from social apps (like facebook). a mobile friendly interface (besides a browser interface). support for non-exact match for the abilities and the one requested by a user. support for pictures of the users. visual/sound indication for a user logging in/outUser Study (cont’d)Great potential exists for location aware social networkingGet help in real-time from near-by users for small physical tasks – novel ideaExtend the social circle to include friend-of-friends – yet to be exploitedOpens door to several possibilities – recommendation of places, context based tagging, collaborative content…..Conclusionpredict next destination from the logged user traces. Data mining and Machine Learning, in suggesting places to visit. Previous works such as [1] have demontrated that learning collaboratively in a social setting is possible and improves performance. Host on Google Apps. Some higher constructs like Natural Language processing for performing non-exact match on the abilities and help item. Have the application run in off-line mode via Google Gears. Develop an iPhone App, that would allow insight into more user-experienceFuture WorkThanks, for your attentionAny
