Context-Aware Information Provision to the Mobile Phone Standby Screen

Our context-aware information delivery system enables information to be provided directly to the standby screen of a user’s mobile phone. The information appears on the standby screen only while the user context matches the information context due to a function that continuously monitors the behavioral response to user context, time, location, and reference history. We conducted a four-month trial of local information provision with over 800 mobile phone users participating. Approximately 30% of them.. "positively accepted" this information provision and most users actually utilized the received information. This shows that our approach is effective for mobile ad delivery.
