Why intelligent interaction on mobile
- Everyone has one or more mobile
- It contains many useful private
- Relatively small screen size,
difficult input interface, and limited computational power
- Increase of multimedia data (photo,
mp3, movie files) on the mobile device
The goals of this research are as
- Developing synthetic characters for
- Prediction of users' behavior based
on the information on the mobile device (call logs, location, short
- Context-awareness on mobile device
- Efficient summarization and
searching of multimedia data on the mobile device
2. Proposed Methods
- Developing software for gathering
information on the mobile device
- Estimation of high-level context
from the low-level sources using probabilistic models (Bayesian
- Detection of chances and keys from
huge information using key graph and Bayesian networks
- Reorganization of personal
experience and multimedia data for efficient search (semantic
search) using semantic network
- Prediction of user's future
location using recurrent Self-organizing map and Markov model
- Behavior generation of synthetic
characters on the phone using behavior network and rule-based action
- Implementation on real PDA devices

3. Experimental Results
- Demonstration of synthetic
- Demonstration of location-aware
