• Control panels of current appliances are difficult to use.
• Wireless remote controllers are hard to find, easy to lost.
• As services disappear, controlling them might be more difficult.
• People must remember too many mappings between controllers and appliances.

Motivation - TUI and Universal Remote Controller
• Tangible User Interfaces• Physical form to digital information
• Pros: easy to recognize and use• Cons: hard to deploy and reconfigure

Pebbles (CMU)
• Universal Controller Architecture• One personal device as a universal controller
• Pros: easy to deploy and reconfigure• Cons: hard to recognize and use

Challenges
HardwareDeveloper
•Size•Weight•Power Consumption•etc.
ServiceProvider•Deployability
•Scalability•Reusability•High level API•etc.
User
•Simple Interaction Style•Usability•etc.

Design Issues• Deployability and Scalability
• Deploy anytime, anywhere• Update or replace easily and cheaply
• Reusability and High level abstraction• Deal with high level user events
• Simple interaction style• Easy to use• Short setting up time

Approaches• Mobile code
• Download controlling software automatically from those services to improve deployability
• Visual tag and Service mapping• Weak mappings between tags and services’ code impro
ve deployability• Visual tag is representation of invisible service
• Controlling using real world interaction• Provides high level sensor API• Reinforces augmented reality
• Simple interaction cycle• Defines three interaction stages
• Searching, Selecting, Using

Evaluation and Discussion• Average size of each mobile code: 14KB• Latency of mobile code migration: less than 419ms
• Divided attention between controllers and services
• Which view a user should look?• The feedback view on the
personal device?• The application view?

Conclusion• We proposed Vidgets which is a research for
interaction design and building framework that seamlessly integrates personal devices and pervasive services
• We implemented a prototype system that confirms the effectiveness of our framework.
[Future work]• Detailed user studies (for developers, users)• Deal with some issues
• Divided attention• Security risks in mobile code
• Cell phone / PDA implementations
