Personal Universal Controllers:Controlling Complex Appliances with GUIs and Speech

CHI 2003 Conference on Human Factors in Computing Systems Ft. Lauderdale, Florida

Jeffrey Nichols Conference on Human Factors in Computing Systems (CHI) April 8, 2003 � � �Slide #2

The Problem

Appliances are too complex

Jeffrey Nichols Conference on Human Factors in Computing Systems (CHI) April 8, 2003 � � �Slide #3

The Problem, cont.

Each complex appliance has its own idiosyncratic interface!•Home and Car Stereos•VCRs & Camcorders•Car Navigation Systems•Answering Machines•…

Increasingly Computerized Low Usability

Jeffrey Nichols Conference on Human Factors in Computing Systems (CHI) April 8, 2003 � � �Slide #4

Our Solution

Separate the interface from the appliance!

Handheld becomes personal universal controller (PUC)Key Features

User interface-independent appliance specification Automatic generation of GUI and speech interfaces

Specifications

Control

Feedback

Automatic Generation of UIs

Benefits All interfaces consistent for the user

With conventions of handheldOther applications and UI guidelines

Even from multiple manufacturersAddresses idiosyncracy problem!

Multiple modalities (GUI + Speech UI)

Can take into account user preferences

Will work on special purpose devices (for disabled)

Future Work Improve quality of generated user interfaces

More and better rules

Specification and generation of more appliances answering machine, navigation system

Consistent interface generation New interfaces modeled on past interfaces

Generating interfaces for the “experience” One interface generated for multiple connected

appliances

General purpose appliance adaptor for HAVi and UPnP protocols
