Home Computing Software Infrastructure
Future home computing applications need to support context-awareness. accessing various Web services. composing multiple home appliances. Flexible user interface. → It is important to provide high level abstraction for building home computing applications easily.
Overview of Our Home Computing Software Infrastructure
Middleware for home automation Provide high level abstraction → We have implemented HAVi-based middleware.
Middleware for user interface management Provide flexible user interface management → We have implemented user interface management middleware supporting various interaction devices.

Experiences
HAVi is too heavy to used for embedded devices.
We are working on more light-weighted Web-based middleware
The middleware will be able to add context-awareness to existing UPnP or Web based home appliances.
Commodity software is useful to build portable embedded software.
Embedded Linux and Java is very effective. But, we need a more flexible framework.
We are working on flexible customizable implementation of the above middleware.
