Various Methods for Web and Device Integration

• HTTP Query + CGI
• Plugins
• Ajax
• HTML5 (HTML + JavaScript APIs)
• WebIntents

Method1: HTTP Query String + CGI

Server-side solution

e.g.) http://example.com/tv?channel=xxx&start_time=yyy&end_time=zzz&action=record

Method2: Plugins

Client-side solution using proprietary plugins

Method3: Ajax

Client-Server collaboration without plugins

Method4: HTML5 (HTML + JavaScript APIs)

Client-side solution + Server-side solution

Method5: WebIntents

Inter-application collaboration

Issues with the existing methods

Actual mechanism (CGI script, plugins, service APIs, etc.) vary from vendor to vendor, and there is a burden for developers.

• Difficulties with Defining APIs for Various Devices
• Difficulties with Integration of Distributed Services
• Difficulties with Dynamic Selection of Multiple Modalities

→ A standard mechanism is required so that people can develop systems regardless their skills.

Why not MMI?

Inter-modality collaboration using standard interfaces

Thanks!
