Summary

Provide enhanced switch support for onBoard. This allows you to enter text and navigate the Gnome desktop using a single (or more) switch input device.

Rationale

Some users cannot use a normal mouse or keyboard but only a single switch operated by light touch, air pressure, etc. onBoard currently has very basic support for entering text via switch operation, but the potential is much greater.

Use cases

• Simon uses a single switch to operate his computer. When properly configured he can surf the web, write emails and send commands to his X-10-based environmental control system, to turn on lights, open doors and windows.

Scope

• Desktop navigation using AT-SPI
  • GOK reads widget information from an application and displays it on-screen within GOK, which can me controlled by switch input. An alternative approach is to perform operations directly on the host application the way at-poke does.
• Enhanced switch input methods including configurable scanning sequences and multiple switches.
  • Investigate what the 2-3 most efficient input methods are for 1 and two switches and implement those.

Unresolved issues
