P r o j e c t s :  P o r t a l

Interactive installation consisting of multiple video projections displaying time-based media (videos) whose behaviour (timing, order, volume, editing) can be controlled through motion. Motion is used as a ‘natural’ interface that allows users of multiple levels of computer/mobile literacy to access content. The user will be able to control the video behaviour with a modified Wii controller (first prototype) or SunSpot sensor (second prototype), camera-phone (third prototype) or other
Bluetooth-enabled devices (future prototype).

Iterations:

1. Play/Stop video: allow control of playback through manipulation of accelerometer sensor

2. Edit between videos: switch between simultaneously running video streams

3. Slow down playback: affect video stream to create slow-motion effect and/or reverse playback (enabling user to ‘scrub’ or search video for desired location)

4. Volume control: affect volume of one stream over another

5. Multi-screen control: affect streams on located on multiple screens

6. Future iterations:

• Implement high-resolution accelerometer support (SunSpot sensor)
• Implement camera-phone gyroscopic program to control video

Overall Architecture:

1. User affects the playback of a wall of video projects (or other display) using either a Wii controller, a custom-built controller (SunSpot), or a camera-phone.

2. User with either Wii controller or custom-built controller will not require special software to control the installation.

3. User with camera-phone will need to download camera-gyroscope application to control the installation.

4. User’s movements are translated into x, y, z coordinates of 3D space. These measurements are mapped onto corresponding control actions (play, stop, source A/B, volume, reverse, etc.)

5. Bluetooth server receives data broadcasted by controller and creates a patch to the video controller software on one or multiple computer/projector units.
