Ambient Glance

Ambient Glance is program powering an ambient information display based on a LD220-HP POS pole display (normally used in the context of a retail Point Of Sale). Ambient Glance features a driver for the display, a TUI mirror used for development/debugging, individual "apps" that can be shown, and a scheduler supporting both an automatic carousel between apps and preemption.

The following apps are implemented today:

  • Clock
  • Fortune - based on the fortune(6) command
  • 8 clap - The UCLA 8 clap
  • ADS-B - to display the closest detected aircraft within a small radius of a receiver
  • OneBusAway - Transit arrival data

This is not an officially supported Google product. This project is not eligible for the Google Open Source Software Vulnerability Rewards Program.
