Desk Buddy will include a security measure to alert me and surrounding office if it is picked up. It will be powered by USB plug pack with a backup battery. If it is moved, a motion sensor will trigger a process that sends a push notification to the connected app and sounds a built in alarm. The battery will ensure it can continue to operate even when unplugged.
When I arrive in the office, a beacon will be detected by the app to then notify Desk Buddy. Desk Buddy will then know to initiate any sequences such as a greetings, flashing with "excitement" that I'm here.
A sensor may also be used to detect if someone is sitting at my desk when I'm not in so that Desk Buddy can switch to Visitor mode.
