CASY (by Zuckerman et al, 2005)
Contextual Asynchronous System (CASY) is a system that uses audio and video messaging, asynchronous communication and context-based delivery. CASY enables family members to send “good morning” and “good night” asynchronous video snippets into a shared family database. The recipient then views the snippets when going to sleep or waking up.
