The Human-Computer Interaction lab of University of California, Santa Cruz is seeking participants to beta-test EmotiCal, a new, unique technology to improve well-being. EmotiCal provides analytics regarding what factors seem to most impact your mood and how your mood is expected to change over time. We are seeking pre-release beta-testers to try EmotiCal and give us feedback on what they like or dislike. This beta-test is entirely online. Participation begins mid-end October and is only for 13 days. This is an exciting opportunity to contribute to well-being research and in addition you may also enter a raffle for a $50 Amazon.com gift card for your participation.
