Biosensing hardware is just now starting to appear in the tech hardware space, with mainstream products like the Fitbit allowing users to better understand their lifestyle. However, few if any hardware products have tackled the most impactful and relatable data in a user's day: human emotion.
Our mission was two-fold - to create a tool for logging and understanding the user's emotions throughout the day, and to document the user's day using a camera triggered by significant emotional changes. We use both a Galvanic Skin Response (GSR) meter and a pulse-oximeter detector, which provide data that tracks the user's excitement remarkably well. Our device can detect, for instance, if the user has been asked an emotional question or if they are thinking about something distressing, on the order of seconds.
While this data is being recorded, our device also scans for periods when the user's emotions are particularly intense or changing at a rapid rate, and at key moments sends a trigger to an external camera which snaps a picture of what the user is experiencing at that moment. At the end of the day, the user has an album of notable events during the day, even if they did not remember consciously to chronicle them at the time.
