With our eWatch for data collection, even bus drivers and assembly workers can handle interruptions of their daily activities to answer questions about their stress. The eWatch is a multisensor platform containing a 3D accelerometer, microphone, light and temperature sensors, as well as pushbuttons, vibrator, and LCD screen. Combined with machine learning algorithms, eWatch technology can be used to automate the assessment of exposure to stress and activities of daily living. We explore different I/O channels, such as buttons, voice, tap, and gesture for input, and beep, vibration, LCD screen and LEDs for output. These new technologies may allow us to adapt our measurements more effectively to the activity requirements of daily life in order to reduce or even eliminate participant response demands associated with the real time assessment of stress.
