Psychosocial Indicators via Hand Tremor

We propose hand tremor as a new type of input that can corroborate psychosocial conditions An Android application was able to distinguish tremor variability differences between people with and without diagnosed hand tremor. Tremor measurements also corroborated self-assessment of sleep quality. Hand tremor evaluation can be considered to be a monitorable, implicit input to systems that respond to various psychosocial states. We encourage researchers to consider how interface design changes when using implicit sensors such as tremor sensing.
