Multipurpose contacts for delivering electro-haptic feedback to a wearer

摘要

Wearable devices are described herein including a housing and a mount configured to mount the housing to an external surface of a wearer. The wearable devices further include first and second electrical contacts protruding from the housing and configured such that the electrical contacts can be used to measure a Galvanic skin resistance of skin proximate to the electrical contacts when the wearable device is mounted to the external surface of the wearer. The electrical contacts are additionally configured to deliver an electro-haptic stimulus to skin proximate to the electrical contacts when the wearable device is mounted to the external surface of the wearer. Electro-haptic stimulus could be delivered to a wearer to indicate information to the wearer, including information about a health or activity state of the wearer, about communications received by the wearable device, and about alerts generated by the wearable device.

主权项

1. A wearable device, comprising:
a housing; a mount configured to mount the housing to an external body surface; first and second electrical contacts protruding from the housing, wherein the first and second electrical contacts are configured to contact skin at the external body surface when the housing is mounted on the external body surface such that a Galvanic skin resistance (GSR) of the skin at the external body surface can be measured between the first and second electrical contacts and such that an electro-haptic stimulus can be delivered to the skin at the external body surface using the first and second electrical contacts; and electronics disposed in the wearable device, wherein the electronics comprises:
a GSR sensor electronically coupled to the first and second electrical contacts and configured to obtain a measurement relating to the GSR of the skin at the external body surface; andan electro-haptic stimulator electronically coupled to the first and second electrical contacts and configured to deliver an electro-haptic stimulus to the skin at the external body surface.
