On the Choice and Placement of Wearable Vision Sensors

This paper discusses two of the most important design considerations for a wearable device with visual sensing: what kind of sensor to use and where to place it. While nature and computer vision have explored a wide range of imaging techniques, wearables have mostly viewed the world through conventional narrow-view passive cameras designed for nonwearable applications, which are attached to the wearer´s head. The rationale presented here for sensor selection and the novel methodology developed for objectively studying sensor placement have informed the development of a number of visual wearables.
