Measuring hand, head, and vehicle motions in commuting environments

Viewing video on mobile devices is becoming increasingly common. The small field-of-view and the vibrations in common commuting environments present challenges (hardware and software) for the imaging community. By monitoring the vibration of the display, it could be possible to stabilize an image on the display by shifting a portion of a large image with the display (a field-of-view expansion approach). However, the image should not be shifted exactly per display motion because eye movements have a 'self-adjustment' ability to partially or completely compensate for external motions that can make a perfect compensation appear to overshoot. In this work, accelerometers were used to measure the motion of a range of vehicles, and observers' heads and hands as they rode in those vehicles to support the development of display motion compensation algorithms.
