title = "Adaptive power control of obstacle avoidance system using via motion context for visually impaired person",
abstract = "We propose adaptive power control of obstacle avoidance system for visually impaired person. It utilizes multiple ultrasonic sensors to avoid obstacles lying in the path. We evaluate complex structure in front of the user with predefined patterns and determine avoidance direction by analysing those patterns. It controls the number of active ultrasonic sensors by evaluating motion context using built-in accelerometer sensor. Our system safely guides visually impaired person as well as adaptively control power consumption of mobile devices.",
