Query: A study of posture judgement on vehicles using wearable acceleration
  sensor   We study methods to estimate drivers' posture in vehicles using acceleration
data of wearable sensor and conduct field tests. To prevent fatal accidents,
demands for safety management of bus and taxi are high. However, acceleration
of vehicles is added to wearable sensor in vehicles. Therefore, we study
methods to estimate driving posture using acceleration data acquired from shirt
type wearable sensor hitoe and conduct field tests.
