Title:
POSTURE DETERMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/002494
Kind Code:
A1
Abstract:
Disclosed is a posture determination device that can easily determine posture without complicated calculations. Acceleration compositions (Gx to Gz) in normalized first to third axes directions output from a three-axis acceleration sensor (1) are input into first to third judgment units (5 to 9). The first judgment unit (5) judges which of the following ranges the first axis direction component (Gx) is in: Gx< -0.5, -0.5≦Gx<0, 0≦Gx<0.5, or 0.5≦Gx. The second judgment unit (7) judges which of the following ranges the second axis direction component (Gy) is in: Gy< -0.5, -0.5≦Gy<0, 0≦Gy<0.5, or 0.5≦Gy. The third judgment unit (9) judges which of the following ranges the third axis direction component (Gz) is in: Gz< -0.5, -0.5≦Gz<0, 0≦Gz<0.5, or 0.5≦Gz. Outputs from the first to third judgment units (5 to 9) are input into the posture determination unit (11) and the posture determination unit (11) judges the posture of a supporting body to which the three-axis acceleration sensor (1) is fixed.
