He could still calculate a rough angle with this (between horizontal and vertical) albeit with decreasing resolution as the sensor approaches 1g. He couldn't distinguish between pitch and roll (if there is such a thing for a cane) but I don't think it matters for this application. Just need to know if it's horizontal, vertical or somewhere in between with coarse accuracy. In one situation you'll be measuring ~1g, in the other ~0g. | |
