Wearable Travel Aid using the Navigation map for the acquired visually impaired

将楼梯等的位置信息添加到通道的导航地图支持视障者安全行走。可穿戴的旅行援助估计位置使用地图和多个传感器。提出了一种新的位置估计指标，用于根据周围环境和情况的变化确定位置估计值。该指数的可靠性得到了澄清。实验结果表明，楼层估计是有效的位置估计。

The navigation map which added the position information on stairs etc. to the passage supports a visually impaired safe a walk. Wearable travel aid is estimated position using the map and multi sensors. The new index was proposed for determining an estimated position in response to changes circumference environment and situation. A reliability of the index was clarified. Experimental results show that floor estimation is useful for the position estimation.
