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

将楼梯等位置信息添加到通道中的导航地图支持视障人士的安全行走。可穿戴式旅行辅助设备使用地图和多个传感器来估计位置。新的指数是为了根据周长、环境和情况的变化确定估计位置而提出的。阐明了该指数的可靠性。实验结果表明，该方法对位置估计有较好的效果。

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.
