| Â | Suggestion of navigation function (position, direction, distance) |
|---|---|
A | It is difficult to decide the superiority or inferiority of guidance by the clock position and eight directions. |
B | The distance to the destination was found well. |

D | It should support, when a direction of movement changes quickly (ex; the obstacle, bump to a person). |
E | I would like to always check whether it is walking correctly to a course. |
F | I was not able to memorize guidance to the destination, however I have imagined it. |
