Usage modes

You can use iWalkStraight in two ways.

Hold in hand

“hold in hand”. Run iWalkStraight and hold your iPhone in one hand. When you tap twice anywhere on the screen, iWalkStraight starts monitoring your direction. If you rotate too much towards right, iWalkStraight tells you to rotate on the left (reads “left”). Analogously, if you rotate too much on the left, iWalkStraight reads “right”. Pay attention: iWalkStraight only knows how where your iPhone is pointing. Hence it is important that the hand holding the iPhone moves together with your body. For example, we suggest to keep your hand on your belly. When you want iWalkStraight to stop talking, tap twice anywhere on the screen.

Hold in your pocket

Run iWalkStraight and put your iPhone (without locking it) in your pants pocket. When you get to a point where you need to walk straight, hit your pocket. You will hear iWalkStraight telling you “OK”. From now on, iWalkStraight checks that you walk straight and will suggest you to turn right or left. When you reach your destination, hit your pocket again and iWalkStraight will stop talking.

User preferences

In the option menu (that can be found in your iPhone “Settings” app), you can set the following preferences.

  • Hit sensitivity. Pay attention: if you set a light hit, iWalkStraight might activate or stop unintentionally.
  • Angle tolerance: while you walk, iWalkStraight tells you to rotate if you rotate more than this agle from the starting position. For example, if the tolerance angle is 9 degress (this is the default value), iWalkStraight will suggest you to correct you direction if you rotate more than 9 degrees. You can set a smaller value to be even more precise. Pay attention: small values might result in iWalkStraight frequently correcting your direction and this might be annoying.
  • Talking delay: iWalkStraight will not warn you immediately when you rotate more than the “angle tolerance”. Indeed, it might happen that, when you walk, your body rotates for a while and then goes back to the right direction. For example, with its default value, iWalkStraight warns you only if your angle is above the tolerance angle for half a second. If your direction is “wrong” for less than half a second, iWalkStraight will not disturb you. You can choose a smaller value to be even more precise in your walk but pay attention: smaller values might result in iWalkStraight to correct your direction very often and this might be annoying.
