10.8 The tactile arrow will announce the next decision point Left and
Right early with a double movement Left of Right (pre warning).
The tactile arrow will turn back to 12.00 h, the DP is not reached
yet.
10.9 Pre warnings are given at about 30 meter before the actual
decision point, dependent on the GPS signal. This is far enough to
prepare yourself for the coming directional change, f.e. to cross the
street.
10.10 Close to the decision point, the definitive command is given by
which the tactile arrow turns and stays in the desired direction for
10 seconds. A ‘Go Straight’ command is given if the tactile arrow
moves short left and right and back to 12.00 h.
10.11 Spoken commands will accompany the tactile arrow. (Go Left, Go
Right, Go Straight)
10.12 Tactile and spoken commands will be given as close to the
decision point as possible but preferably not too late. I-Cane built in
a safety margin
– needed for the inaccuracy of GPS – by which the
instructions could be given before the actual DP.
10.13 Multiple directional commands must be carried out in the given
order. You have to memorize them.
10.14 The tactile arrow is not helping you to make the correct turn of to
cross safely. Use your mobility skills
– cane use, orientation,
echolocation, traffic sounds, pedestrian crossings and public help
–
to walk on to the next DP. In complex situations you may neglect
the tactile arrow and rely on your own perception.
10.15 The final turn of the tactile arrow will be abandoned after 10
seconds, regardless if you turned into the new direction or street. A
spoken message will tell you about the distance to the next
decision point/ This is helpful to decide if you want to cross the
street sooner of later.
10.16 This procedure is repeated at any following decision point. You will
learn by doing and the initial uncertainty will be limited. Your safety
on the sidewalks and during crossing asks for attention at all time.
The Mobilo looks as a standard white cane by which public and
traffic will respond to as usual. Stay alert and use your knowledge
and experience with traffic situations. You remain responsible for
you own safety, also by using the Mobilo.
