The document describes a GPS visual speedometer that uses special glasses connected to a heart rate monitor. The user presets a desired heart rate or speed. A floating line then appears in front of the user during their run or bike ride to help them visually track their performance. If a speed was preset, the line moves at a constant pace - if the user passes it they are going too fast, and if it moves ahead they are too slow. If a heart rate was chosen, the line's speed varies with the terrain to match the user's target rate.

1. GPS VISUAL SPEEDOMETER
At the start of the training, the user pre-sets a desired hart-rate (e.g. 140 bps) or speed (e.g. 12 km/h).
By means of special (sun) glasses connected (e.g. by small wire or wifi) to the hart rate monitor, a
floating line will appear in front of the user during the training. This floating line will lead the way and
allow the user to visually keep track of her/his performance during the training.
If a speed was pre-set, this line will move at a constant speed, starting at 5 meters in front of the exact
GPS position of the runner. If the runner goes too quickly, he/she will overtake the floating line. If
she/he goes too slow, the floating line will go further and further away in front of her/him.
Should a hart-rate have been defined at the start, then the speed of this line will obviously vary with the
profile (e.g. hills) of the run. In this case, a permanent communication with the hart rate monitor device
is required to put the floating line at the right place.
