Abstract

A method and system for assisting a user in maintaining a predetermined pace along a track with a specific predetermined end goal. The preferred embodiment uses a PDA or similar device to allow a user set a specific course goal and to enter (or download) a previous profile pace target along with checkpoint data for a specified track, detecting start/stop and checkpoints along a course, normalizing the user time at each checkpoint and providing wireless speech ‘behind/ahead’ feedback (either time or energy) to a user at each checkpoint along a specified track. The present invention may provide the user with a variable pace along a track or course utilizing upcoming terrain, percentage of work completed and/or user power profiles and may normalize a user goal to other competitors having faster or slower track times.

Claims

1. A method to facilitate physical training, the method comprising the steps of:

having a user wear a GPS logging device which includes a user output interface;

having the user travel through a race course;

automatically logging a plurality of waypoints along the race course;

entering into the GPS logging device a checkpoint interval based either on a time interval or a distance interval;

having the user select a finishing goal time and entering it into the GPS logging device;

having the user travel through the race course a second time;

automatically logging a plurality of waypoints along the race course for the second travel through the race course;

receiving from the GPS logging device at the check-point interval, a calculated delta indicating a comparison between the user'"'"'s first and second elapsed time or distance histories during the user'"'"'s second travel through the race course;

receiving from the GPS logging device at each of the checkpoint intervals a signal indicating how far ahead or behind the user is at that position based on the finishing goal time during the user'"'"'s second travel through the race course calculated using the following normalization algorithm;

a. calculating a (first interpolated time) at the checkpoint interval through the process of selecting the closest two positions to the current position from the elapsed time history of the first travel through the race course and using the two positions to interpolate what the user'"'"'s first time was at the user'"'"'s current position;

b. calculating a Delta1 comprising a difference between the user'"'"'s first total elapsed time for the course and the finishing goal time;

c. calculating a percentage of work completed using the formula;

(first interpolated time)/(user'"'"'s first total elapsed time for the course)

d. calculating a Delta2 comprising the formula;

(percentage of work completed)×

(Delta1)

e. adding Delta2 to the (first interpolated time) to get a target time (Tc)

f. comparing the elapsed time at the current checkpoint to Tc to determine the time the user is behind or ahead of the goal time; and

g. notifying the user of being time “

behind”

or time “

ahead”

at the current checkpoint.

2. The method of claim 1 further comprising the steps of uploading the first elapsed time history to a web site;

a) next downloading to the GPS logging device an elapsed time history of the first user, then comparing a second user'"'"'s travel through the race course to the downloaded history of the first user;

b) using the normalization algorithm of claim 1 adjusting the first elapsed time histories for display to the second user; and

c) uploading the second elapsed time histories to the website.

3. The method of claim 1 further comprising the steps of notifying the user of being distance “

ahead”

or distance “

behind”

using the following steps;

a. using the normalization algorithm of claim 1 for determining the time “

ahead”

or “

behind”

at a checkpoint interval;

b. calculating a first interpolated time at the checkpoint interval through the process of selecting the closest two positions to the current position from the elapsed time history of the first travel through the race course and using the two positions to interpolate what the user'"'"'s first time was at the user'"'"'s current position;

c. if the user is “

ahead”

at a checkpoint, subtract the time ahead from the first interpolated time to get the target time (Tt);

if the user is “

behind”

at the checkpoint, add the time behind to the (first interpolated time) to get the target time (Tt);

d. calculating an interpolated position through the process of selecting the closest two times to the target time (Tt) from the elapsed time history of the first travel through the race course;

e. calculating the distance from the interpolated position to the current position along the path taken defined by the elapsed time history of the first travel through the race course; and

f. notifying the user of being distance “

behind”

or distance “

ahead”

at the current checkpoint.
