Device and method for displaying track characteristics
First Claim
1. A portable GPS unit comprising:
- a GPS receiver for receiving satellite signals from a plurality of satellites;
a processor coupled with the GPS receiver for calculating a location of the GPS unit as a function of the satellite signals; and
a display, coupled with the processor, for displaying a single track display which itself indicates both a user'"'"'s recent and present location and a track characteristic representing at least one feature sensed by at least one sensor, wherein the track characteristic of the track display varies in response to a change in the feature as sensed by the sensor.

Abstract
A portable, handheld GPS unit (10) is operable to generate a track log corresponding a track traversed by a user and display a track display representative of the track traversed. The track display includes at least one track characteristic indicative of a feature sensed by at least one sensor (26) coupled with the GPS unit (10). The track characteristic of the track display varies in response to a change in the feature sensed by the sensor. For example, the track display may display a track of varying width, such that an increase in the track'"'"'s width corresponds to an increase in the feature, and a decrease in the track'"'"'s width corresponds to a decrease in the feature. Alternatively, the characteristic may be a track color change or a symbol indicating a predetermined amount change in the feature. The sensed feature may include altitude, distance, heart rate, temperature, light intensity, and oxygen content. In a first preferred embodiment, the sensor (26) is an altimeter (26) for determining an altitude of the GPS unit (10). In a second preferred embodiment, the sensor (126) is a sonar transducer (126) for determining a depth of a body of water. In a third preferred embodiment, the sensor (226) is a heart rate monitor (226)for determining a heart rate of the user. Additionally, the GPS unit (10) may be combined with a plurality of sensors (26, 126,226) for determining and displaying an indication of multiple features sensed by the sensors (26, 126,226).
