## Abstract

An exercise system includes an exercise machine and an exercise handle coupled to the exercise machine via a cable, the exercise handle comprising a set of sensors. The set of sensors is used to detect a location of a portion of a user's hand on the exercise handle.

## Claims

### Claim 1

An exercise system, comprising:
an exercise machine; and
an exercise handle coupled to the exercise machine via a cable, the exercise handle comprising a set of sensors;
wherein the set of sensors is used to detect:
a location of a thumb of a user's hand on the exercise handle and an orientation of the exercise handle; and
an observed pressure mapping; and
wherein whether a right hand or a left hand of the user is holding the exercise handle is determined, by a processor, based at least in part on:
the detected location of the thumb of the user's hand on the exercise handle and the orientation of the exercise handle; and
a comparison of the observed pressure mapping against an expected pressure mapping, wherein the expected pressure mapping is associated with a particular exercise movement.

### Claim 2 (depends on 1)

The exercise system of claim 1, wherein the set of sensors is used to detect one or more digits on the exercise handle, and wherein a digit in the one or more digits is identified as the thumb.

### Claim 3 (depends on 2)

The exercise system of claim 2, wherein the digit is identified as the thumb at least in part by determining an orientation of the digit relative to an orientation of another digit.

### Claim 4 (depends on 2)

The exercise system of claim 2, wherein the digit is identified as the thumb at least in part by determining an end point of the digit relative to an end point of another digit.

### Claim 5 (depends on 1)

The exercise system of claim 1, wherein the set of sensors is used to detect a location of a palm on the exercise handle.

### Claim 6 (depends on 1)

The exercise system of claim 1, wherein the processor is configured to determine whether the user is facing toward or facing away from the exercise machine.

### Claim 7 (depends on 1)

The exercise system of claim 1, wherein the expected pressure mapping is associated with a particular hand.

### Claim 8 (depends on 1)

The exercise system of claim 1, wherein the exercise machine comprises a first arm on a first side and a second arm on a second side, and wherein the exercise handle is coupled to the first arm.

### Claim 9 (depends on 1)

The exercise system of claim 1, wherein the set of sensors comprises a set of capacitive sensors.

### Claim 10 (depends on 1)

The exercise system of claim 1, wherein the exercise handle comprises pressure sensitive gel, and wherein the set of sensors is used to detect the location of the thumb of the user's hand on the exercise handle at least in part by detecting a location of pressure applied on the pressure sensitive gel.
