A system includes a sensor device configured to detect a touch pressure dependent characteristic of a body part of a user while the user touches a touch surface with the body part. The system also includes an image capture device configured to capture an image of the body part of the user while the user touches the touch surface. The system further includes a processor configured to associate the image with an amount of pressure exerted on the touch surface by the user. The processor is also configured to compare the amount of pressure exerted on the touch surface to a desired amount of pressure associated with the user for the sensor device, and initiate compensation for the touch pressure dependent characteristic based upon the comparison.

The smart phone as recited in claim 1, further comprising an indicator configured to provide the instruction to move the body part to the user. 5. The smart phone as recited in claim 1, wherein the touch pressure dependent characteristic of the user comprises at least one of an oxygen saturation, a glucose concentration, a carbon monoxide (CO) concentration, or a carbon dioxide (CO2) concentration associated with blood in the body part of the user. 6. A smart phone comprising: a smart phone camera for capturing images of a surrounding environment;a sensor device including a light source and a light sensor, the sensor device disposed under a touch surface adjacent to the smart phone camera, the sensor device configured to detect a touch pressure dependent characteristic of a body part of a user while the user touches the touch surface with the body part, the smart phone camera configured to capture a partial image of the body part of the user while the user touches the touch surface with the body part and the touch pressure dependent characteristic is detected;anda processor configured to associate the partial image with an amount of pressure exerted on the touch surface by the user, compare the amount of pressure exerted on the touch surface by the user to a desired amount of pressure associated with the user for the sensor device, and initiate compensation for the touch pressure dependent characteristic based upon the comparison. 7. The smart phone as recited in claim 6, wherein initiating compensation for the touch pressure dependent characteristic comprises initiating an instruction to move the body part to adjust the amount of pressure exerted on the touch surface by the user toward the desired amount of pressure associated with the user for the sensor device. 8. The smart phone as recited in claim 6, wherein initiating compensation for the touch pressure dependent characteristic comprises modifying a signal that measures the touch pressure dependent characteristic. 9. The smart phone as recited in claim 8, wherein modifying the signal that measures the touch pressure dependent characteristic comprises discarding data comprising at least a portion of the signal. 10. The smart phone as recited in claim 8, wherein modifying the signal that measures the touch pressure dependent characteristic comprises removing an artifact from the signal. 11. The smart phone as recited in claim 6, wherein the partial image is associated with the amount of pressure exerted on the touch surface by determining an area of the touch surface pressed by the body part. 12. The smart phone as recited in claim 6, further comprising an indicator configured to provide the instruction to move the body part to the user. 13. A method comprising: capturing, by a smart phone camera for capturing images of a surrounding environment, a partial image of a user;detecting, by a sensor device including a light source and a light sensor, the sensor device disposed under a touch surface adjacent to the smart phone camera, a touch pressure dependent characteristic of a body part of a user while the user touches the touch surface with the body part, the partial image of the user including a partial image of the body part of the user captured while the user touches the touch surface with the body part and the touch pressure dependent characteristic is detected;associating the partial image with an amount of pressure exerted on the touch surface by the user;comparing the amount of pressure exerted on the touch surface by the user to a desired amount of pressure associated with the user; andinitiating compensation for the touch pressure dependent characteristic based upon the comparison. 14. The method as recited in claim 13, wherein initiating compensation for the touch pressure dependent characteristic comprises initiating an instruction to move the body part to adjust the amount of pressure exerted on the touch surface by the user toward the desired amount of pressure associated with the user. 15. The method as recited in claim 13, wherein initiating compensation for the touch pressure dependent characteristic comprises modifying a signal that measures the touch pressure dependent characteristic. 16. The method as recited in claim 15, wherein modifying the signal that measures the touch pressure dependent characteristic comprises discarding data comprising at least a portion of the signal. 17. The method as recited in claim 15, wherein modifying the signal that measures the touch pressure dependent characteristic comprises removing an artifact from the signal. 18. The method as recited in claim 13, wherein the partial image is associated with the amount of pressure exerted on the touch surface by determining an area of the touch surface pressed by the body part.
