Unitless activity assessment and associated methods
A system assesses activity and displays a unitless activity value. A detector senses activity of a user. A processor reads sensed activity data from the detector. A display displays the unitless activity value. An enclosure houses the detector and the processor. The processor periodically reads the sensed activity data from the detector and processes the data to generate an activity number, the number being used to generate the unitless activity value based upon a maximum number and a display range.
1. A method of assessing usage by a user of an electronic system comprising a detector and a processor, the method comprising:
detecting, with the detector, use data indicative of use of the electronic system by the user during a use period;
processing, with the processor, the detected use data to determine a number representative of the detected use data during the use period; and
generating, with the processor, a value based on a comparison of the determined number and an expected maximum number for the use period.
2. The method of claim 1 , further comprising:
prior to the generating, identifying a type of activity of the user performed during the use period; and
prior to the generating, identifying the expected maximum number for the use period based on the identified type of activity.
3. The method of claim 2 , wherein the identifying the type of activity comprises detecting at least one press of a button.
4. The method of claim 2 , wherein the identifying the type of activity comprises processing at least a portion of the detected use data.
5. The method of claim 1 , further comprising presenting the generated value to the user.
6. The method of claim 5 , further comprising repeating the detecting, the processing, the generating, and the presenting for a plurality of consecutive use periods.
7. The method of claim 1 , further comprising repeating the detecting, the processing, and the generating for a plurality of consecutive activity periods.
8. The method of claim 1 , wherein the processing the detected use data to determine the number comprises integrating power spectral density of acceleration data of the detected use data over the period of time of the use period.
9. The method of claim 1 , wherein the use period is at least eight hours.
10. The method of claim 1 , wherein the detected use data is indicative of a number of physical repetitions.
11. The method of claim 1 , wherein the value is based on an intensity of the use of the user during the use period.
12. The method of claim 1 , wherein the value is based on a length of the use period.
13. The method of claim 1 , wherein the detected use data is indicative of at least two different activities.
14. The method of claim 1 , wherein the generating the value comprises:
determining a ratio based on the comparison of the determined number and the expected maximum number for the use period; and
multiplying the determined ratio by a range number.
15. A system comprising:
a detector configured to detect movement data indicative of movement over a movement duration of time; and
a processor configured to:
determine a number representative of the detected movement data over the movement duration of time; and
generate a value based on the determined number and a maximum number for the movement duration of time.
16. The system of claim 15 , further comprising an enclosure that at least partially houses each one of the detector and the processor.
17. The system of claim 16 , wherein the enclosure is configured to be worn on a wrist of a user during the movement duration of time.
18. A method of assessing data, comprising:
detecting data;
sampling the detected data during a time period;
processing the sampled data to determine a number representative of the sampled data for the time period;
adding the number to an accumulator number to provide an updated accumulator number; and
determining a value based upon the updated accumulator number and an expected maximum number, wherein the determining the value comprises:
determining a ratio based on a comparison of the updated accumulator number and the expected maximum number; and
multiplying the determined ratio by a range number.
19. The method of claim 18 , further comprising presenting the determined value to a user.
20. The method of claim 18 , wherein the detected data is indicative of a number of physical repetitions.
