Good afternoon -
I need to measure the velocity of subjects walking and running along a walkway of 10+ meters. Our lab brainstorming has produced several ideas, and we would like to hear about your experiences with the methods below, and how well they meet the criteria below. Any other ideas are also welcome!
Thank you,
Dr. Angie Berg Robertson
Ideal criteria:
- simple
- wireless (i.e., subject not tethered)
- can cover 10 meters
- measurements can be recorded and saved/exported
- precision of 0.1 m/s or better at walk/run speeds
- can provide instantaneous velocity data (though averages would suffice)
- not affected by subject posture or sway
- can synchronize with other equipment
Ideas that meet some/most of the above criteria:
- accelerometer
- cameras
- ultrasonic positioning system (e.g., http://en.souvr.com/product/200712/274.html#facts)
- indoor GPS (e.g., http://www.polhemus.com/?page=Motion_Liberty_Latus)
- laser range finder
- tow-line
- speed gun
- light gates
- your suggestion!
