Transcript of HTML5 CANVAS - University of Alabama
Research has shown that repetitive task-oriented movement is integral in upper-limbrehabilitation. In one study, individuals usedtheir finger to track a sine wave on acomputer screen [2]. These individualsexhibited greater tracking accuracy alongwith grasp and release function overindividuals who had not yet received thesame treatment.
Physical therapy patients may face adversity in pursuing rehabilitation:
PHYSICAL & MENTAL Distanced far from medical facilities Mobility-impairing/painful disability Forced from the comfort of home
FINANCIALCOST PER REHAB SESSION [1]: With insurance - $10-75 Without insurance - $50-350
WAVER is a web application that utilizes the3D LEAP motion device to assist patientswho have upper-limb mobility and dexteritylimitations.
WAVER presents drawing exercises to apatient that can be performed on the patient’shome computer. Drawings tracked byWAVER provide on-screen feedback to thepatient, as well as the potential to share theresults remotely with a therapist.
KEY FEATURES Small size - (2” length, 1” width) Inexpensive - (under $100) Simple usage - (USB interface)
The LEAP is a motion-capture hardwaredevice that supports hand and finger motionsas input. When a user waves their hand overthe device, the motion is translated into anarbitrary action on-screen.

1. User connects and installs LEAP device2. An exercise is selected. User can see the
motion of their hand tracked as a drawingon the screen in relation to the imagesuggested by WAVER.

REPLAY SESSION
SAVE & LOAD SESSION
WAVER allows the user to replay theircurrent session even after the canvas isreset. Users can also save sessions to theircomputer as a file containing a set ofcoordinates. Previous sessions can then beloaded back into WAVER and replayed.
WAVER provides an engaging, encouragingvisual measure of improvement forrehabilitation patients. Future versions willinclude the ability to send session resultsremotely to therapists to enable real-timeinteraction with a therapist.
