What therapists use it for
OT · Fingers
Pre-writing strokes: a steady line from point to point
Trace the sky joins stars into a picture with one fingertip on a tablet, the line kept on the path between them.
RecordedStaying on the lineSmoothnessAimOT · Eyes
Visual-motor integration: seeing the next target and reaching it
In Trace the sky the next star shows where the picture goes; the child finds it and touches it, and every touch is timed and placed.
RecordedReaction timeAimAccuracyABA · Mind
Starting on cue and staying with the task
Trace the sky waits for the first move after each instruction, and notes how long the hand stays on the activity and whether a miss is tried again.
