What this helps track
Shape tracing assessments use guided on-screen tracing tasks to help track fine motor control, hand steadiness, and visual-motor coordination over time.
Shape tracing
Shape tracing assessments on iPhone and iPad
Guided tracing tasks for hand control, coordination, and visual-motor precision.
Why it matters
Tracing performance can reflect changes in coordination, steadiness, and visual-motor integration. Repeating the same guided shapes over time makes subtle changes easier to recognize than self-reporting alone.
What this assessment measures
Shape tracing samples visual-motor integration: how accurately your hand can follow what your eye is guiding it to do. That combination is sensitive to changes in coordination, fine motor control, and in some conditions subtle cerebellar signal. The task complements pure tremor and tapping tasks by focusing on control across a continuous path rather than a single action.
How it works
What a typical session looks like
Each session is short and guided end-to-end, so you can focus on the task.
- 1Rest your hand and device on a stable surface.
- 2Follow the on-screen path with your fingertip or stylus as guided.
- 3Complete a mix of curved, geometric, and spiral shapes.
- 4Session takes about two to three minutes.
- 5Use the same hand and device orientation each time for comparable results.
What your results show
You'll see a path-deviation score per shape, plus a session summary against your recent range. Reviewers look for trends in precision and smoothness across weeks rather than reacting to a single tracing.

Common questions
Frequently asked questions
Quick answers about the shape tracing assessment on Alumina Health.
Is a stylus required?
No. A fingertip works well. If you already use a stylus regularly, using the same one each time will keep sessions comparable.
What does path deviation actually measure?
It measures how far your traced path strays from the target shape. Rather than a diagnostic threshold, the score is best read against your own baseline over multiple sessions.
Can I switch hands between sessions?
For clean trend data, keep the same hand and setup each time. If both hands are relevant, run separate sequences for each.
How is this different from tremor tasks?
Tremor tasks focus on steadiness during holds and short drawings. Tracing focuses on visual-motor precision across a continuous path, which can capture coordination changes tremor tasks might miss.
Who it may help
Helpful for monitoring related concerns
- People living with multiple sclerosis (MS)
- People monitoring tremor or coordination changes
- Caregivers tracking fine motor consistency
Alumina Health is designed to support structured tracking, not diagnosis. Always consult a qualified healthcare professional for medical advice.
