The problem Wise Hand solves

Stereotypic Repetitive Hand Flapping Movement Detector Children with Autism[MedTech]

Challenges we ran into

For instance, when a child is trying to
drink juice, the subject exhibits to and fro motion of the hand.
In that case, the accelerometer and the gyroscope read the
values as the motion, but they should not be considered as a
stereotypic motion. Considering the issue, the concept of time
span is included while writing the algorithm.
In the manual technique (time domain), acceleration is
basically being observed, and the sum of acceleration of three
directions during flapping motion is set as a threshold value.
The time period between two hand flapping motions is also set
after observation, along with the flap count threshold. Whenever
this threshold is met in the system, outputs get triggered (motor,
an alert message to the parent, and sensors data logged in the cloud).
