Some gestures have sensor values that are very similar or overlap. For some gestures, misidentification can have significant consequences. For example, a Pinch Grasp (PG) might be used for many daily tasks such as picking up and manipulating objects, but Pointing with the Index finger (PI) might only be used to press buttons, a task that other gestures could be substituted for if needed. This makes it far more important to recognize PG than PI. In fact, accidentally mistaking PI for PG could lead to dropping objects the user is trying to interact with. Assume of the 5 2d gesture arrays in gestureList two of them (PI and PG) have overlapping values such that PGmin> PImin and PGmax

Wearable sensors are devices that can be worn on various parts of the body to collect physiological
data. This data can be used in wide variety of applications such as health monitoring (e.g. monitoring a
person’s heart rate) to gesture recognition (e.g. identifying a pointing motion). These wearable sensors
gather information from the user and provide output that is sorted into different categories. In the case
of gesture recognition, the categories are the gestures that a person can perform. It is important for the
wearable sensors to correctly identify these gestures so the wearer can perform their desired action (ex.
maintaining a pinch on an item instead of dropping it). A model can be built using a number of worn
sensors that describes gestures made by the user, but the model must be trained.

objects the user is trying to interact with.
Assume of the 5 2d gesture arrays in gestureList two of them (PI and PG) have overlapping values such
that PGmin> PImin and PGmax<PImax. How would you perform the following?
- Ensure that there is no possibility of PG being mistaken for PI
- Use the minimum number of testing loops to do so
