1. A computing device, comprising:
a processing device;
a touch input device in electronic communication with the processing device; and
a memory device in electronic communication with the processing device and having electronic instructions encoded thereon;
wherein the electronic instructions, when executed by the processing device, cause the processing device to:
receive a first sensed path corresponding to a first user input on the touch input device, the first sensed path including a first wave pattern;
receive a second sensed path corresponding to a second user input on the touch input device, the second sensed path including a second wave pattern;
determine a difference between the first wave pattern and the second wave pattern; and
adjust an input interpretation algorithm based on the difference between the first wave pattern and the second wave pattern.
