i need to do a interpolation on 2000 data points which i have capature using mousemove and it is stored in notepad. The problem i faced now is doing time normalization wif interpolation. For example, a user sign 3 times at different speed. First time is 4ms(fast speed), second is 6ms(standard speed) and third time is 9ms(slow speed). Using the second time as reference, i would like to make first time and third time to be the same amount of time where i have to do interpolation between the data points. How should i go about doing it?
