Summary:
Rubine's feautres are often considered the pioneering work in gesture recognition. This paper explains the intuition behind these gestures, and the implementation of a toolkit called GRANDMA. The paper details the MVC architecture used in the toolkit, the statistic features of a gesture, how a classifier is training and also eager and multi-finger gestures.
Discussion:
The main takeaway from this paper are the eleven features (which will be discussed in the next reading) , and the approach to train a linear classifier using these features.
The main aim is to find the class that maximizes the value of v according to the following relation:
The computation of the weights for each feature of each class is done with the following relations:
The paper also proceeds to define a probabilistic heuristic for rejection and also describes the Mahalonobis distance which measures how many standard deviations away a gesture is from a given class.
