In this research we propose a new motion classification method using principal component analysis to improve operability of a 3D gesture interface that assists text input on mobile devices. By applying principal component analysis to time-series finger scale data, the amount of information is reduced and only necessary information for classification is obtained. The result of experiment using a numerical keypad application showed that up to third principal components had eigenvalues more than one, and that the cumulative contribution ratio was more than 99%. The result of discriminant analysis showed that the proposed method achieved 94.3% recognition accuracy for mobile phone number input and 94.8% for circular constant input. |
