TRANSCRIPT
Haptics Final Project:Using a Sensor Glove to
Write in the AirPaul Taele
Spring 2008
Goals
• Write stuff in the air without a pen.
Initial Gestures
Original Posture Classifier Setup
• Tools:– P5– CyberGlove
• Posture Classifiers:– k-Nearest Neighbor– Naïve Bayes– Neural Network
Postures - Results
• P5– NB: 10%– kNN: 50%– NN: 70%
• CyberGlove– NN: 75% (all 23 sensors)– NN: 100% (3 index finger sensors)
Postures - Analysis
• Desired 100% for posture classification.• Used CyberGlove device and Neural
Network classifier for postures.• Used two easily separable gestures
instead of four.
Hand Gesture Segmentation
• Simple for two very separable gestures.• Classify each time state in an instance
using the trained NN.
Final Project Setup
• Tools: CyberGlove• Language: Java• Posture Classifier: Neural Network• Sketch Classifier: $1• # of Postures: 2• # of Gestures: 4
Final Postures
Final Gestures
Training Data ($1)
• Created templates from 3 users.• Each user gave 5 examples for each
sketch gesture.

Test Data ($1)
• Data was tested on consecutively-inputted sketch gesture.
• Postures first extracted from gesturing stream.
• Time points of those postures used to classify sketch gestures.
