Research Theme • Transducers; Converting one thing into another • User Interface, User Experience, First Person • Hooking people to gadgets • Bits Meet the Flesh • Bits Meet Eyes & Ears • Transducer Examples • Dance into Music (dance synthesizer, suction cup) • Hand into Finger Spelling (DataGlove) • Sound into Light (Singing Coach)

Discrete Events Converting continuous input into discrete events. Continuous input examples brightness, sound level, pressure Discrete output; 0/1, off/on, mouse click
Comparator- Ideal Signal Sensor + _ Digital Output Threshold Threshold SensorContinuous Input Quantized Digitized Output
Comparator- Real World SignalNoise in input causes output jitter threshold cross high for on cross low for off
Triggering Discrete Events with Hysteresis Hysteresis, “play” High threshold Low threshold Continuous Input (e.g. brightness, sound level, pressure) Quantized/Digitized Output cross high for on cross low for off

Dynamic Signature Verification“Sign and Go” (2003) • Biometric verification using handwriting cadence (timing) • A means to electronically verify customer signatures • Customer signs on a digital signature capture station • Software checks signature against reference signatures and checks for major changes in signature
Classification of Biometrics • Physical Feature • Iris, face, finger, hand, DNA • Can alter presentation • Behavior Trait • Signature, voice, gait, keystroke • Can change behavior
Identification & Verification • Identification • “Who am I?” • 1:N matching (difficult, big search) • Example: 100k customers @ 0.1% error = 100 errors • Use: Discover identity, Watch lists • Verification • “Am I who I claim to be?” • 1:1 matching (easier) • Requires identifier (not secure but unique) • token (loyalty card) • memory (phone number) • Use: Verify identity
Performance Metrics • False Accepts (FA) • likelihood that someone may be falsely accepted bad guy gets in • False Rejects (FR) • likelihood that a genuine user may be rejected good guy gets rejected • Lower the FA and FR, the better the system performance • Acceptance threshold trade-off FA to FR • Equal Error Rate when FA=FR • Failure to enroll, Failure to acquire • Light eyes (iris), thin skin (finger), simple/changing signature, noisy environment (voice) • Need backup/alternative • Example FA=2% FR=1% • 2 out of 100 good customers get rejected • 1 out of 100 bad guy attempts get in • If 1 in 1000 customers are bad guys, 1 forgery per 100,000 transactions
Biometric Comparison * Equal Error Rate estimates for relative comparison only. Actual results are highly dependent on system design, equipment, user population and experience.

Programming Robots with Playing Cards The Robosapian™ robot comes with a remote control to program robot movements. The remote control is replaced with a deck of instruction cards and bar code reader. Students choreograph movements by arranging the cards, then program the robot by scanning the cards with the bar code reader.
