1. SE 367: INTRODUCTION TO COGNITIVE SCIENCE SUBMITTED BY:- HEMANGINI PARMAR Y8214 Cross- Modal Object Recognition is Viewpoint Independent Final Project Presentation

2. Objects Dimensions~ (3-5)cm x 2cm x 2cm Lego bricks used Mirror images avoided Very similar objects to prevent distinctive cues

3. Objects

7. Experimental Setup 20 female participants: age group=19-21 years Random sequence for [modality,rotation] per object to avoid any pattern formation where modality={VV,VH,HV,HH} rotation={UR,X,Y,Z} Visual mode= 15 sec Haptic mode=30sec

8. Haptic Setup

9. Visual Setup

10. Observation Accuracy

11. OSIQ

12. Correlation with Spatial scores

13. Correlation with Object Imagery Scores

14. Conclusion The hypothesis that cross-modal recognition is viewpoint independent is validated The hypothesis that a higher level representation is involved in cross-modal object recognition is still unclear.
