Mobility Enhancement for Elderly

requirement of the award of the degree of " Master of Technology " in " Instrument Technology " is a record of bonfire work carried out by him under my supervision and guidance. Further to the best of my knowledge, this report has not been submitted for any other degree or diploma. ACKNOWLEDGEMENT I express my profound sense of gratitude to my supervisors Prof. (EPFL) for their immense interest, invaluable guidance, moral support and constant encouragement during the tenure of this work. My deepest thanks to all the professors of IDDC, for their invaluable teaching and guidance in all ways of my life. students of the MDIT Lab in IITD for their wonderful support and help they offered in realizing the goal of the project I would also like to thank all my classmates for their support in my thesis work. Finally, I am grateful to my parents, without whom none of this world is possible.

In order to give a dignified life, the mobility obtained must be at the complete discretion, will and control of the senior citizen. This can be provided only by a reasonably sophisticated and versatile wheel chair, giving enhanced ability of vision, hearing through man-machine interface, and sensor aided navigation and control. More often than not senior people have poor vision which makes it difficult for them to maker visual judgement and so calls for the use of Artificial Intelligence in visual image analysis and guided navigation systems. In this project, we deal with two important enhancement features for mobility enhancement, Audio command and Vision aided obstacle detection and navigation. We have implemented speech recognition algorithm using template of stored words for identifying the voice command given by the …
