Abstract	Mobile phones or Personal Digital Assistants (PDAs) with advanced imaging and communication capabilities have become ubiquitous. In this work, we exploit these capabilities in the context of a Smart Home environment to monitor the activities and assist aging people. As a first step, we tackle the issue of using the PDA to track the position of a user moving within his home. Due to the importance of this problem in the realization of a Smart Home environment, numerous solutions have been proposed. In this thesis, we first discuss the technologies and the localization techniques proposed so far to achieve indoor positioning. Then, we explore the possibility of determining a user‟s location based on the camera images received from the PDA. In our system, the PDA is worn by the user as a pendant and images are periodically captured and transmitted to a Web server. The Web server returns the location of the user by comparing the received images with images stored in a database using off-the-shelf matching algorithms. The key advantage of the proposed solution lies in its ability to locate the user without the cost of additional hardware. In addition, with the purpose of assisting people with impaired vision, we evaluate the performance of an application that performs Optical Character Recognition (OCR) in photographs of medication boxes captured by smart phones or PDAs.
