  1. Idea: Cell phone based motion detector How: Most cell phones do have camera which can be used to capture image. If we compare two pictures taken with the camera from the same position at certain time interval, the difference in these two is an indication of some physical activity. Why: Cell phones are idle in the night. While charging the phone, if it is placed at an appropriate location, with such a software module, it can be concurrently used for security purpose. It requires no additional hardware.

  2. Research: Selection of appropriate time interval is required, so that a jumping cat or flying bird doesn’t trigger the alarm, but suspicious slow movements are detected. Similarly, appropriate degree of difference between the two frames is to be evaluated so that small moving objects like mosquitoes and flies do not trigger the alarm. Supplementary: The pictures could also be uploaded to a computer or internet wirelessly through Bluetooth, wi-fi or GPRS. In that case, the setup doubles as a recorder as well. Marketing: To be distributed free of cost, with credits for the concept and programming. Inclusion of University information and country of origin may be helpful in building a profile for both.
