  2. Introduction • It is our goal to develop a new sensory system that will allow a system operator to determine the availability of an area of interest. Sensor results are conveyed to a remotely located system display. • This new system is based on a collection of existing technology that will be used to collect real time data within a perimeter of operation. • Three situations concerning area of interest availability have been identified. • An individual is located in an AOI. • Objects or possessions have been left in an AOI. • The AOI is unoccupied.

  3. Motivation • Our motivation for this product is to increase consumer efficiency by developing a product that improves time management through the use of a more advanced organizational system. • Currently methods for determining and monitoring the availability of an area of interest require large amounts of wasted time and effort.

  4. Possible Applications • Library Tables & Study Areas • Classrooms & Conference Rooms • Energy Conservation • Heating and air systems configured to adapt to information collected by the occupancy system. • Sociology • What areas do individuals tend to occupy?

  5. Current Competition • People Counters • Technology that uses motion detectors to count the number of people in an area of interest to determine occupancy levels • Surveillance & Security Companies • Energy Efficiency Companies • Systems that perform tasks such as turning off lights or appliances when they are not in use

  6. Customer Needs • Display • The ability to view information from a remote location • Privacy • The system does not invade consumer privacy, i.e. no cameras • Appearance • Does not interfere with normal activity • Reliability • The system requires minimal user intervention

  7. Customer Needs - 2 • Versatility • System is extensible and expandable • Can be implemented in a variety of locations • Accuracy • Can adjust for different occupancy scenarios • Cost • The system is priced affordably

  8. Key Sub Problems • Sense Presence in Area of Interest • What sensor(s) can give us the best information regarding occupancy while still maintaining power and privacy restrictions? • Process Sensor Data • What is the best method to accurately process sensor data and efficiently relay necessary occupant information?

  9. Interesting Sub-Solutions • Sense Presence • Motion Sensor • Accuracy concern • Thermal Sensor • Unable to adjust to different occupancy scenarios • Camera • Privacy Invasion • Combination Sonar & Thermal (selected) • Satisfies level of accuracy, desired information, and most customer needs

  10. Interesting Sub-Solutions - 2 • Process Sensor Data • FPGA • Not in our skill set • PC • Not Versatile • Sensor Node (selected) • Versatility & Ease of use

  11. Final Concept • A combination sensor scheme • Thermal & Sonar • Possibly aggregated in one box or a multi-part design • Sensor Node • A microcontroller with radio • Used to analyze sensor data and transmit relative information

  12. Diagram - Aggregate Model

  13. Diagram - Multi-part Model

  14. Proto-type • Detect people, object, both, or neither in a given area represented by a table • Break occupancy area (table) into a quadrant to show region occupancy • Transmit the data wirelessly to a gateway mote connected to a PC and display information on PC
