Engineering Your CommunityRoom Control
Ashley Lengel, Evan Franz, Ethan Fitz
Original Ideas and Goals
• We all noticed that residents have a need for more tools in their rooms
• Things that came to mind:– What do they do if they fall from their chair or bed?
• More control in their rooms would give the residents an increased sense of independence, thus meeting Beechwood’s mission.
Project: Help Button• If a resident falls from their
chair or bed and can’t call for help, what do they do?
• We’d like to have a sensor in the room (perhaps along the floor/door/ceiling) that the resident can activate with their vision.– Need to consider the
position of the resident after the fall and their inability to maneuver themselves to get to the button.
Technology
• Raspberry Pi B+– Capable of handling
the vision processing coding necessary to make the device work
– Will utilize MATLAB and Simulink to program
– USB ports, Ethernet port, camera connector, MicroSD
Technology Cont.
• Camera– Specific Raspberry Pi
compatible camera– Infrared LEDs
increase sensitivity enough to hopefully pick up light reflection
– Slim design makes for easy casing
How Will It Work?• Will connect with
the help button system already in place– Triggered by
vision sensor rather than push button
Current Status
• Have educated ourselves with the programming (MATLAB and Simulink)
• Have combined camera and Pi board• Designed a casing for end product• Have room schematics to figure out location of
unit
MATLAB and Simulink Programming
• Have successfully established communication between camera and board
• Made a flow chart to get the camera to do color recognition and filtering– Finding more research on specifying that
further to shape/face recognition
The Unit
Looking Forward
• We’d like to hopefully pass this project on to a group in the next offering of this class
• We’ll continue to research and put work into this
We’d like to thank Beechwood Home for allowing us to work with them!
