Outline Background Problem Solution Constraints o Technical o Practical Approach Progress o Timeline Questions

Background 50% to 70% of Americans do not take their medicine as prescribed [1] The target market group for the MCA are people 65 years and older [2]

Current Market $39.99 Monthly Subscription Cellular Notifications Remote Monitoring Progress Reports $39.99 Monthly Subscription Cellular Notifications Remote Monitoring Progress Reports $15.00 Monthly Subscription Cellular Notifications Push to Refill Button Progress Reports $15.00 Monthly Subscription Cellular Notifications Push to Refill Button Progress Reports [4] [5] Med Minder GlowCaps [2] [3]

Problem Current medication reminder devices do not have a clear way to monitor that medication is being removed from the storage containers. Current devices lack a way for the caregiver to observe medication in dosage compartments remotely.

Solution The MCA is a user-friendly device that monitors noncompliance more accurately than other existing products. The MCA: - Stores daily medication - Alerts patients during dosage times - Caregivers can visually observe medication compliance

Technical Constraints NameDescription Power SupplyThe device must use 120V AC. USB The device must use USB interface with computer. Quantity of Pill Containers The device must have 28 containers. Empty Container Detection The device has to detect when a pill container is empty. Remote Container Visibility The device must be able to visually see the pill container.

System Overview Webcam Power Supply Patient NotificationMicrocontroller Computer Software Remote Caregiver Access

Practical Constraints Ethical The device must not be used to spy on the patient.

Practical Constraints Sustainability  Device must be able to handle moderate use  To prevent complaints, the device must be easy to use and not cause stress to patients.

Approach Pill Detection PROSCONSCHOICE?? [6] -detects if a mass is being removed from the device - Small weights of pills require highly sensitive weight sensors -simple to implement -cheap -doesn’t improve on existing designs -less certainty of pill compliance -takes advantage of webcam which is already part of system -requires a powerful processor for image processing -requires more coding Load Sensor Image processing Open/Close Contacts

Approach Image Processing COSTSPEEDRESOURCESCHOICE?? > $1500MODERATEMEDIUM FREEFAST LARGE MatLab [7] Open CV

Approach Remote Access PROSCONSCHOICE?? - available to anyone with internet -requires a monthly fee ($4) to host -requires more coding to interface with device Remote Desktop Login to Software - Easy to implement -FREE -requires a dedicated windows pc for device Website Calendar [8]

Approach Patient Notification PROSCONSCHOICE?? Easy to see Original Requires moving parts Simple Inexpensive None Clear indication of which compartment to use Requires mechanized containers Rotating Light LEDs for each container Automated Opening Container
