Outline ●Problem ●Solution ●Constraints o Technical o Practical ●System Overview ●Approach ●Progress ●Timeline

Problem ●Having to manually calculate target shooting scores and decipher accuracy and precision of shots ●Process is slow and leaves room for greater human error in calculations ●Does not utilize modern day technology

Solution ●Accuracy In Your Back Pocket resolves the burden of having to occupy one’s time with miniscule and redundant calculations and analysis of shots taken ●This solution takes full advantage of readily available technology as part of the system which cuts down on extra equipment and cost

Design Constraints

Technical NameDescription Power SupplyThe system under full operation must be capable of at least two hours of battery life. Image ProcessingThe image processing software takes images from the camera and calculates accuracy within 10 centimeters of the bulls eye. MicrocontrollerThe microcontroller needs sufficient memory and processing power to save two images at a time from the camera and process computations. Wireless Communication The device must be able to transmit and receive data. Mobile ApplicationA mobile application will allow users to view animated pictures of shot data on a smartphone.

Practical TypeNameDescription ManufacturabilityComponentsThe system components are easily replaceable. EconomicCostThe expected retail price is $80- $100 based on the competitive price market.

Manufacturability ●Microcontroller peripherals must be easily replaceable ●Potential equipment failures o static electricity, humid environments, and harmful impacts

Economic ●Entire product is competitively priced ●Additional peripherals are reasonably priced ●The average user already owns part of our product
