OUTLINEProject overviewBlock diagramDesign challengesIndividual contributionsProject demonstrationQuestions / discussion

PROJECT OVERVIEW ATM with enhanced security ATM is idle when vacant Detects presence of user Authentication process

RFID card 4-digit PIN Facial recognition

Update cash balance in cash card

BLOCK DIAGRAM

DESIGN CHALLENGES RFID-related

Strength of signal emitted Write issues (Absence of feedback) Read issues (Unstable data rate)

Face recognition-related False negatives Disparity using two webcams

DESIGN CHALLENGES Packaging

Steel frame interfere RFID Height of the occupancy sensor

and camera Degree of the screen monitor to

be at comfortable level of the user

DESIGN CHALLENGES GUI

Sensitivity for gesture recognition Parallel programming for sampling peripherals

while running the UI pages Test all the corner and fail cases and send correct

ACK signal to the microcontroller

INDIVIDUAL CONTRIBUTIONS Team Leader – Yu Chen Lim Team Member 2 – Xue Yuan Wong Team Member 3 – Chuan Yean Tan Team Member 4 – Tung Lun Loo

TEAM LEADER – YU CHEN LIM Parts research and order Circuit design and prototyping Microcontroller code

RFID read Serial communication

PCB Design Face recognition code Packaging

MEMBER 2 – XUE YUAN WONG Drew schematics Prototyped preliminary circuit Wrote microcontroller code

RFID write Keypad & occupancy sensor

Soldered PCB components Designed how Intel Atom and microcontroller

communicate Integrated keypad and RFID code into GUI

MEMBER 3 – CHUAN YEAN TAN Design myATM’s packaging Set up database and server Develop scripts

COM port interface Copy large data(photo) over local network

Develop GUI Integrating database and signals from COM

port to GUI Develop gesture recognition

MEMBER 4 – TUNG LUN LOO Brainstorm project ideas, research parts and order Setup OS and dependencies of the libraries for QT,

OpenBR, and OpenCV in Atom Board Setup Face Recognition and Distance Based Algorithm

API Integrate every individual part of the codes into GUI,

debugged individual peripherals and design the flow of the GUI- RFID read and write, occupancy sensor, server integration, data passing, face algorithm, keypad

Design the dimensions of myATM and assemble the woods together.

PROJECT DEMONSTRATION1. An ability to use face recognition to verify the

identity of the user2. An ability to use touchpad to recognize gestures

for menu navigation3. An ability to sense the presence of a user in

front of ATM4. An ability to read and update the value in a cash

card5. An ability to use keypad to input numbers for

PIN validation and transaction purposeshttps://engineering.purdue.edu/477grp5/video/FinalSeniorDesignMovie.mp4
