FaceAccess — A Portable Face Recognition System Using Atmega644

We created a standalone face recognition system for access control. Users enroll in the system with the push of a button and can then log in with a different button. Face recognition uses an eigenface method. Initial testing indicates an 88% successful login rate with no false positives. There are currently commercially available systems for […]

Embedded Foot Pronation Detection Using Atmega644

Introduction and Rationale Our ECE 4760 design project integrates three different kinds of sensor measurements to track a user�s movement speed, regularity of gait, force on impact, pronation of foot, as well as other information that may be useful to a podiatrist. We believe there is a need for a cheap metering tool that can

Human Tracking Fan System Using Atmega644

For our final project we decided to construct a human tracking rotating platform that supports a fan. The platform, using dual element Pyroelectric Infrared Sensors (PIR) sensors, rotates itself independently to direct air flow to whatever position a person moves to. In addition, the fan includes another setting that allows precise rotation between two people.

Hand controller for Parrot AR Drone Quadricopter Using Atmega644

Introduction Our project is a novel hand held controller in which we use an accelerometer to wirelessly control the motion of a Parrot AR Drone Quadricopter. Rationale: The main idea of our project was building a cool glove controller for a flying platform, a quadrotor in this case, which would give the user a different

Human Tetris — Video object tracking Using Atmega644

We have created a real-time video object tracking / shape recognition device, and a fun game library to demonstrate its abilities. For our project, we wanted to push the video sampling and processing capabilities of the ATmega644 8-bit microcontroller. Using a high-speed analog-to-digital converter as an input device, we were able to sample a reasonably

Automated Pavlovian Classical Conditioning of Insects Using Atmega644

Introduction Several studies have shown that various insects possess learning and memory abilities. One approach researchers use to demonstrate such abilities is to “teach” the insect to exhibit a specific behavior in response to a stimulus. This “teaching” process is called Pavlovian conditioning. Such studies are often difficult to conduct because they require accurate timing

Accelerometer Based Hand Action Recognition using Atmega644

Introduction We created a wearable game controller that uses accelerometers to acquire action of the hand and then maps an action to an arbitrary keystroke. The types of actions we are trying to recognize should be suitable as input control for video games. We placed 3 z-axis accelerometers on tips of the thumb, the index
