Introduction “An ultrasonic range-finding hat with variable haptic feedback for obstacle detection.” -Project Sound Bite For our ECE 4760 final project, we designed and implemented an ultrasonic range-finding hat that uses haptic feedback to alert its wearer about obstacles in his or her path. The hat is equipped with an ultrasonic transmitter/receiver circuit, which is […]

Introduction: Our final project for the ECE 4760 course consists of a wearable device to provide aid for the visually impaired. An ultrasonic distance sensor located on a hat collects data of the surrounding environment scanning the area ahead of the user, and uses this data to give an audio feedback through stereo headphones. Using

Our acoustic wayfinding device utilizes ultrasonic range finders and haptic feedback to facilitate indoor navigation for the visually impaired. The technique of acoustic wayfinding uses auditory cues, such as sounds from the natural environment or sounds created artificially, to determine an individual’s surrounding physical space for the purpose of navigation. Our device is an automated

Introduction “A device that tracks sound impluses with a three microphone array” We designed and build a 2-dimentional Acoustic Impulse Marker system which is capable of detecting a sharp sound anywhere in its vicinity and precisely marking its source vector with a servo based pointer. Our system has a full 360 degree range, and is

Introduction We have created an autonomous, servo-controlled fire extinguisher that is capable of aiming photo sensors and a water nozzle along two axes to detect and extinguish candle fires a short distance (about 1 ft.) away using a small burst of water. Our inspiration originally came from thinking about an automated toy sentry turret that

Our final project moves and clicks a mouse cursor on a computer screen by tracking where the user’s eye-movements using infrared eye-tracking technology and a gyroscope. The motivation for this project came from thinking about applications of infrared technology. We narrowed our ideas down to eye-tracking because of its potential benefit to the disabled and

Introduction For this project, we created a noninvasive heart rate and blood pressure measurement tool with the intention of gathering data for large-scale analysis for the automatic prediction of heart disease. In modern society, patients often have access to a wealth of electronic data concerning their social networks and surroundings, but have little personalized insight

Introduction For our ECE 4760 final project, we designed and implemented a remote controlled persistence-of-vision (POV) display that is able to display multiple patterns based on remote input. The primary components of the display are a rotor and a motor. The rotor is mainly consisted of a row of LEDs and a microcontroller. The microcontroller
