Our ECE 4760 final project was to create a virtual saxophone that uses Direct Digitial Synthesis (DDS) to synthesize the output notes. Pushbuttons are connected to a PVC pipe to mimic the saxophone’s mechanical structure, and a microphone that detects noise is used to determine whether or not the user is blowing into the device. […]

Our project implements a touchpad input system which takes user input and converts it to a printed character. Currently, the device only recognizes the 26 letters of the alphabet, but our training system could be easily generalized to include any figure of completely arbitrary shape, including alphanumerics, punctuation, and other symbols. A stylus is used

Introduction “A portable Glove Based Sign Language Translator with LCD Display, Speech Synthesis, and Sign Language Education Software” Sign language is a language through which communication is possible without the means of acoustic sounds. Instead, sign language relies on sign patterns, i.e., body language, orientation and movements of the arm to facilitate understanding between people.

Documentation HelioWatcher: Automatic Solar Panel Control Jason Wright (jpw97) and Jeremy Blum (jeb373) Introduction We designed and built a system to automatically orient a solar panel for maximum efficiency, record data, and safely charge batteries. Using a GPS module and magnetometer, the HelioWatcher allows the user to place the system anywhere in the world without

Introduction In this project, we built a digital multi-meter utilizing near-field communication concept. The system established a bidirectional wireless communication between the measurement unit and the base unit. The measurement unit is in charge of measurement and transmitting the result to the base, while the base is the user interface for measurement mode selection and

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

Introduction Our project is a self-contained system that helps people develop the musical skills of perfect pitch and relative pitch. Push buttons allow the user to navigate a graphical user interface (GUI) on a liquid crystal display (LCD). In perfect pitch training mode, a note is played and the user tries to identify the note

SensCap is a device that guides the visually impaired around obstacles. Introduction We designed and built a device to be worn on the head and around the hip to aid the visually impaired maneuver around obstacles. It provides information about obstacles near and around the head. When used with a cane, the user will have

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

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.
