For our ECE 4760 final project, we designed and built a wireless computer pointing device with accelerometer based movement control. Our implementation allows the user to wear a set of hardware (a glove and connected armband) and control a cursor through different hand orientations and finger presses. Users can operate their computers with their hands […]

An Introduction “A glove embedded with accelerometers to play a hand motion-controlled chess game” project soundbyte For our ECE 4760 final project, our team designed and built a system with the ability to play the game of chess using embedded gloves. Each player wears a glove (there are two gloves for two players) and uses

Introduction “An encrypted laser-based friend-foe identification system to prevent friendly fire in battle” This project implements an Identification Friend-or-Foe (IFF) system for use by soldiers to prevent friendly-fire. The inspiration for the project is derived from Identification Friend-or-Foe (IFF) transponder systems currently used on fighter aircraft and military vehicles. Fighter aircraft fitted with an IFF

Introduction In this project, ultrasound around 24kHz was used to detect movement near an object. Waving a hand or other solid object near the source of the ultrasound (speaker) causes a shift in the frequency of the sound, which is then detected by a microphone. We detected characteristic shifts in frequency to determine whether motion

Our project is inspired by the commercial product, PicoDopp, which uses a similar scheme for foxhunting. Foxhunting is a contest where participants try to locate a transmitter, called the fox, simply by monitoring the signals it transmits. Typically this is done using highly directional antennas — antennas that only receive signals from one direction. However,

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
