The Optoelectronics group of Vishay Intertechnology, Inc. today introduced two new fully integrated Automotive Grade proximity sensors with high resolution up to 20 µm for force sensing applications. They each combine a photodiode, amplifier, and ADC circuitry in a 4 mm by 2.36 mm surface-mount package with a low 0.75 mm profile. The VCNL3030X01 features an on-board […]
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 The purpose of the project is to present a new approach on the design of security systems by using a touch sensitive device. Security is a permanent concern in a variety of environments ranging from physical access restriction in home and industrial settings to information security in digital systems. Numeric passwords, fingerprint recognition, and

Content Page 1. Introduction 1.1 Sound-Bite Our final project recreates Rush Hour as a video game that is played using a touchpad implemented using 2D electric-field (E-field) sensors. 1.2 Motivation Rush Hour appealed to us as one of the better puzzles out there. Its level of difficulty can range from simple games to hard ones, thus making

Introduction Many digital artists draw with mice on computer or use tablets. However, tablets are often very expensive. Using the mouse is not always as accurate and one needs a steady hand. Our project attempts to create a lower budget alternative to the tablet that is easier to draw with. We use a stack of

Introduction Our electronic drawing board integrates an easy human interface with a standard electronic display; specifically the a touchpad and an oscilloscope or TV screen. The rationale behind the drawing board is to be able to create a free hand sketch using the touchpad and have a real time display on a screen which can

Or, an exercise in input and output multiplexing, and working with bits. And a submission for the Arduino contest. This is an implementation of a tic tac toe game using a 3×3 array of bicoloured LEDs for a display, a simple resistive touchpad, and an Arduino to tie everything together. To see how it works,
