Homemade Electronic Whiteboard

CSEF · 2011 Mathematics & Software

Parker A. Williams · Los Cerritos Middle School, Thousand Oaks, Ventura County

Overview

Objectives/Goals My goal was to determine if larger monitors would provide higher accuracy when used with an electronic whiteboard program. Methods/Materials Using an infared camera connected to my computer wirelessly via BlueTooth, I used a homemade infrared light pen as a mouse pointer. This was tracked by the infrared camera and data was collected by a software program. I tried several different monitors of various sizes to see which one was most accurate. Results A larger computer monitor provided better accuracy. Conclusions/Discussion My conclusion supported my hypothesis. Electronic whiteboards benefit from larger monitors.

Summary statement

Accuracy of an electronic whiteboard made from a homemade infrared light pen, a Nintendo Wii remote, and a BlueTooth dongle on a PC.

Help received

Dad purchased BlueTooth dongle and infrared LEDs and supervised soldering of infrared light pen.
