Using a computer mouse with a computer limits creativity. When someone tries to write with a mouse, the lines come out rough and wiggly. A touch screen table gives the user a larger work surface and better control for drawing details. Touch screens allow a finger or stylus pen to draw directly into the computer. Making a touch screen table is easily accomplished. You can build a touch screen table in about an hour using a few inexpensive materials.
- Skill level:
- Moderately Easy
Things you need
- 1/8-inch Plexiglas 12 inches X 12 inches
- 11 1/2- inch X 11 1/2-inch tracing paper
- 2 cardboard boxes, 11 1/2 inches wide X 11 inches long X 16 inches high
- Open Source finger-tracking software
Lay the tracing paper on the Plexiglas, centring it. Run a line of tape along the edge of the paper on the Plexiglas to secure it. Set this aside.
Cut and remove the top fold flaps from one of the boxes. On the other box, fold the flaps down on top so it is closed. Run a line of tape across the top of the box, sealing it closed.
Stack the box without the top flaps on top of the closed box. Make sure the top box has the open side facing up. Tape around the two boxes, so they are securely bound together.
In the top box, cut a hole on one side near the bottom. It doesn't matter which side of the box you feed the webcam cord through. Feed the cord through the hole. Put the webcam into the top box. Position the webcam so that it faces upward in the centre of the bottom of the box. Tape the webcam to the bottom of the box.
Put the Plexiglas with the tracing paper on top of the box, paper side up, and tape the edges of the Plexiglas to the box. Connect the cord from the webcam to the computer.
