PenPlay II: A Painting Toy for Users of All Ages (ISR IP)

ISR intellectual property available to license

Inventors
Andrew Sears, Ben Shneiderman

Description
To help overcome the stress of long hours working at a computer, developers at the University of Maryland Human-Computer Interaction Lab have designed a fun, creative, and relaxing diversion.

PenPlay II™ is an entertaining, artistic, sound-generating software package which allows the users to draw directly onto the computer monitor. Requiring only an IBM PS/2, AT, or compatible computer, MicroTouch touchscreen monitor or Microsoft-compatible mouse, VGA graphics, and a minimum of 512K of memory, users can create an endless array of designs.

PenPlay II™ offers users ten different designs: Lines, Dots, Stars, Shells, Ripples, Needles, Circles, Triangles, Rings, and Calligraphy. Some of the designs always stay the same size; others increase in size or are spaced further apart when a quicker touch is used. The Line feature allows users to draw a thin line in any direction, while the Calligraphy feature works much like a fountain pen, with varying thicknesses. The following is a brief description of a few others:

Needles
Looking much like pine needles, this design "sprouts" in the direction of the motion, increasing in length with speed.

Ripples
Eight rings, one inside the other like a bullseye, which was designed to imitate a ripple in a puddle of water. Each ring appears in a different color. When drawn in a series, Ripples resembles a Slinky.

Stars
Each star has eight points. The quicker the motion, the larger the star.

With the use of a touchscreen monitor, the finger guides the direction and flow of patterns. If a touchscreen monitor is unavailable, a Microsoft-compatible mouse will serve the same purpose. At any time, the screen can be cleared to either a black or white background.

PenPlay II™ users can draw with a single color picked from the color palette, or have the colors constantly rotate in a rainbow display. As an option, users can generate sounds with each stroke.

For those who like to save their creations, there is a feature which allows the recording of a design for future play-back.
