History

In 1991, SMART Technologies introduced an Interactive Whiteboard, on which the image from a projector was displayed. A USB connection allowed the presenter to virtually interact with the projection. Other after-market products aimed at working with existing projectors (Mimio and eBeam) came out after that.

Interphase Corporation (NASDAQ:INPH) was founded in 1974, and filed for initial public offering in 1984. In 2010, penveu was invented. The company developed the concepts and tested them for two years until unveiling the product at the DEMO conference in Santa Clara, California, on April 18, 2012. On May 30, 2014, the product was released to the market.

Since the product is made of two electronic boards (one in the handheld pen and one in the base station), the engineering department named those two boards the PEN and the VEU (video enhancement unit). PENVEU became the name of the device.

On September 30, 2015, Interphase Corporation announced it had ceased operations and commenced bankruptcy proceedings.[1]

Technology

The core of the penveu technology surrounds a camera located near the tip of the pen, but is implemented in two parts of the penveu system: the PEN, and the VEU. The video signal (VGA) that comes from the computer towards the display device (projector or TV monitor) is intercepted by the VEU box. Over there, visual targets are inserted into that video stream. Those targets include position-encoded information, related to the location of each target within the display area. The targets are inserted as increased brightness in one frame, and reduced brightness in the next frame. There is a digital signal processor (DSP) in the pen, which calculates the position of the tip based on the information retrieved from the targets detected.

As a result of the positioning targeting system being integrated with the displayed image, penveu never requires calibration. Since the only installation required is the connection of the video (VGA) cable from the projector and computer into the penveu system, as well as USB and power.

Awards

Penveu received several awards since its introduction into the market, including the "Best of InfoComm 2012",[2] the 2014 "Innovations in Design and Engineering" award[3][4][5] and the International Society for Technology in Education (ISTE) inaugural Best of Show" award.[6][7]
