Illustration by Brown Bird Design Source: “Wall++: Room-Scale Interactive and Context-Aware Sensing,” by Yang Zhang et al. In theory, Zhang says, “anyone can use the technique to make a wall smart.” The entire project took four hours and cost less than $200. Finally, they wired the strips to a custom-built circuit board and covered the wall with standard latex paint. They affixed a vinyl sticker in the middle of each diamond to insulate the electrodes from one another. Removing the tape left a pattern of diamond-shaped electrodes, which the researchers connected using a grid of thin copper tape strips. To create the high-tech surface, Zhang and his colleagues applied painter's tape in a lattice pattern to a 12-by-eight-foot wall, then coated it with commercially available conductive nickel paint. “Walls are everywhere, so why not turn them into sensors for smart homes?” says Yang Zhang, a computer science doctoral student at Carnegie Mellon University, who helped to develop the concept. ![]() The technology could someday turn on lights when a person enters a room, track a player's motion in an interactive video game or monitor a child's television use. It can also detect the locations of appliances and whether they are switched on. ![]() Such a smart wall can sense human touch and track gestures from a short distance. Researchers recently converted a wall into an outsize trackpad and motion sensor by using low-cost conductive paint to create a large grid of electrodes.

Take note of the Windows OS version supported, as well as components such as processor, RAM, and storage capacity.Įlectronic whiteboards make classes and meetings more enjoyable by making ideas more engaging, and encouraging participation from everyone in attendance. If you prefer an interactive board system with an embedded PC, compare spec sheets when looking at different models. While some interactive options only support Windows, others connect to Mac and Windows computers as well as Chromebooks. It's also important to make sure you have the wall space to fit the model you order.Īnother important factor to consider is computer compatibility. The digital board you select should be big enough to command the attention of everyone in a room. Businesses use these to replace flip charts mounted on easel and display boards. There are smaller models that work in portrait orientation. Most digital boards measure 70 inches or larger. Infrared cameras on the projectors register input by tracking pen movements across the surfaces of these boards.įirst, consider size. The fifth type of digital writing boards are whiteboard projection screens that pair with interactive projectors. Most of these can accept pen and touch input, and they allow multiple users to write on them at the same time. For full-featured touchscreen whiteboards, consider pen-based units with electromagnetic surfaces. These have mesh or membrane surfaces that depress slightly when registering touch. ![]() The third category consists of resistive touch-based models. Another type of infrared smart board accepts pen and touch input as well as dry-erase markers. This system works on any flat surface including regular whiteboards, walls, and chalkboards. The most affordable type is the pen-based infrared whiteboard. Each type uses a different technology to project content on screens. There are five broad categories of interactive digital boards. While these smaller alternatives are for personal use and small groups, interactive models are big enough to be visible across school classrooms and business conference rooms. Digital boards are functionally similar to tablet PCs and electronic paper displays but have much bigger footprints. Although it looks like a regular whiteboard, this device usually has a touch-enabled surface that accepts pen and/or touch input. Compared to regular marker boards, interactive displays make content come alive by allowing users to write and digitize notes, as well as share and save them.Īlso known as a smart whiteboard, an interactive board is a large display that houses a computer or serves as a peripheral for a computing device. While they're popular teaching aids in classrooms, you can also find these giant displays in corporate conference rooms, sports training rooms, and broadcasting studios. Digital whiteboards encourage interaction and collaboration among users in learning environments.
