Power Your Interactive Classroom With Projectors

Power Your Interactive Classroom With Projectors

A guide to one segment of education technology

According to the Society for Information Display (SID), the key feature educators consider when purchasing new projectors is image quality. Manufacturers provide resolution, brightness and contrast figures to evaluate performance, but these specifications don’t address color quality. A new metric released by SID, color light output (CLO), will allow educators to evaluate color performance between competing projector models quickly and accurately. CLO or color brightness should be the same as the white brightness or white light output to ensure that images are vibrant. When you’re ready to purchase, be sure to request the CLO specification, which will be expressed in lumens.

From mobile to interactive, and short-throw to ultra-short-throw, there is a projector to fit every district’s needs. Interactive projectors allow teachers to annotate or draw over the display, control the projector with a virtual remote, and create lessons or playback. NEC’s interactive software for iPad automatically records the projected lesson so that a timeline can be created and used at a later date. This works well for absent students and the flipped classroom, in which students watch video lectures for homework and complete assignments in class with their teacher present to help. Interactive projectors can also make the classroom more equitable for students with physical disabilities by projecting the lesson on an interactive table where they can sit and collaborate. Epson’s BrightLink 475Wi can be mounted on an iWall or iTable depending on classroom needs.

Most projectors used in the education space use 3LCD or DLP chips. 3LCD is based on LCD technology and uses an advanced, 3-chip optical engine. 3LCD boasts high CLO, energy efficiency and reliable technology. The DLP chip, made by Texas Instruments, uses a filter-free design, which may lower the total cost of ownership by not requiring filter replacements. All DLP projectors are 3D-ready and can transition seamlessly from 2D to 3D mode. Here are a few options to consider in your district.
