LightBeam Makes Ordinary Surfaces and Objects Interactive Projector Displays and Remotes

Technische Universität DarmstadtPico projectors currently have the ability to turn any surface into a screen. However, what they can't do is turn that same surface into an interactive projector screen and average, everyday items into a remote control. Until now. Developed by a team from the Technische Univerität Darmstadt in Germany, LightBeam pairs a pico projector with a depth-sensing camera. This allows it to provide a lot of interactive features, much like Microsoft's Kinect sensor, to projected presentations.

The prototype developed by the German team actually uses a Kinect sensor to provide the motion tracking and depth perception. Any type of display surface can be manipulated within a limited 3D space with the projected image reorienting itself and rotating when the object you are projecting on is rotated. In addition to that, you can change the level of detail displayed by the projector dynamically relative to the amount of display surface available.

LightBeam also allows everyday objects to function as a remote control. That means that you can control your entire presentation by manipulating an object within the camera's field of vision. For example, you could twist anything in your hand to switch from a Flickr slideshow to your Facebook page or to go back to what you were previously viewing.

The team from Technische Univerität Darmstadt developed their prototype to examine how a user would interact with a physical object using the LightBeam system. What they discovered was that people who participated in the study were able to adapt to the idea of using physical objects as remotes for the projector very quickly and also liked the ability to quickly change between different detail levels. The participants also suggested that a good idea might be to bind digital information to physical objects like physical documents, something the team is planning on looking into in the future.

The LightBeam prototype is expected to be presented at the Conference on Human Factors in Computing Systems (CHI) 2012 in Austin, Texas in May.

BenQ Unveils Two New Laser Projectors

BenQ LX60STBenQ America, one of the most popular projector manufacturers in the country, has just unveiled an all new pair of short-throw video projectors specifically designed for use in the education industry. In addition to that, both of the new projectors use mercury-free blue core light engines for increased safety and environmental friendliness.

The new projectors have been labeled the LX60ST and the LW61ST. Both projectors were designed for a low total cost of ownership by using the blue core lighting engine, which uses a laser light source as opposed to the traditional mercury lamp. This allows both devices to achieve as much as 90% less light source power consumption, according to BenQ.

The technology also optimizes the units' brightness while offering a longer life span, according to the company. BenQ also announced that both the LX60ST and LW61ST offer an average 20,000 hours of brightness and produce an ultra-high 80,000:1 contrast ratio. An instant on/off feature also saves you a lot of time on start up and powering down while a manual brightness-level adjustment accommodates different classroom environments.

The SmartEco Advanced mode, found in both projectors, automatically determines the optimal brightness level based on your input source. At the same time, a No Source Detected mode automatically lowers brightness to 10% when no display has been detected for more than three minutes. Also, an Eco Blank mode enables blanking out the screens for both projectors when not in use to redirect students' focus, while also lowering light source power consumption to only 10%.

Finally, the BenQ blue core light engine classroom projectors offer 2,000 ANSI lumens brightness, XGA / WXGA resolution and 0.6 / 0.49 short-throw projection. Both projectors also feature two 10-watt built-in speakers, as well as a microphone input, Apple iPhone / iPad wireless display support, LAN display, USB display and 360-degree titled projection.
