How do you balance weight vs. cost vs. brightness?

3M: You don’t. Each criteria must be weighted equally for market success.

Hitachi: If you’re a traveling businessperson, weight will be a more important factor. At the moment, brightness doesn’t seem like a huge issue, because you can get sufficient brightness from almost any compact business projector.

InFocus: Most customers use mobile projectors in small groups (three to eight people) on screen sizes between 60in. and 80in., so 2000 lumens-2500 lumens is perfect for this application.

Mitsubishi: Weight is for the convenience of the presenter, but brightness is for the overall effectiveness of the presentation. Cost is usually affected by weight more than by brightness because technology has improved in such a way that lamps are more efficient, whereas smaller components tend to command a price premium. However, if their presentation sites are varied, they won’t know how bright, how many windows, or if there are no curtains in the presentation room. Then the presenter will need a brighter projector.

What criteria give a portable projector the necessary road-worthiness and survivability?

3M: Robust design using a single imager approach is essential for road warriors. LED illumination will enhance the safety and reliability of such projectors.

Hitachi: Weight, having a usable carrying case, simple connections, and wireless connectivity.

InFocus: Most people use their mobile projectors with notebook PCs, so customers need to look for three big categories of features: Is it easy to connect to my notebook computer? Does the image quality match the colors on my PC? Does the resolution match my latest computer?

Mitsubishi: Portability—size and weight and durability of the projector. A small projector is roadworthy—it’s easy to store and carry, and easy to protect. Durability—our small business projectors use DLP technology with a closed light engine that is relatively impervious to dust, so it can handle various presentation environments.

NEC: Those that use mobile projectors typically need to setup and tear down their projector and move on to the next meeting quickly. Because of this, a true mobile projector should be able to display an image seconds after it has been turned on, as well as cool down very quickly without damaging the lamp, therefore shortening the life of the lamp.

Sony: Shell material (metal vs. plastic) and features like recessed lens and input connectors. These help the compact business projector from getting damaged when it is being carried.
