Here’s another mobile projector phone concept but this one is a bit more thought out, tho not without its problems. It offers portability and the communications functions of a mobile phone with a projector to support a new lifestyle.
As you’ve probably guessed, anything on screen can be projected onto a wall. There’s support for real time conferencing tho the camera faces the ceiling when in projector mode so I guess you’ll look like some floating head from the viewer’s perspective.
Perhaps the only reasonable utility is the ability to watch stored movies on a large screen, possibly HD since storage capacities have ramped up exponentially. Users can enjoy an array of multimedia this way, everything from videos, maybe video games, and TV.
Now to the obvious problems. Projectors produce a lot of light to get sharp saturated images. Surely a phone’s battery would run dry within minutes if tasked with such a job. Not so according to the designer. The projection system is part of a newer generation of miniaturized video components. That combined with advancements in battery technologies provide for an acceptable viewing experience.
Made of polycarbonate that is highly durable, insulating and energy saving with a graphite sheet to increase heat conductivity to dissipate heat. The edge is made of aluminum to enhance heat radiation away from the projector module and function keys. In another words, this thing would get hot!
