Smartphone companion projector benefits

There are three key benefits of smartphone companion projectors:

• Shared big-picture experiences. A larger image size enables a more comfortable extended viewing experience. Rather than having to gather around a small phone screen, a projected image enables more viewers to watch and be farther away from the display. While a smartphone screen is typically held at an arm’s length or closer, a smartphone companion projector (see Figure 2) can create an image size as large as 50 inches diagonally in a dim room, enabling a viewing distance of 6 feet or more from the projection surface.

• Portability. Smartphone companion projectors are typically small enough to easily fit in a pocket or a bag, as shown in Figure 3. With such a small form factor, users can bring a big picture experience anywhere they go. Battery-powered smartphone companion projectors enable cable-free viewing experiences when a power outlet is not conveniently located.

• Flexible viewing surfaces. Smartphone companion projectors can use a variety of surfaces as projection screens as long as the surface’s color, uniformity and glossiness are acceptable. While the most common viewing surface is an interior wall, as shown in Figure 4, ceilings or home exteriors can also be used.
