MicroVision originally designed and produced pico-projectors based on MEMs (micro mechanical systems) and lasers. These are distinguished from conventional projectors by producing images which are always in focus (no adjustment from the user required). As such, the product focus was on mobile consumer devices, though MicroVision's technology also aspired to 3D scanning applications, which eventually focused automotive LiDAR.
I became interested in the technology when Sony's involvement validated the technology, and profited handsomely during that management's tenure, which involved a reasonable approach to growth. However, early warnings had me playing hands off a few years later, and experience made me want nothing to do with later management. My private service still offers analysis on much better plays in the same spaces that MicroVision targets.
