Smartphone evolution
Smartphones are evolving quickly. With powerful processors, high-resolution cameras, and a wide range of MEMS and sensors making new classes of applications possible, smartphones now dominate the mobile-device market.
Jungkee Lee, principal engineer at Samsung, sees more “functional modules” embedded in smartphones, including pico projectors, noninvasive glucose meters, and food spectrometers. And if we can embed a 3D depth sensor into a smartphone or tablet, said Lee, new markets such as 3D scanning, 3D measurement, 3D video, 3D gaming, and indoor navigation will emerge. “There are several kinds of architectures being explored for 3D depth sensing,” added Lee, “including Structured Light by Prime Sense (now acquired by Apple), time-of-flight by Microsoft, SoftKinetic (Fig. 2), PMD, and a mobile array camera by Pelican Imaging. Each technology has pros and cons, but the final winner should satisfy the market.” An example of one of the technologies (SoftKinetic's) is seen in Fig. 2.
