Stereovision, also known as S3D, has been a fascinating technology since its initial exploration and demonstration. While it may still be considered a novelty to some extent, it has proven to be a valuable and necessary capability in specific situations. For instance, in the visualization of computer-aided design and medical analysis, S3D provides a critical dimension that enhances understanding and accuracy. In commercial applications such as signage and point-of-sale systems, S3D can effectively communicate a product’s size, scale, and details, making it a useful tool for marketing and sales. In the realm of entertainment, S3D technology can elevate the experience on various platforms, including cinema, TV, PCs, and mobile devices like smartphones and tablets. However, the success of S3D in these applications heavily depends on the quality and construction of the content. When mastered correctly, S3D can create a more immersive and engaging experience, drawing the viewer into the world of the content. In static or semi-static devices like digital picture frames, S3D can be an interesting conversation piece, at least for a while. The technology’s ability to create an illusion of depth or perspective has been explored in various forms of art, including paintings from the early Middle Ages. Photogrammetry, the technique of measuring objects from photographs, has a rich history dating back to 1525. Auto-stereoscopic displays, or glasses-free displays, have been experimented in mobile devices such as handheld game consoles, tablets, and smartphones. Active shutter glasses, which switch off or block light alternately at a frame rate acceptable to the human eye’s persistence level, have also been used to enhance the S3D experience. When content is mastered correctly, stereovision can indeed provide a greater sense of realism and bring out the true 3D nature of the subject matter. As Neal Weinstock of Soliddd has discovered, the human visual system’s ability to construct 3D, known as stereopsis, can be leveraged to give sight to people with various forms of blindness. This highlights the potential of S3D technology to not only enhance entertainment and visualization but also to improve lives.
