From Glasstron to VR: The Sony Headgear Saga (1992-2013)

Because Wearing a TV on Your Face is Totally Normal

Sony’s journey into head-mounted display (HMD) technology has significantly shaped immersive personal viewing experiences. From the 1990s Visortron to the Glasstron series, Sony's innovations paved the way for modern VR and AR systems. Let’s explore the notable Glasstron models and their impact on immersive technology.

1992: Sony Visortron - The Beginning

Sony’s Visortron, introduced in 1992, marked its entry into HMDs. It used a non-stereo LCD screen to simulate viewing a 33-inch TV from four feet away. Weighing 200 grams, it was lightweight and was even used by Japan Airlines for in-flight entertainment. However, its lack of stereo vision limited its depth and realism.

1996: Sony Glasstron PLM-50 - Enhanced Immersion

The 1996 Glasstron PLM-50 introduced dual LCD screens for improved clarity and depth. It also included built-in earphones for a complete audiovisual experience. Despite these advancements, its resolution and field of view were still limited by the technology of the time.

1997: Sony Glasstron PLM-A35 - Simplified Design

The Glasstron PLM-A35, released in 1997, simplified the design with opaque lenses and dual LCD screens. It supported SVGA input and was reliable for users seeking straightforward HMD functionality. However, it lacked advanced features of higher-end models.

1997: Sony Glasstron PLM-A55 - Versatility

Also from 1997, the Glasstron PLM-A55 featured a mechanical shutter to switch between opaque and see-through modes. This added versatility, allowing users to blend digital content with their surroundings. It did not support SVGA input but was valued for its flexibility.

1998: Sony Glasstron PLM-100 - Significant Advancement

The 1998 Glasstron PLM-100 brought color LCD displays, richer visuals, and SVGA input. It included the mechanical shutter for mode switching but faced occasional stability issues. This model represented a significant leap in personal viewing technology.

1998: Sony Glasstron PLM-S700 - Peak Innovation

The Glasstron PLM-S700 and PLM-S700E, launched in late 1998, offered over 1.55 million pixels and SVGA resolution. They featured see-through modes via LCD shutters. The S700 supported NTSC, while the S700E was for PAL input, showcasing the pinnacle of Sony’s HMD innovation.

2012: Sony HMZ-T1 - Entering 3D

Released in 2011, the HMZ-T1 was a visor-style HMD also known as the Sony Personal HD & 3D Viewer. It featured two miniature OLED displays, providing stereoscopic 3D imagery with 1280 x 720 resolution per eye. It used a proprietary video input and came with built-in stereo headphones. The external processor unit supported HDMI 1.4a and offered simulated 5.1 surround sound. The HMZ-T1 marked a shift towards 3D media consumption, offering a private 3D theater experience.

2012: Sony HMZ-T2 - Improved Technology

Released shortly after the T1, the HMZ-T2 featured enhanced comfort, a lighter design, and better 3D processing. It included early pass-through technology and a camera for mixed-reality experiences, hinting at future VR developments.

2013/2014: Sony HMZ-T3 - The Final Model

The 2013 HMZ-T3 featured dual OLED screens and 7.1 virtual surround sound. Available in two versions, the standard HMZ-T3 with wired HDMI and the HMZ-T3W with wireless HDMI, it marked the end of the HMZ series as Sony shifted focus to its VR headset, codenamed Morpheus, in 2015.

Sony's HMD exploration, especially through the Glasstron series, reflects its pioneering role in personal and professional viewing technology. These early displays were precursors to today's VR and AR systems, marking crucial steps in modern immersive technology.
