The NVIS nVisor SX60 is a professional head-mounted display (HMD) for virtual reality applications, released in 2003 by NVIS Inc.[1][2][3]. Priced at $24,000 at launch, the device was designed for high-end military, industrial, and research applications, representing state-of-the-art technology for its time[4].

Overview

The nVisor SX60 was positioned as a high-resolution professional VR headset, incorporating advanced microdisplay technology and custom optics. The "SX" designation stands for SXGA resolution, while "60" refers to the 60-degree diagonal field of view[5]. The headset promised a collimated optics design to minimize eye strain and deliver superior image quality for professional applications[6].

Technical Specifications

Display Technology

The nVisor SX60 utilized dual reflective LCOS (Liquid Crystal on Silicon) display panels[3]. LCOS' sequential-color drive eliminates sub-pixels, producing a continuous "film-like" image that avoids the screen-door effect[1]. The device featured:

Display Specifications
Parameter Value
Display type Dual reflective LCOS
Resolution 1280×1024 pixels per eye (SXGA standard)
Refresh rate 60 Hz (VESA SXGA)
Brightness 30 foot-lamberts
Contrast ratio 100:1
Spatial resolution 2 arc-minutes per pixel
Color Full color microdisplays

Optical System

The headset employed custom engineered aspherical lenses with the following specifications[3]:

  • Exit pupil: 9 mm
  • Eye relief: 23 mm (allowing use with prescription glasses)
  • Geometric distortion: < 15%
  • Focus/Convergence: Collimated at infinity
  • Stereoscopic 3D capability

Field of View

The nVisor SX60 offered:

  • Diagonal field of view: 60 degrees
  • Horizontal field of view: 44 degrees
  • Vertical field of view: 35 degrees

Physical Specifications

  • Weight: 1000 g (headset only)
  • Inter-pupillary distance (IPD) range: 53-72 mm (manual adjustment via slider)
  • Cable length: 4.5 m tether
  • Adjustable head-fitting apparatus for comfort and balance

Tracking Capabilities

The nVisor SX60 featured 3 degrees of freedom (3DoF) tracking as standard, with support for 6 degrees of freedom (6DoF) through external tracking systems[2]. The headset included mounting points (both internal and external) for various tracking solutions:

Supported Tracking Systems
Category Supported Solutions Tracking Type
Inertial tracking InertiaCube 2, 2+, 3 3-DoF orientation
Optical tracking InterSense IS-300, IS-900 6-DoF positional
Magnetic tracking Ascension Flock of Birds, 3D-Bird 6-DoF positional
Passive markers ART "Tree Target SX60" Custom retro-reflective frame
Eye tracking Viewpoint Binocular/Monocular Eyetracker Optional accessory

Update rates could reach up to 180 Hz depending on the tracking system used[7].

Connectivity

The headset connected to PCs via[8]:

  • Video inputs: DVI (digital) or VGA (analog)
  • Control port: RS-232 for firmware upgrades
  • Graphics requirement: Dual monitor configuration support (2560x1024 combined resolution in horizontal span mode)
  • Compatible with NVIDIA graphics cards supporting "horizontal span" mode

Video Control Unit

The nVisor SX60 was typically paired with an Advanced Video Control Unit that provided[9]:

  • Plug-and-play support for analog and digital video inputs
  • Stereo and monoscopic output modes
  • Analog and digital monitor output repeater functionality
  • Optional battery for portable use

Applications

Due to its collimated optics and high resolution, the nVisor SX60 was primarily used in:

  • Military and Defense
    • Flight simulation and training
    • Target acquisition research
    • Dangerous scenario training for U.S. Army and NATO partners[3]
  • Industrial Applications
    • CAD visualization
    • Engineering design review
    • Industrial training simulations

Software Support

The headset was supported by various VR development platforms, including:

  • Vizard VR toolkit - included a dedicated nvis module for proper stereo and projection settings[8]
  • Custom military and industrial simulation software
  • Consumer software demonstrations including *Half-Life 2*

Reception and Legacy

Academic reviewers praised the display clarity and image quality but noted the limited field of view compared to later consumer headsets[6]. A 2015 University of Wisconsin comparison found the SX60's 60 Hz refresh "serviceable" but inferior to modern 90-120 Hz systems[10].

At its release in 2003, the nVisor SX60 represented cutting-edge VR technology, offering features that remained unmatched in the consumer space for over a decade[1]. The $24,000 price tag kept it firmly in the professional market, but its influence on VR development was significant.

The nVisor SX60 was succeeded by the nVisor SX111, which offered an improved 111° diagonal field of view while maintaining the same resolution[11].

Company History

NVIS Inc. was a major player in the professional VR space throughout the 2000s and early 2010s, developing numerous products for military, industrial, and commercial organizations. The company specialized in high-performance HMD solutions when consumer VR was virtually non-existent. In 2017, NVIS was acquired by Kopin Corporation, a leader in wearable display technologies. All NVIS products and support are now handled through Kopin's Training & Simulation division[12][13].
