Video game controller

The Army has developed a video game control system that will allow a player’s body movements to be automatically replicated on a video screen. This addresses a need in the market for an affordable virtual reality game system that uses the dynamic motion of a player to simulate a real-world experience in a video environment.

The technology does not require extensive or exotic computing resources as it is perfectly operational with a conventional PC interface and requires only standard keyboard and mouse connectors.

Improved head-related transfer functions (HRTFs)

Air Force researchers have developed a novel head-related transfer function (HRTF) enhancement technique that systematically increases the salience of the direction-dependent spectral cues that listeners use to determine the elevations of sound sources.

The HRTF filters produce virtual sound sources over stereo headphones with more robust elevation localization performance than can be achieved with the current HRTF-based virtual audio display systems.

Users of this technology may be aircraft pilots, unmanned aerial vehicle pilots, virtual reality players, scuba divers, parachutists, and astronauts.

Personalized 3D rendering of audio signals

An Air Force engineer has improved the process for building a personalized 3D audio experience using head-related transfer function (HRTF) filtering effects.

This method will create very realistic auditory virtual realities for entertainment, gaming, and e-tourism purposes, as well as for more serious applications like education and training, remote telepresence, and spatial situation awareness displays.

If virtual audio signals are replaced with physical loudspeakers (or virtual simulations based on the device/settings), then the system may be used to select appropriate, commercially-available hearing aids, hearing protectors, communication headsets, or settings.

LIDAR created, millimeter accurate virtual environment mapper

A Navy scientist recently invented a system for rapidly scanning a complex environment, generating interactive 3D models, and cutting and pasting new objects into the virtual environment.

The virtual environment can be employed to create repeatable and verifiable measurements for remodeling and installation planning, as an interface for collaboration between design teams, as an intuitive way for engineers to identify installation discrepancies before making structural changes, and as an environment for virtual training with new installation equipment before it is even physically placed.

The accuracy and resolution provided by the 3D model make the technology further appropriate for configuration management, legacy part capture, generating as-built diagram requirements, installation diagrams, and the creation of virtual reality environments for marketing and sales offers.
