Improvements in Targeting Precision by Applying Pointing Corrections to a Computer Assisted Rehabilitation Environment (CAREN)
Abstract
The Computer Assisted Rehabilitation Environment (CAREN) at the Naval Health Research Center (NHRC) is an interactive virtual environment that has the ability to task subjects both cognitively and physically. The CAREN D-Flow software (Motek Medical BV, Amsterdam, The Netherlands) that allows the operator to create and control the scenarios has different modules from which to manipulate and monitor the hardware components, activate events, or record information. The Pointer3D module targets objects in a CAREN scene by extrapolating the position of two markers attached to a simulated weapon or other pointing device. The typical result has been that the projected target does not align well with the pointing markers, thus limiting the possibility of using the CAREN system for precision targeting such as in the case of a shooting simulator. The purpose of this paper is to apply effective targeting corrections in a manner that is portable between D-Flow applications and also maintainable for changing situations. The initial implementation of pointing corrections as described in this document produced favorable results overall for the NHRC CAREN. Targeting correction technique described in this paper offers credence that the CAREN could be used as an effective shooting simulator or at least incorporate realistic targeting within the CAREN software applications.
