Immersive 3D visualization laboratory concept
In the paper an advanced concept for a Virtual Reality (VR) CAVE installation is presented, which should allow for human immersion in a spatially unlimited virtual world. The CAVE will be completed by the end of 2013 in a special building designed and constructed for the purpose. The unit will simulate an autonomous movement of a human inside a computer generated scenery. The person immersed in VR space will be placed in a transparent sphere with a large diameter supported on rollers and equipped with a motion tracking system. Walking motion of the person will inflict the revolution of the ball and trigger changes in the computer generated images on screens surrounding the sphere thus creating an illusion of motion. The projection system will be equipped with a 3D simulation capability and supplemented with a spatial sound generation system.
MAZIKOWSKI LAUNCH OF THE IMMERSIVE 3 D VISUALIZATION LABORATORY
The paper presents the concept of Immersive 3D Visualization Laboratory, formed at the Faculty of Electronics, Telecommunications and Informatics of the Gdańsk University of Technology under the Gdańsk University of Technology Modern Auditoriums project. The basic unit of this laboratory will be a cubic CAVE (Cave Automatic Virtual Environment) supplemented with a spherical walk simulator. This device will allow the user unlimited walking, and even running, in a freely created virtual world. If the virtual world becomes a battlefield or a burning building, this device will be able to serve as an infantry soldier simulator or fire-fighter simulator. The opening of the laboratory will take place in mid-2014.
Adolescent sexual offenders: incidence of childhood maltreatment, serious emotional disturbance, and prior offenses.
Adolescents incarcerated for sexual offenses were compared to those incarcerated for other crimes on measures of prior child abuse and neglect, serious emotional disturbance, and involvement in child welfare and the juvenile justice system. Sexual or physical abuse was more common than neglect among sexual offenders with fewer than three prior maltreatment reports. Sexual offenders were twice as likely to be receiving special education services for severe emotional disturbance, and were usually incarcerated later than other offenders. Implications for research and practice are discussed.
