Virtual reality (VR) holds great promise for the study of perception-action. The case of studying the outfielder problem is presented as an example of how VR has contributed to our understanding of perception-action, and of the potential and pitfalls of using VR in such a task. The outfielder problem refers to the situation in a baseball game (and analogous situations) in which an outfielder has to run to get to the right location at the right time to make a catch. Several experimental studies are discussed in which participants had to intercept real or virtual balls. The biggest added value of using VR is the fact that the virtual world is completely in the hands of the experimenter, which allows studying situations that do not exist outside of VR, thus enabling strong hypothesis testing. A number of factors related to the success of the VR experiments are identified, such as the lack of haptic feedback in VR setups used in this paradigm until now, the specifics of the optics presented to the participants, and the available space for locomotion. We argue that it is important to make a close comparison of task behavior in VR with that outside of VR, but conclude having great expectations of the role of VR in perception-action research.

Neuromuscular deficits described in early childhood as motor awkwardness or slow movements are still clinically present in school-aged boys with XXY and XYY sex chromosome aneuploidy. A control group of 14 boys (6 to 19 years of age) and 14 XXY and four XYY boys (6 to 15 years of age), identified by newborn screening, were blindly evaluated by a physical therapist. The Bruininks-Oseretsky Test of Motor Proficiency (BOTMP) was administered and a clinical rating of neurologic status and sensory-motor integration was assigned. On the motor proficiency test, the XXY boys had significantly lower mean scores for upper limb coordination, speed and dexterity, and on gross motor and battery composites. The neuromuscular status of the aneuploid boys was deficient, with hypotonia, apraxia, primitive reflex retention, and problems with bilateral coordination and visual-perceptual-motor integration. This mild to moderate dysfunctional sensory-motor integration, as well as previously described auditory-processing deficits and dyslexia, contributed to school performance below that expected from their cognitive potential.

AbstractThe design and verification of assembly operations is essential for planning product production operations. Recently, virtual prototyping has witnessed tremendous progress, and has reached a stage where current environments enable rich and multi-modal interaction between designers and models through stereoscopic visuals, surround sound, and haptic feedback. The benefits of building and using Virtual Reality (VR) models in assembly process verification are discussed in this paper. In this paper, we present the virtual assembly (VA) of an aircraft turbine engine. The assembly parts and sequences are explained using a virtual reality design system. The system enables stereoscopic visuals, surround sounds, and ample and intuitive interaction with developed models. A special software architecture is suggested to describe the assembly parts and assembly sequence in VR. A collision detection mechanism is employed that provides visual feedback to check the interference between components. The system is tested for virtual prototype and assembly sequencing of a turbine engine. We show that the developed system is comprehensive in terms of VR feedback mechanisms, which include visual, auditory, tactile, as well as force feedback. The system is shown to be effective and efficient for validating the design of assembly, part design, and operations planning.
