The newly developed gait trainer allows wheel-chair-bound subjects the repetitive practice of a gait-like movement without overstressing therapists. The device simulates the phases of gait, supports the subjects according to their abilities, and controls the center of mass (CoM) in the vertical and horizontal directions. The patterns of sagittal lower limb joint kinematics and of muscle activat...

This thesis presents a novel virtual reality (VR) training concept that integrates the trainer or the trainer model into training sessions. As an extension to conventional VR training systems that rely only on realistic interaction, the students are given the chance to be corrected by the trainer in a multi-user schema. The trainer is connected to the same virtual environment as the student via...

VRaptor, a VR system for situational training that uses trainer-defined scenarios is described. The trainee is represented b y an avatar; the rest of the virtual world is populated b y virtual actors, which are under the control of trainer-defined scripts. The scripts allow reactive behaviors, but the trainer can control the overall scenario. This type of training system may be very useful in s...

PURPOSE We examined the face, content and construct validity of version 1.0 of the University of Washington transurethral prostate resection (TURP) trainer. MATERIALS AND METHODS Version 1.0 of a virtual reality based simulator for transurethral skills was developed at our laboratory by integrating TURP hardware with our virtual 3-dimensional anatomy, irrigation control, cutting, bleeding and...

The aim of this study was to clarify the dentoskeletal treatment effects induced by a preorthodontic trainer appliance treatment on Class II, division 1 cases. Twenty patients (10 girls and 10 boys, mean age 9.6 +/- 1.3 years) with a Class II, division 1 malocclusion were treated with preorthodontic trainer appliances (Myofunctional Research Co., Queensland, Australia). The patients were instru...

Robotic devices are being developed to automate repetitive aspects of walking retraining after neurological injuries, in part because they might improve the consistency and quality of training. However, it is unclear how inconsistent manual training actually is or whether stepping quality depends strongly on the trainers' manual skill. The objective of this study was to quantify trainer variabi...

In this document, we will describe selected game aspects of a cognitive trainer game product. The cognitive trainer, developed by ACE, is targeted on basketball and hockey players. It enables them to improve their cognitive skills using an electronic game.
