PURPOSE To investigate the effect of virtual reality proficiency-based training on actual cataract surgery performance. The secondary purpose of the study was to define which surgeons benefit from virtual reality training. DESIGN Multicenter masked clinical trial. PARTICIPANTS Eighteen cataract surgeons with different levels of experience. METHODS Cataract surgical training on a virtual r...

Recent research suggests Virtual Reality Exposure Therapy (VRET) for the treatment of fear of flying as an important reliable technique for this phobia. This paper focuses on the role of the therapist during an exposure session. Six therapists were observed in 14 sessions with 11 different patients. Results show that in 93% of the observed sessions, therapists started with a similar flight patt...

This paper presents a new method for creating a 3D virtual broad city environment with walk-through systems based on Image-Based Rendering(IBR). In that virtual city, people can move rather freely and look at arbitrary views. The strength of our method is that we are able to easily render any view from an arbitrary point to an arbitrary direction on the ground in a virtual environment; previous...

BACKGROUND Flexible sigmoidoscopy, a core skill for the primary care physician, requires learned hand-eye skills that can be difficult to master during residency training. With recent advances in virtual reality simulation technology, simulated flexible sigmoidoscopes are available to family medicine residents for training before their initial and subsequent live patient examinations. The purpo...

This paper presents the simulation of humanoid walking pattern using 3D simulator with Virtual Reality Toolbox. 3D simulator is essential for developing motion planning and navigation algorithm. By using the Virtual Reality Toolbox incorporated with MATLAB, it is easy and simple to handle 3D objects. Detailed program architecture is explained through a pseudo code. In addition, modifiable walki...

This paper describes a highly interactive virtual reality orthopedic surgery simulator. The simulator can section, reposition and join volume-represented structures. By these functions, the simulator allows surgeons to use various surgical instruments to operate on virtual bones for simulating every procedure of complex orthopedic surgeries.

Each winter, Iowa Department of Transportation (Iowa DOT) maintenance operators are responsible for plowing snow off roads in Iowa. Drivers typically work long shifts under treacherous conditions. In addition to properly navigating the vehicle, drivers are required to operate several plowing mechanisms simultaneously, such as plow controls and salt spreaders. However, there is little opportunit...
