The D-Flow software is a visual programming tool designed for the development of interactive and immersive virtual reality applications, for the purpose of clinical research and rehabilitation. The D-Flow software system allows an operator to define feedback strategies through a flexible and extensible application development framework, based on visual programming.
D-Flow is based on the concept of modules: manageable components with a specific functionality, which can be combined to create complex, interactive virtual reality applications. There are various types of modules present in the D-Flow software system. Some modules directly control specific hardware devices, such as a treadmill or a motion base. Other hardware modules provide access to real-time data streams from live input devices or control the virtual environment.
The D-Flow software system allows an operator to define feedback strategies through a flexible and extensible application development framework, based on visual programming.
Key to the D-Flow software is that the subject is regarded as an integral part of a real-time feedback loop, in which multi-sensory input devices measure the behavior of the subject, while output devices return motorsensory, visual and auditory feedback to the subject.
The D-Flow software platform has integrated many different hardware devices, ranging from infra-red motion capture cameras, 6-degree of freedom platforms and dual belt treadmills to inertia sensors and haptic devices. Many of the Motekforce Link products are powered by the D-Flow software, like CAREN, GRAIL, DynSTABLE and M-Gait.
Fast Feedback Loop
Balancing a small stick in the palm of your hand requires the brain to interpret the movement of the stick, choose a counter movement and execute this movement before the stick reaches a critical point. The video on the right shows just how we are able to perform this task using the D-Flow software, motion capture and a motion base.
