Scientific Applications

Use a PTI Motion Capture System for your research and take advantage of its unique features. Our VZ4000v systems are built for research and science. Depending on your field of research, some specific features may be more relevant to you than others. See below 10 simple questions to help you decide on what you need most from your Motion Capture System.

 

 

What do I need?

Here are 10 simple questions to consider. Do you need...

Our H-series VZ4000v trackers offer a 3D accuracy of < 0.50mm RMS and can detect a position change as small as 0.015mm (at 1.2m distance). Using 1-chip LED markers will give you the greatest precision, while automatic calibration (unique on the market!) will keep your trackers calibrated at all times and maintain capture data accuracy. For even larger capture space, more trackers can be added to join multiple capture spaces together.
All PTI trackers offer an exclusive 90-degree viewing angle. One SINGLE tracker can already capture targets over a 7x9m space! Using our 6-chip led markers with 170-degree detection angle will maximize the capture range.
Then you need the short VZ4050 tracker! Only 62cm in length, it can capture targets as close as 25cm, over a 90-degree viewing angle, both horizontally and vertically!
It is easy, and cost-efficient. Unique marker ID's ensure that no marker-swapping errors can occur. With only 4 trackers you can already capture simultaneously 2 subjects over a 7x9m space, in real-time! Even more subjects can be captured by expanding your system with additional trackers.
Capturing complex motions (for example: finger motions) together with whole body at the same time and without marker errors is an impossible task for most Motion Capture systems. Not for a PTI system, thanks to our unique marker ID's. You can capture intricate finger motion AND full body at the same time, with no errors, and use your data in real-time.
A PTI system is portable, flexible and autonomous. Portable because each tracker can be transported easily with its tripod, setup in minutes, and start to capture without any calibration. Flexible because trackers can be setup in anyway you like, no need to prevent them from facing each other, no need to aim them top-down either. Autonomous because marker swapping will never happen, and automatic calibration frees you from having to repeatedly calibrate the system manually!
PTI systems are developed for real-time applications, of course this means they are also good for non-real-time applications too. Besides being able to identify each marker uniquely, without any error, the data output latency is < 0.0005s, perfect for applications requiring instant data feedback. SDK is also available for the most demanding applications which must minimize the temporal effects of the computer OS.
Nothing is easier. A PTI system can be synchromized with any equipment, (Forceplate, EMG..) via a National Instruments board. You can also synchronize your trackers with an eye-tracking device, or high speed cameras.
Our systems come with complete operation software and motion analysis software. Plugins for Matlab, Labview, Visual 3D, The Motion Monitor are also available, as well as for other software.
Then you will enjoy using our haptic markers. These markers can send tactile stimuli in real time while capturing motions, allowing you to control or train a subject's motions by 'touch'.
