![]() ![]() In the rotoscope method, animators stood at a glass-topped desk and traced over a projected live-action film frame-by-frame, copying actors' or animals' actions directly onto a hand-drawn world. Rotoscoping was a primitive and time-consuming process, but it was a necessary starting point for the industry. It was 1915, in the midst of the First World War, when animator Max Fleischer developed a technique called rotoscoping and laid the foundation for today's cutting-edge mocap technology. Mocap was born a lifetime before Gollum hit the big screen in The Lord of the Rings, and ages before the Cold War, Vietnam War or World War II. Mark Elliott, ( or Carine Lewis, Client Relationship Manager ( to discuss opportunities.Modern motion-capture systems are the product of a century of tinkering, innovation and computational advances. We are keen to work with commercial partners in this area and can assist with both algorithm development and validation. We use our highly accurate 3D motion tracking facilities as a way of validating these new algorithms or providing labelled reference data in their development. This can involve developing algorithms for new (often wearable) sensing devices or validating the accuracy of the technology. Ī lot of our research is in collaboration with commercial partners developing healthcare technology solutions. Using this new device will avoid the need to screen all patients using x-rays, which would take up significant time and resources. Using a wearable sensor device, we have achieved high correlations to measures obtained using x-ray. Our research is investigating the development of a rapid screening tool to estimate pelvic mobility. standing, laying down, sitting) due to an increased risk of dislocation. Recent research has revealed that people due to have a replacement hip require more accurate planning of the positioning of the implant if their pelvis shows large changes in tilt angle between different positions (e.g. ![]() Measuring pelvic tilt for optimised hip replacement surgery.Our experiments involve measuring how well people can follow and mimic the movements of the avatar. We are using the motion capture system to accurately capture physiotherapy exercises and mapping these movements on to the virtual avatar. We are investigating whether virtual avatars can be used to provide guidance on physiotherapy exercises outside of the clinic. Virtual reality avatars for physiotherapy and rehabilitation.Examples of some of our projects using these facilities include: Much of our work uses these facilities for researching new technologies around orthopaedics, physiotherapy and rehabilitation. Research FocusĪt the Institute of Digital Healthcare, we are researching data and technology driven solutions for healthcare. These facilities are complemented by portable wearable devices, including motion sensing inertial measurement units (as found in smartphones/fitbits to measure the number of steps you’ve walked, and drones to measure their orientation and remain stable), ECG for measuring heart responses and EMG for measuring muscle responses. An indirect calorimetry system further allows accurate measurement of energy expenditure whilst participants complete movement tasks. The extended lab has a 14m walkway to capture people’s walking over a number of gait cycles, or alternatively, their continuous walking/running can be captured using a low-profile rehabilitation treadmill. The facility has both HTC Vive and Occulus VR headsets along with a Microsoft Hololens augmented reality headset. This allows full interaction with virtual environments, with an individual’s whole body being mapped into that environment. Using this system, we are able to feed realtime measurements of people’s movements into virtual reality (VR) environments. Using reflective markers attached to the person or object that is being tracked, the cameras measures and reconstructs the 3D motion in real-time at up to 300 frames per second. The lab uses the latest Qualisys Miqus 3D video camera system, with 10 cameras distributed around the room. The motion capture laboratory in WMG has the facilities to track the movement of people and objects in 3D space to an accuracy of 0.5mm. ![]()
