The COVID-19 pandemic period has renewed interest in touchless computing in healthcare. This is largely motivated by infection prevention and control, and an interest to now consult and remotely monitor patients in their own homes. Previous efforts to implement touchless computing have been limited by the expense and installation of new hardware, software requirements and assembly of solutions. I have been leading on University College London (UCL)'s MotionInput v2.0 supporting DirectX project with Great Ormond Street Hospital for Children, with the task set to our team of how to create a low cost and scalable method for enabling touchless computing for existing and new software, by using standard webcams.
UCL’s MotionInput v2.0 supporting DirectX is a modular framework with four modules of customised gesture tracking from a webcam using open-source libraries (hand gestures, head movement, eye tracking and exercise recognition). These are connected by a common Graphic User Interface (GUI) to enable Windows-based interactions on all existing PC software managed by DirectX, including games, creativity, office and especially healthcare applications. Human motion gestures, like hand and body motions, head and facial movement and eye tracking are mapped from an RGB webcam video stream to input commands for existing applications and games. It uses published open-source libraries in a federated and locally processed way.
System architecture of the prototype software
MotionInput v2.0 is designed to work across a broad range of contexts and with users of differing capabilities. Users can execute cursor commands – moving a cursor with their hands, eyes or head direction, perform mouse clicks with hand pinching, eye blinking and mouth opening gestures. They can scroll with a hand or head movement. Physical detection of exercises like squatting, jumping, cycling, air punches and kicks are also measured as inputs for DirectX. New contributions include an idle state for activating and deactivating gestures, a dynamic area of interest and depth variation captured from a 2D webcam.
It is with great pleasure that I showcase some of the features of this year’s version of the software, with UCL’s Industry Exchange Network (UCL IXN) in collaboration with Microsoft and Great Ormond Street Hospital for Children’s DRIVE Unit. I am so proud of the ingenuity of this year’s team of undergraduates and Master’s in Computer Science students and their achievements: Ashild Kummen, Guanlin Li, Ali Hassan, Teodora Ganeva, Qianying Lu, Robert Shaw, Chenuka Ratwatte, Yang Zou, Lu Han, Emil Almazov
