TutAR: augmented reality tutorials for hands-only procedures
TutAR is presented, a pipeline that semi-automatically creates AR tutorials of 2D RGB videos with hands-only procedures such as cardiopulmonary resuscitation (CPR), which extracts relevant 3D hand motion from the input video. Expand
A Wearable Vibrotactile Interface for Unfavorable Posture Awareness Warning
Evaluated the vibrotactile system with 11 subjects to identify the optimal notification vibration sequences and the accuracy of the location-dependent perception and results indicate that the optimal pulse length is about 150 ms and is repeated 2 or 3 times within the sequence for maximum attention.

Designing a New Puzzle App to Target Dyslexia Screening in Pre-Readers
The prototype of a puzzle app is presented, which is explicitly designed with the human-centred design (HCD) process for dyslexia screening in pre-reader using new indicators related to motor skills to ensure users needs for the data collection to apply machine learning prediction. Expand
Enhancing Safety of Artificially Ventilated Patients Using Ambient Process Analysis
An analysis system consisting of low-cost ambient sensors such as power sensor, RGB-D sensor, passage detector, and matrix infrared temperature sensor is proposed to reduce risks for artificially ventilated patients in both home and clinical environments. Expand
Cardiopulmonary Resuscitation Quality Parameters from Motion Capture Data using Differential Evolution Fitting of Sinusoids
A novel approach including sinusoid models that use skeletal motion data from an RGB-D (Kinect) sensor and the Differential Evolution (DE) optimization algorithm to dynamically fit sinusoidal curves to derive frequency and depth parameters for cardiopulmonary resuscitation training is presented. Expand
TutAR: Semi-Automatic Generation of Augmented Reality Tutorials for Medical Education
TutAR is a pipeline that semi-automatically creates AR tutorials out of 2D RGB videos that extracts relevant 3D hand motion from the input video and displays as an animated3D hand relative to the human body. Expand
Determining Cardiopulmonary Resuscitation Parameters with Differential Evolution Optimization of Sinusoidal Curves
In this paper, we present a robust sinusoidal curve fitting method based on the Differential Evolution (DE) algorithm for determining cardiopulmonary resuscitation (CPR) parameters – naming chestExpand
Unsupervised Temporal Segmentation of Skeletal Motion Data using Joint Distance Representation
An online method for the unsupervised segmentation of skeletal motion capture data for the assessment of unfavorable or harmful postures in the context of musculoskeletal disorders and results show that the algorithm approaches the performance of state-of-the-art offline segmentation algorithms.
