Placement of pre-contoured fixation plate is a common treatment for bone fracture. Fitting of fixation plates on fractured bone can be preoperatively planned and evaluated in 3D virtual environment using virtual reality technology. However, conventional...

The need of health and social care for community-dwelling elderly is on the rise as population ages. Through the provision of comprehensive services by multiple professionals in local communities, elderly people receive continual care in a non-medical...

Background: Recent studies have revealed lifestyle behavioral risk factors that can be modified to reduce the risk of dementia. As modification of lifestyle takes time, early identification of people with high dementia risk is important for timely intervention...

Background: Wound care is an essential nursing competency, where dressing change is an important component. Compliance with aseptic procedures and techniques is necessary to reduce the risk of infection. Proficiency in the skills can be developed through...

The use of personal protective equipment  is one of the basic infection control precautions in health care. The effectiveness of personal protective equipment  is highly dependent on adequate staff training. In this project, a computer simulation pro...

Missing data is a common issue in community health and epidemiological studies. Direct removal of samples with missing data can lead to reduced sample size and information bias, which deteriorates the significance of the results. While data imputation...

Bladder cancer is a common cancer in genitourinary malignancy. For muscle invasive bladder cancer, surgical removal of the bladder, i.e. radical cystectomy, is in general the definitive treatment which, unfortunately, carries significant morbidity...

Conventional anatomy education makes use of two-dimensional (2D) images of three-dimensional (3D) anatomical objects to illustrate their spatial locations and interrelationships. Good visual-spatial ability is needed to mentally transform or fuse multiple...

Nasogastric tube (NGT) placement is a common clinical procedure where a plastic tube is inserted into the stomach through the nostril for feeding or drainage. However, the placement is a blind process in which the tube may be mistakenly inserted into...

Virtual Reality Based Rehabiliation Training of Activites of Daily Living with Force Feedback Aim The aim of the project is to provide a computerized training system for physically disabled people to practice the manual skills in various activities...

Students with upper extremity disabilities often face barriers to learning mathematics which is largely based on handwriting. While they may instead use computers to do mathematics, conventional input methods using keyboard and mouse do not cater for...

This paper presents the development of a low-cost cataract surgery simulator for trainees to practise phacoemulsification procedures with computer-generated models in virtual environments. It focuses on the training of cornea incision, capsulorrhexis...

Purpose To investigate whether the provision of force feedback as guidance in a computer-assisted training environment was feasible for improving handwriting ability of children with cerebral palsy.    Method Two children at the age of 7, d...

Clinical data are dynamic in nature, often arranged hierarchically and stored as free text and numbers. Effective management of clinical data and the transformation of the data into structured format for data analysis are therefore challenging issues...

Development of virtual-reality medical applications is usually a complicated and labour intensive task. This paper explores the feasibility of using commodity physics engine to develop a suturing simulator prototype for manual skills training in the fields...

Research on collaborative virtual environments (CVEs) opens the opportunity for simulating the cooperative work in surgical operations. It is however a challenging task to implement a high performance collaborative surgical simulation system because of...

Serious games are computer games used for applications unrelated to entertainment or traditional games. Application domains include areas such as flight or driving training, military operations, education, surgery, and general healthcare. Although...

Purpose To motivate children with intellectual disabilities to learn handwashing and improve their performance by using computer-assisted teaching method. Method A teaching program was implemented using a computerized teaching station with faucet,...

Misconceptions about psychiatric wards frequently cause newly admitted mental patients to stay away from these wards despite their need for treatment. Although ward orientation is typically conducted by nurses in an attempt to help patients to adapt...

Modeling of tissue deformation is of great importance to virtual reality based medical simulations. Considerable effort has been dedicated to the development of interactively deformable virtual tissues. In this paper, an efficient and scalable deformable...

An effective deformable model based on a successive force propagation process is proposed. It avoids the laborious stiffness matrix formulation and is scalable simply by controlling the penetration depth. Mechanical tests are performed to evaluate...
