In the past decade, the increasingly widespread use of mobile computing devices equipped with HD digital cameras and touchscreen electronic visual displays and sensors, such as smartphones and tablets, have enabled new methods for software developers to create applications for the real-time monitoring and early warning of cardiovascular and diabetic disorders. There has been a particular focus on the use of smartphone digital cameras for measuring blood pressure and blood glucose levels. The similarities in the tools, methods and parameters for the measurement and diagnosis of various types of medical disorders have paved the way for creating multipurpose medical applications. This research aims to identify the opportunities for convergence in medical smartphone applications that are enabled by recent technological developments; and the methods, technologies and platforms through which they can exchange data with online hospital information systems, for the purpose of providing real-time patient data to physicians in remote locations.
