Abstract: In this paper, we describe the design of a visual interface of a mobile a mobile app for tracking nutrients and foods consumed by patients with Parkinson’s disease. The interface should enable the patients to recognize objects on the screen, easily perceive their function and interact with them thus providing an efficient way of entering the dietary intake data. The app has been validated by five patients and the preliminary results are encouraging.

Abstract: The aim of the article is to show how off-the-shelve equipment can be used to develop serious games for an affordable tele-medicine solution for Parkinson’s disease management. Two games have been developed aimed at assessing and training patient’s reach of upper limbs (using Kinect v2) and fine motoric skills of fingers (using Leap motion). The games collect player data in terms of score achieved and full kinematics of movement during gameplay. The data is stored online and made available to therapists and doctors through a secure connection. The games have been tested with patients within the Soča rehabilitation institute as well as at their homes.

Abstract: In this paper we present a novel integration of four remote collaboration modalities into an existing web-based medical data visualization framework: (1) visualization data haring, (2) camera view sharing, (3) data annotation haring and (4) chat. The integration of remote collaboration modalities was done for two reasons: for getting the second opinion on diagnosis or for getting a diagnosis from the remote medical specialist. We present an integration of these modalities and a preliminary evaluation by the medical expert. In conclusion we show that we are on the correct track of integrating collaboration modalities into the visualization framework.

Multi-Touch surface based on RGBD camera

Abstract

The popularity of interactive surfaces is increasing because of their natural and intuitive usage. Adding 3D multi-point interaction capabilities to an arbitrary surface creates numerous additional possibilities in fields ranging from marketing to medicine. Interactive tables are nowadays present in numerous museums, schools and companies. With the advent of low-cost RGBD cameras, thee-dimensional surfaces are slowly emerging as well, attracting even more attention. This paper presents an affordable system for 3D human-computer interaction using a RGBD camera that is capable of detecting and tracking user’s fingertips in 3D space. The system is evaluated in terms of accuracy, response time, CPU usage, and user experience. The results of the evaluation show that such low-cost systems are already a viable alternative to other multi-touch technologies and also present interesting new ways of interaction with a surface-based interfaces.

Toward improved emergency call service: a usability test case study

Posted on by

Miha Ristič & Franc Novak

Abstract

This paper describes the initial steps for the improvement of emergency call service. For instance, persons reporting an accident or similar event and the officer receiving the call are often under stress, which distracts the communication process and becomes a barrier to information transfer. We try to identify the main deficiencies when processing a received call and explore alternative ways of recording the main information content. In this regard we performed a usability test case study for assessing the efficiency of recording information either on a blank paper or in a prepared paper form. Implementation details of the usability test are described.

How to provide health-related information by mobile computing?

Posted on by

Barbara Koroušić Seljak

Abstract

The paper describes an approach taken by a mobile application eDietetik for the presentation of health- related information that is not allowed to be provided as a health claim. In this case, a mobile device running the application interacts with consumers, translating health-related information in an understandable and unambiguous way. Moreover, it may present an interface between different human stakeholders (i.e. consumers and manufacturers, consumers and healthcare providers, manufacturers and policy-makers).

Wireless medical device audio alarm

Posted on by

Marko Pavlin

Abstract

Audio alarming system for medical devices requires attention at some very specific segments. The clinical environment is full of disturbances and every alarm sound is not an exception. This paper presents some aspects of (audio) alarming within clinical environment and associated problems. Low power operation and limited resources for implementation are just on top of the problems related to the user experience. The presented solution is following the specific standards and is flexible enough to provide audio signals, which can be generated with small microcontroller. The described alarm generator was evaluated in laboratory and during clinical evaluation in real clinical environment with patients. The results are presented at the end of the paper.
