Infrastructure-based EGNOS/Galileo receiver for personal mobility
Background & Objectives
The number of accidents happening to the elderly and handicapped people has dramatically increased over the last few years. At present in Europe there are approximately 4 million people suffering from Alzheimer’s disease. Elderly people and especially people with Alzheimer’s disease very often get into situations where they become disoriented. They need support from either their family members or nursing staff.
IEGLO incorporates seamless indoor and outdoor positioning and emergency call services for healthcare applications.
Special software on the mobile device evaluates inertial data from sensors, and detects falls and cases of sudden collapse. In these situations the software triggers an automatic alarm together with the current position and infrastructure-based data. The alarm message is broadcast by cellular networks to the positioning server which combines all the information and estimates the position accuracy. For data privacy protection reasons, the integrated but anonymous position is forwarded to the application server. In the case of an emergency, the separated application server combines the anonymous position data with personalised data. A web-client displays the position, type of alarm, personal data and mobile number of the device. For a first response the web-client enables an enquiry call to check the patient’s situation.
In the vicinity of dangerous areas, the position data is processed together with EDAS data on the server side to form integrity information and an augmented position. This processing technique is necessary as most of the mass-market mobile devices are not EGNOS enabled.
The complete system is administrated by an intuitive MMI (man-machine interface) to handle devices, personal staff lists, GEOCorridor® and alarm messages. The MMI provides flexibility for customising and can be used in geriatric clinics as well as in sheltered accommodation.
The objective of IEGLO is to develop a complete demonstrator system which allows supporting the elderly and Alzheimer sufferers in emergency cases using a small, lightweight mobile device.
Special software within the device processes inertial sensor data and detects falls, sudden collapse or motionless situations. An automatic alarm informs family members or nursing staff. Besides this automatic alarm feature, an easy-to-use alarm button enables self-triggered emergency events.
(A)GNSS, together with WLAN and RFID technologies, will be implemented as seamless positioning for indoor and outdoor use. Further EDAS data is processed within the system for increased position accuracy. The position augmentation is triggered by GEOCorridor® and enables a unique position accuracy of the mobile devices in dangerous areas.
An intuitive web-client displays in case of emergency situations the position and time with the corresponding type of emergency case on a map. Individual areas defined in GEOCorridor® will set up protection areas like parks and areas for walking. Entering or leaving a protection area initiates an alarm and the person can then be found.
The IEGLO system is designed to integrate several types of mobile devices with different features for individual support. Two different test beds will be used for evaluating the demonstrator and providing professional feedback.
Work performed & results
The IEGLO system enables senior citizens to increase their mobility. The indoor and outdoor system guarantees help quickly in emergency situations. Elderly people can feel secure in wider areas and can extend their mobility for a more comfortable and recreational life. There will be no need for support and supervision by either their family members or nursing staff around the clock every day. In addition, living in familiar surroundings will be possible thus helping to reduce costs in the healthcare system.
Additional to the project reports, the results from IEGLO will be published in flyers and disseminated via public presentations. The basic demonstrator was shown at the health fair Intersana 2009 in Augsburg (DE). Several interviews and discussions during Intersana led to articles in newspapers and videos on Bavarian Television. The IEGLO system will be presented at the Galileo Application Days in Brussels.
