A group of students in the Faculty Engineering and Computer Engineering of Aristotle University of Thessaloniki invented an innovative application which contributes to the early diagnosis of Parkinson disease. This is ‘Prognosis’ which has been designed for smartphones and it works in conjunction with a Microsoft Band. “By downloading this application, some data of the user’s interaction with the device are recorded as the change in the voice and the way of messages’ writing or the way of walking. In this way a mass of behavior data is created which is connected with the Parkinson’s symptoms”, Leontios Hadjileontiadis, who is the leader of the team and professor in the department of Aristotle University of Thessaloniki, states. After the data’s collection, ‘Prognosis’ processes them. This application also succeeds in improving the models of analysis and in the enrichment of data base in Cloud. “We carried the first place in Ability Award and the third place in World Citizenship Competition in the worldwide competition ‘Microsoft Imagine Cup 2015’ which took place in Seattle in the USA”, Mr Hadjileontiadis highlights and he also claims that this research project belongs to the European program Horizon 2020 – PHC 2015 (Personification of Health and Care). The team of ‘Prognosis’ is consisted of the students Despoina Efthimiadou, Dimitris Iakovakis, Konstantinos Mavrodis and Vasiliki Bikia.
