Momiras aims to fulfill the expectations and needs of the market for the next generation of AR-enabled application and services by providing a complete set of tools that would both improve currently supported 3D augmented reality features and would expand them by utilizing novel technologies and algorithms (e.g. adaptive scene interactions, interaction simulation engine utilizing audio-visual cues for optimized immersive experience, etc.).

Developed AR-related algorithms for user-perspective view, illumination estimation, dynamic simulations, and gesture recognition, targeted at mobile devices.

Managed design and planning of major project components and handled communication with project partners and distributed teams. Designed extendable cross-platform core processing module interfaces and architecture. Developed innovative real-time RGB-D image processing algorithms for user-perspective view in video see-through devices (tablets). Developed high-performance illumination conditions estimation algorithms for cohesive augmentation and photorealistic rendering. Ιntegrated dynamic simulation functionalities and other sub-modules to core module API. Developed Android apps that showcase the platform’s features and functionality.

FrailSafe aims to better understand frailty and its relation to co-morbidities; to identify quantitative and qualitative measures of frailty through advanced data mining approaches on multiparametric data and use them to predict short and long-term outcome and risk of frailty; to develop real-life sensing (physical, cognitive, psychological, social) and intervention (guidelines, real-time feedback, augmented reality serious games) platform offering physiological reserve and external challenges; to provide a digital patient model of frailty sensitive to several dynamic parameters, including physiological, behavioral, and contextual.

Managed planning and communication with clinical partners, cross-functional, and distributed teams for major project tasks.

Developed cross-platform AR games for optical see-through HMDs and tablets. Developed wireless communication modules for custom hardware (Bluetooth/Wi-fi for Android and Windows) and external sensor components.

myAirCoach project aims to support asthma patients to control their disease through mHealth. New monitoring approaches, combined with the development of novel sensors, will form a system that will address the needs of patients on a daily basis. Analysis, modeling, and prediction of disease symptoms will serve to stimulate patients to engage in health management, and also increase the knowledge about the possibilities that mHealth can bring to asthma control.

Developed patient-specific lung simulation models for asthma severity assessment.

Key responsibilities:
• Development of triangulated 3D lung model processing module.
• Successfully developed adaptive bronchi-narrowing algorithms, aimed at asthma simulation tests.
