Periodic Reporting for period 2 - See Far (Smart glasses for multifacEted visual loss mitigation and chronic disEase prevention indicator for healthier, saFer, and more productive workplAce foR ageing population)

Reporting period: 2020-06-01 to 2021-11-30

See Far is a digitally enabled adaptive solution supporting ageing workforce with vision deficiencies, an age-related condition, to remain actively involved in professional life, helping them to sustain and renew their work and personal life – related skills and support an independent active and healthy lifestyle. This is a low-cost unobtrusive solution, which ensures the creation of an adaptive smart working and living environment, since it contributes to its four key elements: physical health, ergonomics/environment, technology and management practices.
The See Far solution consists of two main components:
- The See Far smart glasses, that are adapted to the needs of the users and optimize their vision by employing a personalized visual assistant that captures the condition of the eye, detects the problem and provides the appropriate adjustment through the integration of augmented reality technologies.
- The See Far mobile application, which allows monitoring of the central vision evolution and prediction of the risk for the presence of diseases (e.g. diabetes risk, cardiovascular risk). It will capture retinal images, through a digital direct
ophthalmoscope attached to the smartphone, analyse them, and estimate the type and the stage of vision impairment, by employing machine learning techniques.
The combination of the output of the See Far mobile application (indicator of the presence of a visual problem, or not), with that of the See Far smart glasses (type of daily visual issues the user has and his/her behaviour), will lead to the provision of suggestions/assistance, through augmented reality, to the user, supporting an independent, active and healthy lifestyle. The suggestions/assistance provided will be adapted to the profile of the user, through the personalised visual recommendation service. A combination of state-of-the-art techniques from the fields of computer vision, augmented reality and artificial intelligence will be employed in order to achieve the challenging objectives of the See Far Project.
From the start of the project to the end of the reporting period (M01-M36), the See Far Project consortium has been working to achieve the project objectives as stated in the DoA. All scheduled deliverables have been submitted and all milestones have been met:

WP1: Special attention has been paid to teamwork and coordination, and to redefine the project to address the issues arisen (especially COVID-19). 6 plenary meetings and 29 monthly regular PCT meetings were held. The Periodic Reports were submitted, and the project reviews were carried out (“satisfactory implementation”). 2 amendments were requested and accepted.
WP2: The final version of the design of the solution, (SeeFar architecture, Functional and Non-Functional Specifications and User Requirements), was delivered in Dec 2020. User centric design approach activities involving patients and employers included many activities such as open questionnaire, 3 focus groups, etc. A first version of the design (user requirements, architecture, F&NF specifications) was prepared.
WP3: The functionalities defined for the smart glasses (magnification, filters, recommendations, indoor and outdoor navigation, etc.), personalized profile (medical, behavioral, etc.), estimation of the user condition (emotional, cognitive, etc.), some supporting features (object and activity recognition, etc.) and the gaze tracking system (the basis for some features) have been developed.
WP4: The PCB, sensors, holding frame, processing units, selection and integration of COTS components, wireless power supply unit, etc. were developed, involving many areas of expertise. The smart glasses electronic solution was delivered.
WP5: The definition of the testing strategy, tools to be employed, test plans, test procedures, etc. Prot. C was presented in the RV1 meeting (Aug 2020). Prot. D was presented in the 2nd interim review (May 2021).
WP6: The consortium addressed the authorizing bodies and any related difficulties. In May 2021, the new versions of the protocol were approved by the local ethics committees in both sites (DK, ES).
WP7: Website, search engine optimization, social media accounts and interaction with the users, newsletter, mailing lists, infographic and specific content were developed. Several scientific publications were submitted. The plans for dissemination, exploitation and IPR management are important outcomes of this WP.
WP8: WP8 outstanding deliverables were submitted.
Progress beyond the state of the art
- See Far smart glasses combine the advantages and the functionalities of the available in the market products or prototypes and moves one step forward since it will be an unobtrusive, adaptive solution for age-friendly living and working environments, addressing the needs of employees with vision deficiencies in any sector and workplace.
- See Far smart glasses will provide personalized feedback and support due to the personalized profile mechanism. They will recognize the time and the type of the support that the user needs (Intelligent component) and they will activate the Personalized visual assistant, Personalized recommendation service and or Embedded navigation system, accordingly.
- See Far mobile application will extend the D-EYE Portable Retinal Imaging System in order to allow, not only mobile recording of retina images, but also the analysis of these images and the detection and prognosis of different retina diseases. State of the art machine learning techniques will be employed in the existing system in order the specific objective to be achieved.. See Far mobile application will be an innovative, non-invasive, user friendly, convenient and ergonomic, portable, monitoring, diagnostic and prognostic tool.
- See Far solution will allow the prediction of different impairments through the analysis of retina images received by a portable ophthalmic camera attached to the Smartphone of the user.
- See Far solution will utilize the above mentioned behavior modeling techniques and it will focus on the fusion of the dynamic and heterogeneous sources of information that will be recorded.
- See Far visual recommendation service, taking into consideration the personalized profile of the user and his/her behavior will motivate the user to adopt behaviors that allow him/her to remain actively involved in professional life, to sustain and renew their work and personal life related skills and support independent active and healthy lifestyles.

Expected impacts
- Independent living, and quality of life of older persons compared to current state of the art, enabling older persons to stay actively involved in work life for longer or return to work after severe disease.
- Enhanced health and safety working conditions and quality of life of older persons at work compared to the current situation, enabling older persons to be able to contribute for a longer period of time.
- Evidence of user-centred design, new ways of human-computer interaction, and user acceptance.
- Potential cost-effectiveness due to enhanced self-care, life-style, age-friendly and skills conducive work environments
- Competitive advantage for European industry through flexible and sustainable work arrangements for an ageing workforce. and socio-economic benefits.
- Global leadership in ICT for active and healthy ageing including the occupational environment.
