            Patients who survive head and neck cancer (HNC) face significant physical, psychological, and socioeconomic burdens. Achieving cancer-free survival while maintaining a high quality of life (QoL) is a key objective in the management of HNC patients, making lifelong monitoring essential.

            A particularly ambitious goal is the implementation of this monitoring through advanced analysis of environmental, emotional, and behavioral data, discreetly collected via mobile devices.

            This clinical study aims to reduce the proportion of HNC survivors — who completed their treatment between 3 months and 10 years earlier — experiencing clinically significant deterioration in quality of life during follow-up, using non-invasive tools such as patients’ mobile devices.

            The Big Data for Quality of Life (BD4QoL) study is an international, multicenter, randomized (2:1), open-label trial. The primary objective is to assess clinically significant deterioration in quality of life based on the EORTC QLQ-C30 score during a 24-month post-treatment follow-up period. The total sample size is 420 patients.

            Participants are randomly assigned either to the BD4QoL monitoring group or to the group receiving standard clinical care. The BD4QoL platform includes an integrated set of services for patient monitoring and empowerment through two main tools:

          • mobile application installed on participants’ smartphones, including a chatbot for e-coaching,
          • Point of Care dashboard used by researchers to manage patient data.


          • In both groups, participants complete QoL questionnaires at baseline and every six months, while also following the standard post-treatment clinical follow-up protocol.

            Patients in the intervention arm (n=280) gain access to the BD4QoL platform, while those in the control arm (n=140) do not. Key inclusion criteria include completion of treatment for non-metastatic HNC and use of an Android smartphone, while exclusion criteria include ongoing treatment or concurrent cancer diagnoses.

                              The McKercher typology is used as the research foundation, categorizing cultural heritage visitors into five main groups. Through the use of a specially designed questionnaire, an enhanced typology of cultural tourists is developed, in which three additional categories are introduced based on users’ preferences regarding multimedia content.

                              The proposed approach contributes to the creation of more personalized and interactive cultural experiences, enhancing visitor engagement and interaction within cultural routes and heritage environments.
                              Redefining Smart Tourism through Smart Gamified and Gaming Applications in Greece
                                World Academy of Science, Engineering and Technology – International Journal of Social and Business Sciences
                                Vol. 15, No. 01, 2021

                                Smart technologies are increasingly being used to enhance the travel experience and shape the image of a destination through digital applications and social media platforms. This paper presents the design and implementation of smart management applications that promote culture, sustainability, and accessibility in two different tourist destinations in Greece.

                                The first case concerns Corfu, a highly popular destination and UNESCO World Heritage Site, where high visitor demand creates challenges in terms of experience organization and infrastructure management. The second concerns Kilkis, a low-tourism and highly seasonal destination, where traditional cultural promotion and local experience strategies have not produced the desired results.

                                To address these challenges, two different systems were developed:

                              • “Hologrammatic Corfu” for the old town of Corfu,
                              • “BRENDA” for the Kilkis region.


                              • Although the two systems were designed independently and address different needs, they are based on a common gaming and gamification methodology.

                                The Hologrammatic Corfu application was designed for the comprehensive exploration of the city before, during, and after the trip, leveraging transmedia content such as:

                              • photographs,
                              • 360° videos,
                              • augmented reality,
                              • hologrammatic videos.


                              • In addition, statistical analysis of point-of-interest visitation is used to enable dynamic visitor redirection, supporting sustainability, accessibility, and balanced tourist flow management.

                                The BRENDA application was designed to promote gastronomic and historical tourism, using serious gaming and gamification mechanisms that connect local businesses with cultural points of interest. This approach encourages active participation from both local communities and visitors, fostering sustainable and interactive tourism experiences.

                                Finally, the paper highlights the potential for reusing gaming mechanisms and transmedia elements in new areas of interest, contributing to the transformation of destinations into modern smart destinations.

                                  The development of Information and Communication Technologies (ICT), and in particular WebGIS tools, has significantly contributed to strengthening public participation processes, expanding the involvement of different stakeholder groups in urban planning and decision-making.

                                  The platform is technically based on open-source ppGIS solutions and integrates innovative online tools that support the key methodological stages of participatory design, using real spatial and urban planning challenges.

                                  The system enables:

                                • the creation of projects and sub-projects according to the stages of participatory urban design,
                                • the use of libraries of proposed solutions,
                                • the combination of user profiling and opinion weighting,
                                • the management and analysis of geospatial data through WebGIS tools.


                                • The main objective of the platform is to highlight key characteristics of public space and to organize processes for meaningful and equal citizen participation in urban planning.

                                  This research approach also aims to create an open community of users, experts, designers, and developers around an open-source ppWebGIS software, enhancing collaboration and participatory innovation in the fields of Smart Cities and urban planning.
