Lanza Cruz, Indira Lázara
This thesis delves into a novel research area in Social Business Intelligence (SBI) focusing on social indicators. It proposes advanced methodologies for discovering and describing social indicators, using social network metrics and dynamic contexts. The main contribution is the proposal of a comprehensive methodological framework for the development of SBI projects, addressing the necessity for a semantic infrastructure. The framework abstracts various methodological processes that can be adapted and extended to suit diverse analysis tasks. The implementation of an author profiling method based on multidimensional business perspectives allows the identification of business roles within user profiles on social media. This finding introduces a novel quality indicator for assessing content reliability. Finally, the feasibility of developing quality indicators semi-automatically to identify relevant content is demonstrated. In summary, the proposed infrastructure enables the extraction of valuable insights for organizations seeking to measure the impact of their actions in social media.

Gomez-Cambronero, Águeda
Depression is the most prevalent mental disorder in our society, leading to disability and suicide deaths. Although effective evidence-based psychological treatments exist, they reach only a fraction of those in need. Smartphone-based interventions offer one possible solution to expand access, though challenges such as high dropout rates need to be addressed. This dissertation introduces "Horizon: Resilience", a smartphone-based Serious Game intervention for depressive symptoms. In this city builder game, players manage a town with the goal of progress and psychological resilience for its inhabitants. It integrates Cognitive Behavioral Therapy and Positive Psychology techniques, incorporating physical activity through motion sensors. The game was qualitatively and quantitatively evaluated by psychologists and patients, and a protocol for a future pilot RCT study towards efficacy and usability was designed. This thesis resides on the crossroads of Computer Science and Psychology, combining state-of-the-art techniques of both to come to a novel psychological treatment delivery.

Szczurek, Krzysztof Adam
This thesis addresses the need for reliable and immersive human-robot interfaces in hazardous environments. Three key goals were achieved. Firstly, techniques were developed to provide immersive interactions while ensuring accurate robot positioning in a realistic underground particle accelerator environment. A network optimization framework facilitated using Mixed Reality (MR) technologies for collision detection, trajectory planning, and real-time control. Secondly, an Augmented Reality (AR) interface was designed for wireless network environments, enabling efficient interaction through hand and eye tracking, motion tracking, and voice recognition. The interface allowed collaboration among multiple experts in the AR workspace. The interface's performance was evaluated in real intervention scenarios at CERN, meeting operational requirements. A comparison with a 2D interface was conducted, assessing safety and efficiency using various assessment methods and physiological measurements. The developed MR human-robot interfaces demonstrated operational readiness. Limitations and areas for improvement were identified, including optimizing network architecture and applying automatic interaction strategies.

Today a large percentage of the population suffers from anxiety-related problems. This anxiety can appear in day-to-day situations. An effective therapy for these problems is exposure. In it, the person is gradually exposed to what he fears. However, these therapy sessions are long and force the patient and therapist to travel to a specific place. Here, the use of a mobile application that guides the patient during the exposure sessions can be beneficial. Until now, this application did not exist, due to the complexity of its implementation. In this doctoral thesis, the necessary tools have been implemented to facilitate the implementation of this type of solution. In addition, in collaboration with psychology professionals, a mobile application has been implemented to self-guide exposure, which has been positively assessed by an external committee of experts.
