Historically, the study of New Technologies has seen the evolution of the various disciplines involved in technology evaluation, in terms of safety, usability, and the overall experience (from ergonomics to User Experience, and cyberpsychology). These disciplines have identified the "user needs" as the fundamental guideline for evaluation and design. However, a theoretical contextualization of the concept of user needs is still missing. This dissertation proposes a theoretical model (PIM) based on the relationship between technology and user intentions. Based on the psychological and philosophical literature, it defines intentions as the hierarchically-structured mental antecedents of actions. Starting from the model, three experiments are presented focusing on the interaction with the technologies and motor, proximal and distal intentions. The results of the first experiment indicate that the use of interactive technologies can modify the representational content of motor intentions. The second experiment shows that the presence of proximal intentions in users drives their perception of affordances in the technologies and their final evaluation. The third experiment shows that users’ distal intentions influence the evaluation of usability in the technology and the experience of usage-related emotions. The conclusion explores the importance of intention analysis in technology evaluation.
Storicamente, lo studio delle Nuove Tecnologie ha visto l’evoluzione di diverse discipline interessate alla valutazione delle stesse, in termini di sicurezza, usabilità, esperienza globale (dall’Ergonomia fino alla User Experience, passando per la cyberpsicologia). Tali discipline hanno identificato nei “bisogni degli utenti” la guida fondamentale di valutazione e design. Tuttavia, è mancata una contestualizzazione teorica del concetto di bisogno dell’utente. A tal proposito, questa tesi propone un modello teorico (PIM) basato sulla relazione tra tecnologie e intenzioni degli utenti. Queste ultime, sulla base della letteratura psicologica e filosofica, sono viste come l’antecedente mentale delle azioni, strutturate gerarchicamente. Sulla base del modello, vengono presentati tre esperimenti incentrati sull’interazione con le tecnologie e le intenzioni al livello motorio, prossimale e distale. I risultati del primo esperimento indicano che l’utilizzo di tecnologie interattive può modificare il contenuto rappresentazionale delle intenzioni motorie. Il secondo esperimento mostra che la presenza di intenzioni prossimali in utenti orienta la loro percezione di opportunità d’azione e la valutazione della tecnologia. Il terzo esperimento dimostra che la presenza di intenzioni distali negli utenti influenza la valutazione di usabilità di una tecnologia e le emozioni ad essa legate. La conclusione della tesi approfondisce l’importanza dell’analisi delle intenzioni nella valutazione delle tecnologie.

Abstract
Historically, the study of New Technologies has seen the evolution of the various disciplines involved in technology evaluation, in terms of safety, usability, and the overall experience (from ergonomics to User Experience, and cyberpsychology). These disciplines have identified the "user needs" as the fundamental guideline for evaluation and design. However, a theoretical contextualization of the concept of user needs is still missing. This dissertation proposes a theoretical model (PIM) based on the relationship between technology and user intentions. Based on the psychological and philosophical literature, it defines intentions as the hierarchically-structured mental antecedents of actions. Starting from the model, three experiments are presented focusing on the interaction with the technologies and motor, proximal and distal intentions. The results of the first experiment indicate that the use of interactive technologies can modify the representational content of motor intentions. The second experiment shows that the presence of proximal intentions in users drives their perception of affordances in the technologies and their final evaluation. The third experiment shows that users’ distal intentions influence the evaluation of usability in the technology and the experience of usage-related emotions. The conclusion explores the importance of intention analysis in technology evaluation.File | Dimensione | Formato | |
