- This thesis explores the development of an intuitive gesture set for spherical displays, specifically within the context of astronomy education. Through a gesture elicitation study involving 30 adult participants, 16 referents were tested and analyzed, leading to the identification of a consensus set of gestures deemed natural, memorable, and easy to perform. The results show a strong agreement on basic navigational gestures such as rotating or zooming, and greater variability in more abstract actions like time control or undoing previous commands. The study also highlights how simple one-finger gestures tend to be perceived as more intuitive and effective. From a business perspective, the findings present valuable opportunities for companies seeking to innovate in customer engagement, digital communication, and immersive experience design. Spherical displays, when paired with natural and user-tested gestures, can enhance interactivity in sectors such as retail, events, museums, and corporate training. By relying on intuitive gestures, companies can reduce onboarding efforts, improve accessibility, and increase user satisfaction.
