Data physicalization for climate change data using an interactive globe : exploration of encoding variables into leds

This thesis explores the potential of data physicalization for climate change data using an interactive spherical display. By integrating individually addressable LEDs, the project investigates the effectiveness of different encoding variables; colour and animation (blink speed) in enhancing data comprehension and user engagement. The study employs a combination of background research, system design, and user evaluation to assess the impact of these visual modalities on accuracy, mental load, satisfaction, and overall user experience. Results indicate that while animation modes yield higher accuracy in data interpretation, they also pose significant usability challenges. Blink speed, although accurate and engaging, was perceived as obtrusive and demanding. Colour-based representations were preferred for their ease of use and lower mental load. The findings underscore the importance of balancing visual effectiveness with user comfort in the design of spherical displays.
