This study investigates how people interact with large-scale information visualization (InfoVis) using touchless methods. InfoVis involves displaying complex data in visual forms, such as graphs or charts, to help people understand and analyze information. This study specifically looks at how virtual guidance from the user interface affects the user experience when interacting without touch.

Participants in this study will engage with InfoVis systems using touchless technology, which means they will not need to physically touch the display. The study will observe how virtual guidance, which provides on-screen instructions or cues, impacts their ability to navigate and understand the visual information.

• Who can participate: The eligibility criteria for this study are not specified, but typically participants should be above a certain age and capable of using touchless technology.
• Study details: Participants will use touchless technology to interact with visual data displays. They will receive virtual guidance, which includes on-screen instructions, to help them navigate the system.
