In 2D/2.5D Data exploration, this work exploits and extends the concept of data annotations to provide guidance in discovering interesting areas while navigating with the lens suggesting annotations and displaying them without introducing clutter.
Challenge 🫥
Challenge 🫥
Exploration using lenses requires users; to continuously switch between complex-gesture-combinations; for selecting areas of interest by moving the camera and controlling, scaling and positioning lenses to perform inspection. Maintaining an effective focus-and-context visualization is difficult. Switching user-interface and mental modes increases cognitive load.
Solution 🎯
Solution 🎯
With our approach, we support a self-paced exploration of annotated models, directing users towards interesting areas and displaying annotations one at a time without introducing clutter or confusion.
Interesting Annotations were designed by referring to existing literature and domain experts
