  8. Focus + Context Drawbacks • Front surface is usually removed or made less visible • Though it preserves context, spatial orientation might be lost image courtesy of Ivan Viola Peter Sikachev

  28. User Study Peter Sikachev

  29. User Study • Teaching video • Manual or dynamic f+c change • 2 tasks Peter Sikachev

  30. User Study • Teaching video • Manual or dynamic f+c change • 2 tasks on synthetic datasets • Find the number of spheres inside spheres Peter Sikachev

  31. User Study • Teaching video • Manual or dynamic f+c change • 2 tasks on synthetic datasets • Find the number of spheres inside spheres • Find the shortest distance between equicolored spheres Peter Sikachev

  32. User Study • Teaching video • Manual or dynamic f+c change • 2 tasks on synthetic datasets • Find the number of spheres inside spheres • Find the shortest distance between equicolored spheres • Questionnaire Peter Sikachev

  33. User Study: Results Proposed technique allows interact less with GUI to get the result Some users make fewer mistakes and complete tasks faster All users need more time to adjust Peter Sikachev
