Distant pointing at large displays allows rapid cursor movements, but can be problematic when high levels of precision are needed, due to natural hand tremor and tracking jitter. We present two ray-casting-based interaction techniques for large high-resolution displays – Absolute and Relative Mapping (ARM) Ray-casting and Zoom for Enhanced Large Display Acuity (ZELDA) – that address this precision problem. ZELDA enhances precision by providing a zoom window, which increases target sizes… CONTINUE READING
