Project Details

ELMO is an optical see-through head-mounted display (HMD) capable of showing opaque virtual objects interacting with real objects. Occlusion is achieved by using a secondary LCD to properly block incoming light on a pixel-by-pixel basis.  
 
"ELMO realizes a 3D collaborative workstation that has the following three advantages:" 
 
1 - unlike video see-through HMDs, users can see non-digitized real collaborators for superior awareness and natural non-verbal communication cues 
 
2 - unlike fixed displays, virtual objects can appear anywhere in the workspace, e.g., between to user's faces 
 
3 - unlike conventional optical see-through HMDs, virtual objects can be transparent or opaque as required by a certain task
