Situation: Introduction of Automated Inspection Systems
• Currently:– Product flows along shackle line– Inspectors, workers communicate directly
• One inspector per trimmer
– Leverage gesture, speech• Develop efficient shorthand
• Inspection technologies being introduced– Trim tasks not yet automated
New Problem: Communication between Systems and Trimmers
• Automated systems need to communicate information about product on lines– No direct human communication
• How to display information to trimmer?
• How to associate tasks with specific birds?
Investigated Various Possibilities
• Solution must– Keep workers hands free– Not require technology near line
• Looked at wearable auditory and visual displays– Problem: relating tasks to specific bird
Solution: Augmented Reality
• Directly merge graphical display with worker’s view of world
• Task info spatially aligned with relevant product
Example Symbolic Instructions
See-through Head-Worn Display
• Monocular, transparent display
• Very little visual obstruction
Laser Scanner
Comparison
• Wearable Heads-up Display– No active technology installed in factory
• Potential for wide area use
– Display anywhere, esp. on product– Fragile, potentially encumbering
• Laser Scanner– Hardened, permanent install done once– Difficult to display on product– Nothing carried by worker
Experimental Evaluation Planned for Coming Year
• Compare human, HMD, Laser
• Use synthetic, similarly demanding “task”
