Sorter cannot help unimpaired teammates quickly (Blurry glasses)
Sorter cannot differentiate between items
Glasses make wearer more near-sighted
Items require sorting by specific shape, size, colour
Difficult to cooperate with teammates
("Big Man", or standing person helping others sort using our strategy)
Hard to notice where efficiency is lacking
Some teammates are not visible due to specific blur on glasses
Poor depth perception as items are at a distance
Cannot see progress of teammates
Cannot see number of sorted/unsorted parts
Sorter cannot move items around table effectively (Taped hands)
Sorter efficiency is limited (Non-dominant hand only)
Teammates are seated at different areas/distances around the table
Eyes focus on scratched/deformed areas instead of through the glasses
Cannot pick up items
Difficult to slide items on table
Cannot use fingers to pick up items
Cannot cup one hand/palm to hold items
Poor variability of area of contact with the table surface
Cluttered/busy table area
Taped hand acts as one flat body, limiting contact to fingertips (narrow) or hand parallel to table (wide)
Fingers are taped to palm of hands and prevent bending of fingers
Tape prevents bending of fingers and palm (horizontal and vertical axis are rigid)
Reach is limited
Limited sorting capabilities
Cannot "go around" other people grabbing items (one arm only)
Always bumping into people (given left hand is used due to non-dominant hand)
Sorter's body horizontally "leans into" reaches, blocking other people
Can only focus on one specific item
Sorter unfamiliar with non-dominant hand
One hand can hold limited amounts of objects
No other means of grabbing objects except for one hand
