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
