Mean scores in survey responses, grouped by grasping force results

Question	Mean Score (± Standard Deviation)
Question	No Effect (n = 5)	One Hand (n = 5)	Both Hands (n = 9)
Tactile Feedback helped me perform the task	3.60 (±0.55)	3.80 (±0.84)	4.00 (±0.71)
Tactile feedback had no effect on my performance	2.80 (±0.84)	2.40 (±1.52)	2.11 (±0.78)
With tactile feedback, I grasped tissue with less force	3.60 (±0.55)	4.20 (±0.84)	4.33 (±0.87)
The balloon inflations were easy to feel	4.00 (±1.22)	4.60 (±0.55)	4.44 (±0.53)
I found myself ignoring the balloon inflations	2.40 (±1.14)	1.60 (±0.55)	1.67 (±0.50)
The balloon inflations were intuitive	3.20 (±0.84)	4.40 (±0.89)	3.78 (±0.44)
The inflations became more difficult to feel over time	2.60 (±0.89)	2.00 (±0.71)	1.67 (±0.50)
Avoiding drops was my highest priority	2.80 (±1.10)	3.40 (±1.14)	2.56 (±0.88)
Delicate grasping was my highest priority	3.20 (±0.84)	3.40 (±0.89)	3.78 (±0.83)
