Human Factors
Asked to hold at SHAFF intersection due to unexpected traffic saturation at EWR. While setting up FMC and consulting the arrival chart I expanded the view on my iPad to find any depicted hold along the airway at SHAFF intersection. In doing I inadvertently moved the actual hold depiction along the lower left hand corner of the chart out of view on the screen.The first officer and I only recall holding instructions that said to hold northeast of SHAFF; 10 mile legs.  I asked the first officer if he saw any depicted hold and he said no. We don't recall instructions to hold as depicted so not seeing a depicted hold along the airway at SHAFF we entered a right hand turn. I had intended to clarify the holding side with ATC however there was extreme radio congestion and we were very close to SHAFF so the hold was entered in a right hand turn. After completing our first 180 degree turn the controller informed us that the hold at SHAFF was left turns. We said that we would correct our holding side on the next turn. Before we got back to SHAFF for the next turn we were cleared to EWR.

Air carrier flight crew reported they entered the hold at SHAFF intersection on the FLOSI 3 Arrival to EWR with an incorrect turn due to the setup of their iPads.
