I noticed what looked like new digital advertising boards at Tottenham Court Road going up the escalators - one continuous display. It seemed to be an advert for the advertising space itself. When I looked at it, standing on the right, it made me feel a bit dizzy/disorientated.
The digital boards are becoming more sophisticated and bright, and now moving images in one continuous display (so that the whole display is at an angle to line of sight) has the potential to make people feel a bit dizzy going up the escalator - not a good combination!
Maybe us humans are expected to multitask in this digital age, but I was ascending an escalator, not sitting in the front row of a cinema!
