The hand from above

In the latest installation by Chris O’Shea, “unsuspecting pedestrians will be tickled, stretched, flicked or removed entirely in real-time by a giant deity”

Using the BBC’s Big Screens, which are installed in various UK city centres, the Hand From Above playfully transforms passers-by

“The BBC Big Screen is fitted with a CCTV camera, linked into a computer that runs the software then outputs to the screen,” explains O’Shea. “The software picks a person based on their proportions and how apart they are from other people, then tracks the blob over time using optical flow. If the giant hand removes, flicks or shrinks a person, firstly it rubs out the person from the live video using the background reference pixels. Then the tracked person is redrawn over the top in relation to what the hand is doing, ie being picked up, or flying out to the left of the screen (not shown in this video). When the hand shrinks a person it redraws them into the video at half scale. When there is too big a crowd it resorts to tickling people, with a random selection.”

Hand from Above is a joint co-commission between FACT: Foundation for Art & Creative Technology and Liverpool City Council for BBC Big Screen Liverpool and the Live Sites Network. It premiered during the inaugural Abandon Normal Devices Festival from September 23 to 27. It will next be on show at the BBC Big Screen in Cardiff from October 22 to 24.
