“The shape of the Substitute Phone replicates an average smartphone, however, its functions are reduced to the movements we make hundreds of times on a daily basis. The stone beads which are incorporated in the body let you scroll, zoom and swipe. there are no digital functions. Thee object, which some of us describe as a prosthesis, is reduced to nothing but the motions. This calming limitation offers help for smartphone addicts to cope with withdrawal symptoms. The object as a therapeutic approach.”
