One can easily convert almost any soft object into a touch − input device that can detect both touch position and surface displacement by embedding multip 且 e FuwaFuwa sensor modu 且 es in the object . A variety of example app 且 ications mustrate the utility of the FuwaFuwa sensor modu 且 e 。 An eyaluation of the proposed deformation measurement technique confirms its effectiveness
