A computer-implemented method, comprising: applying, by a first transducer that is mechanically coupled to a first portion of a display screen of a mobile computing device, a first force that causes a first movement of the first portion of the display screen; detecting, by a second transducer that is mechanically coupled to a second portion of the display screen, movement of the second portion of the display screen, the second portion of the display screen being different than the first portion of the display screen; determining a relationship between the first movement caused at the first portion of the display screen by the first transducer and the movement detected at the second portion of the display screen by the second transducer, wherein determining the relationship between the first movement and the movement detected at the second portion of the display screen comprises determining a transfer function that describes a transfer of movement from the first portion of the display screen to the second portion of the display screen; and applying, by the first transducer, a second force that causes a second movement of the first portion of the display screen, the second force being determined by a computing system of the mobile computing device using the determined relationship between the first movement caused at the first portion of the display screen by the first transducer and the movement detected at the second portion of the display screen by the second transducer, comprising obtaining a reference transfer function that describes a transfer of movement from a first portion of a reference display screen to a second portion of the reference display screen; determining a compensation function that compensates for a difference between the transfer function and the reference transfer function; and applying the second force based at least on the compensation function. applying, by a first transducer that is mechanically coupled to a first portion of a display screen of a mobile computing device, a first force that causes a first movement of the first portion of the display screen; detecting, by a second transducer that is mechanically coupled to a second portion of the display screen, movement of the second portion of the display screen, the second portion of the display screen being different than the first portion of the display screen; determining a relationship between the first movement caused at the first portion of the display screen by the first transducer and the movement detected at the second portion of the display screen by the second transducer, wherein determining the relationship between the first movement and the movement detected at the second portion of the display screen comprises determining a transfer function that describes a transfer of movement from the first portion of the display screen to the second portion of the display screen; and applying, by the first transducer, a second force that causes a second movement of the first portion of the display screen, the second force being determined by a computing system of the mobile computing device using the determined relationship between the first movement caused at the first portion of the display screen by the first transducer and the movement detected at the second portion of the display screen by the second transducer, comprising obtaining a reference transfer function that describes a transfer of movement from a first portion of a reference display screen to a second portion of the reference display screen; determining a compensation function that compensates for a difference between the transfer function and the reference transfer function; and applying the second force based at least on the compensation function.
