Image data generation using a handheld electronic device

The present disclosure provides improved generation of image data using a handheld electronic device 102. Motion of the handheld electronic device 102, with respect to a surface 108, is detected using a sensor 110 of the handheld electronic device 102 and data, dependent upon the sensed motion, is transmitted from the device to a remote electronic device over a wireless communication channel 114. An image 120, dependent on the transmitted data, is rendered on a display 118 of the remote electronic device 104 in response to the transmitted data and provides a user with visual feedback of the motion of the handheld electronic device 102. The image data may be generated by the handheld electronic device 102 or by the remote electronic device 104.
