The present disclosure involves an electronic device for visualizing a sensation experienced by a patient. The electronic device includes a touchscreen display configured to receive a tactile input from a user and display a visual output. The electronic device includes a memory storage component configured to store programming code. The electronic device includes a computer processor configured to execute the programming code to perform the following tasks: generating, in response to the tactile input from the user, a three-dimensional (3D) sensation map that represents the sensation experienced by the patient； deriving a two-dimensional (2D) sensation map based on the 3D sensation map, wherein the 2D sensation map contains substantially less data than the 3D sensation map； and sending the 2D sensation map over a network to facilitate a reconstruction of the 3D sensation map using the 2D sensation map.
