Abstract: An ergonomic case for a smartphone features contoured finger grips at appropriate locations around the outside surface, in a pattern that provides a comfortable and ergonomic grip for a hand. Specifically, three or four finger indentations are provided in the position of use in voice calling mode. The finger indentations may be located on either side, depending on whether the particular embodiment is intended for right or left-handed users. An additional thumb indentation may optionally be provided on the opposite side. The finger indentations and thumb indentations are used to hold the smartphone, to provide a more comfortable and secure grip for the fingers, and may include ridges or another high-friction surface in the indentations.
