Abstract: An ergonomic grip for a portable game console comprising a central body portion with a left handgrip and a right handgrip connected to the left and right sides of the central body portion. A central recessed area is formed between the left handgrip and the right handgrip. Cushioning tabs are positioned at one or more interior surfaces of the ergonomic grip facing the central recessed area. The tabs are compressible to both cushion a portable game console positioned in the central recessed area and retain the portable game console via friction fit. The cushioning tabs are adapted to be compressed between the portable game console and the corresponding interior surfaces. The degree of compression of the tabs is variable with the size of the portable game console so that portable game consoles of different sizes will be securely held within the central recessed area.

Abstract: Systems and methods for alleviating problems encountered when using a conventional thumbstick by augmenting the thumbstick to enable swiveling (rotational movement) around the center or z axis of the thumbstick. In one embodiment, the swiveling motion is achieved by providing a swivel top mounted in a base that can itself be mounted on a post or a conventional thumbstick. In this embodiment, a rigid table having a split shaft and barbed retention clip is inserted into a receiving or retention hole in a connector base. A bearing surface and bearing raceway are provided to maintain the stability of the table while allowing it to rotate with respect to the base. The base may have legs that are configured to clip onto the top of a conventional thumbstick, or it may be configured to be mounted on a post of a three-axis potentiometer.
