Left Side (Directional Pad/Joystick)

The left should include a directional pad or joystick to use in pointing or directional manipulation.

In order of preference we should include:

1. A circular "rocker" on top of four contacts but made of a single piece of plastic that allows for easy 8-way directional pointing.

2. In the interests of space, the 4-way directional pad could be replaced with a short joystick. We'd like to avoid the clunkiness and fragility of most cellphone joysticks. A good example of a gaming joystick would be in either the GP2X, the GP32 (an earlier version of the GP2X) or the controller on the NeoGeo. For examples, see the first three examples in the photos section below.

3. A Sony Playstation-like 4-way directional-pad with single piece of plastic but exposed or shaped into 4 roughly distinct buttons and shaped to allow pointing in diagonals (see the Playstation controller or Nintendo controller for examples).

Right Side (Buttons)

Since there is additional room on the right side, we should take advantage of this and include 4 buttons. The ideal layout would be in a diamond shape so it could be used a more traditional four-way directional pad if necessary.

If two buttons are used instead of three, they should be distinct buttons and placed an angle from each other with the right button above the left. A third extra button offset either above or below would be useful.

We do not recommend using a 4 directional rocker "dpad" on the right hand side. There are several reasons for this. First, because there is a well-established convention to lay out separate buttons on the right hand side, as evidenced by numerous controller illustrations below. Second, naming the controls becomes difficult. For example, instructing someone to "press down" becomes ambiguous - did you mean down on the left rocker, or down on the right rocker? Third, many games utilize multiple button combinations on the right hand side wich are difficult..
