![]() However, to ensure that all players can enjoy the game, it's best to always provide alternative input options that a player can configure or choose to use. It's OK to have the primary interaction method for components in your game be through a mouse, an analog input, or any other mechanisms of your choice. Similarly, when menu UIs are strictly navigable through mouse or analog thumb stick input alone, a player who can only access single-press digital buttons might be unable to configure their settings or begin their game altogether. In these examples, players who can't meet the physical demands of quick, repetitive button presses or holding down buttons for longer periods of time are excluded from progressing through any points in the game beyond a boss battle or a closed door. For example, a player might be required to repeatedly mash two buttons to beat an in-game boss, or hold down the right trigger for 3 seconds to open a door. It's important to evaluate the type of input needed as well as the specific timing or speed needed to activate those inputs to play the game. Players who have hand tremors might also find using a mouse very difficult and might prefer a keyboard instead. They might have trouble tracking a pointer or cursor on the screen. This exclusion affects players who are blind and can't use devices (like a mouse) that require hand-eye coordination and players who have low vision. Players can be excluded from a game experience by the input mechanism requirements that a game has for example, a PC game that can only be played with a mouse and doesn't support keyboard input. It's common for controller form factors as well as control schemes to often make assumptions about physical abilities without taking into account how diverse the player community is. Games often require the use of a wide array of input mechanisms like a mouse, analog inputs such as thumb sticks or triggers, the use of single-press digital inputs (like controller buttons or keyboards), voice or sound input, and many others. The change in the position and arrangements of these blobs are interpreted as mouse cursor movement and mouse clicks.The goal of this Xbox Accessibility Guideline (XAG) is to ensure that a player can operate the gaming interface through input mechanisms of their choice. ![]() ![]() The IR camera detects those bright IR blobs using computer vision. The user cups their hand, as if a physical mouse was present underneath, and the laser beam lights up the hand which is in contact with the surface. The laser beam module is modified with a line cap and placed such that it creates a plane of IR laser just above the surface the computer sits on. Both IR laser and IR camera are embedded in the computer. ![]() Mouseless consists of an Infrared (IR) laser beam and an Infrared camera. Mouseless removes the requirement of having a physical mouse altogether, but still provides the intuitive interaction of a physical mouse with which users are familiar. Despite the advances in computing hardware technologies, the two-button computer mouse has remained the predominant means to interact with a computer. Mouseless is an invisible computer mouse that provides the familiarity of interaction of a physical mouse without actually needing a real hardware mouse. ![]()
