The EyeToy is a color webcam for use with the PlayStation 2. Supported games use computer vision and gesture recognition to process images taken by the EyeToy. This allows players to interact with the games using motion, color detection, and also sound, through its built-in microphone. It was released in 2003.

The camera was manufactured by Logitech, although newer EyeToys were manufactured by Namtai. The camera is mainly used for playing EyeToy games developed by Sony and other companies. It is not intended for use as a normal PC camera, although some programmers have written unofficial drivers for it.^[3] The EyeToy is compatible with the PlayStation 3 and can be used for video chatting.^[4] As of November 6, 2008, the EyeToy has sold 10.5 million units worldwide.^[5]

The EyeToy was conceived by Richard Marks in 1999, after witnessing a demonstration of the PlayStation 2 at the 1999 Game Developers Conference in San Jose, California.^[6] Marks' idea was to enable natural user interface and mixed reality video game applications using an inexpensive webcam, using the computational power of the PlayStation 2 to implement computer vision and gesture recognition technologies. He joined Sony Computer Entertainment America (SCEA) that year, and worked on the technology as Special Projects Manager for Research and Development.^[7][8]

Marks' work drew the attention of Phil Harrison, then Vice President of Third Party Relations and Research and Development at SCEA. Soon after being promoted to Senior Vice President of Product Development at Sony Computer Entertainment Europe (SCEE) in 2000, Harrison brought Marks to the division's headquarters in London to demonstrate the technology to a number of developers. At the demonstration, Marks was joined with Ron Festejo of Psygnosis^[8] (which would later merge to become London Studio) to begin developing a software title using the technology, which would later become EyeToy: Play. Originally called the iToy (short for "interactive toy") by the London branch, the webcam was later renamed to the EyeToy by Harrison. It was first demonstrated to the public at the PlayStation Experience event in August 2002 with four minigames.^[7]

Already planned for release in Europe, the EyeToy was picked by SCE's Japanese and American branches after the successful showing at the PlayStation Experience. In 2003, EyeToy was released in a bundle with EyeToy: Play: in Europe on July 4, and North America on November 4. By the end of the year, the EyeToy sold over 2 million units in Europe and 400,000 units in the United States.^[7] On February 11, 2004, the EyeToy was released in Japan.

The camera is mounted on a pivot, allowing for positioning. Focusing the camera is performed by rotating a ring around the lens. It comes with two LED lights on the front. A blue light turns on when the PS2 is on, indicating that it is ready to be used, while the red light flashes when there is insufficient light in the room. It also contains a built-in microphone.

The original logo and product design for the camera was designed by Sony employee Oliver Wright. A second, newer model of the EyeToy was also made, but sports a smaller size and silver casing.^[9] Apart from smaller electronics, no internal improvements had been made to the new model, and its functionality stayed the same as the old EyeToy.^[10]

Since the EyeToy is essentially a webcam inside a casing designed to match the PlayStation 2 and it uses a USB 1.1 protocol and USB plug, it is possible to make it work on other systems relatively easily. Drivers have been created to make it work with many computer operating systems, however, Linux^[11] is the only OS which has drivers installed yet no official drivers have been offered by Namtai, Logitech, or Sony for Microsoft Windows, macOS, or Linux. The type of driver required depends on the model of EyeToy camera. There are three different models:

• SLEH-00030
• SLEH-00031
• SCEH-0004

The model information is included in a label on the bottom of the camera.

In these custom drivers, the red LED that normally signals inadequate lighting is used as the active recording indicator. The blue LED is lit when the EyeToy is plugged into the computer.

EyeToy: Cameo is a system for allowing players to include their own images as avatars in other games. Games that support the feature include a head scanning program that can be used to generate a 3D model of the player's head. Once stored on a memory card, this file is then available in games that support the Cameo feature. EyeToy: Cameo licenses the head creation technology Digimask.
