tvOS 9 shipped with several new features on the fourth-generation Apple TV. One major new feature was the ability to move through the interface with the new touchpad remote using multi-touch gestures. It also introduced a new App Store in which users can download and install new applications (such as apps and games) made available by developers for the Apple TV and tvOS. tvOS 9 adds support for Siri, which offers a multitude of features such as a cross-application search for a movie/TV show, rewind, fast forward, name and actor/director of the current movie, and skip back 15 seconds. tvOS added support for an application switcher on the Apple TV, more application customization options, cinematic screensavers, and control the TV using the included Siri Remote with the built-in support for HDMI-CEC in tvOS. In addition, tvOS allows the user to control the Apple TV in many different ways, such as using the included Siri Remote, pairing a third-party universal remote, pairing an MFi Gamepad to control games, using the Remote app on iOS, and pairing a Bluetooth keyboard to aid in the typing experience of the user.Accessibility
tvOS, derived from iOS, incorporates many of the accessibility features found in iOS and macOS. These include VoiceOver, Zoom, and Siri, which support users who are blind or have low vision. VoiceOver, a screen reader available in over 30 languages, provides spoken descriptions of on-screen content and supports navigation through gestures such as flicks, taps, and the rotor. The system includes options to increase screen contrast by reducing background transparency in various interface elements. A high-contrast cursor can be enabled to highlight focused content, and a Reduce Motion setting simplifies certain animations to minimize visual strain. tvOS supports audio descriptions for films, indicated by the AD (Audio Description) icon in the iTunes Store and in iTunes on macOS and Windows. Bluetooth keyboard support is also available. When used with VoiceOver, characters are read aloud as they are typed and confirmed. While designed for Apple’s keyboards, the system is compatible with most third-party Bluetooth keyboards. Closed captioning and SDH (Subtitles for the Deaf or Hard-of-Hearing) are supported for video content, with customizable caption styles and fonts. Compatible media is marked with CC or SDH icons in the iTunes Store. The Siri Remote allows for customization of the touch surface, including tracking speed adjustments and the option to disable the touch functionality entirely in second-generation or later models, using directional buttons instead. Apple’s Remote app for iOS devices can also control Apple TV. It includes support for Switch Control, which enables users with motor impairments to navigate the interface using compatible switch devices.Development
