The iPhone 6s will feature a 3D Touch Display, a revamped version of the pressure-sensitive screen and touchpad current used in the Apple Watch and new MacBook, according to reports.
The new screens will be able to differentiate between three modes; a tap, a press and a prolonged press as to their level of pressure - an advancement on the press/long press sensitivity of the Watch and Mac, according to 9to5Mac.
Force Touch is Apple's method of using a single surface to trigger multiple functions depending on how much pressure you apply. Force Touching an Apple Watch, for example, pulls up the menu to change the watch face, while Force clicking using a trackpad reveals locations when used on maps, previews a file's contents or adds an event to a calendar invite, and so on.
Force Touch's integration into the iPhone 6s could be used to trigger directions to a defined spot within Maps, or in-depth menu options within Apple Music.
Rumours have been circulating around the technology's use within the new iPhones for some time. It is also likely the new generation of iPads will benefit from it.
The iPhone 6s and 6s Plus are likely to benefit from a new 12MP camera, capable of shooting 4K video, with the front camera capable of recording 1080p video at 60fps, 240fps in slow motion mode and flash support.
The new phones are also expected to sport Force Touch technology, which detects how hard the user is pressing and allows different actions to be carried out accordingly. According to reports, the technology will allow menu "shortcuts" that enable users to find options on menus more quickly.
One of the most prevalent rumours is that the new generation of iPhones will see the introduction of a new rose-gold model.
Apple has sent out media invitations for a press event on Wednesday September 9, where chief executive Tim Cook is largely expected to introduce a revamped Apple TV box set alongside the new phones.
The new box is expected to feature a touch-pad remote, extra inbuilt storage and Siri voice control for browsing and selecting programmes and films to watch, in light of a recent patent filing.
The new box is expected to run a TV-optimised version of iOS 9 with a refreshed interface and, for the first time, may be opened up to the app community, with Apple expected to unveil a software development kit (SDK) that allows developers to build apps. At present, only a handful of third-party programs feature on the Apple TV and introducing an SDK and App Store would expand this significantly.
It will also support Homekit, after Apple confirmed that Apple TV would act as a central hub for its connected home appliances, including ecobee thermostats, lighting kits and smart sensors.
Apple is also expected to unveil a new larger 'iPad Pro', aimed at business users.
