New technology makes teacups and toy cars work as TV remote controls!Scientists have developed a technology that can turn everyday objects - such as teacups or toy cars - into remote controls for televisions.

Researchers said the ‘Matchpoint’ technology, which only requires a simple webcam, works by displaying moving targets that orbit a small circular widget in the corner of the TV screen.

These targets correspond to different functions - such as volume, changing channel or viewing a menu.

The user synchronises the direction of movement of the target, with their hand, head or an object, to achieve what researchers call ‘spontaneous spatial coupling’, which activates the desired function.

Unlike existing gesture control technology, the software does not look for a specific body part - such as a hand - it has been trained to identify.

The technology looks for rotating movement so it does not require calibration, or the software to have prior knowledge of objects.

This provides much more flexibility and ease for the user as it works even while hands are full.

When selecting volume adjustment or channel selection, sliders appear.

The user moves their hand, head, or object, in the required direction indicated by the slider to change the volume or to find the desired channel.

As well as televisions, the technology can also be used with other screens.

Multiple pointers can be created to allow more than one user to point at drawings or pictures on interactive whiteboards simultaneously.

Matchpoint also allows users to manipulate images on whiteboards by using two hands to zoom in and out, and rotate images.

In addition to short-term couplings, users can also link stationary objects to controls, which even when left for prolonged periods will retain their control function.
