Modern-day cars now have more than 100 electronic parts, from electric windows and heated seats to all-singing, all-dancing entertainment systems.

This may make driving easier for car owners, but as motors become more complicated, the skills required to fix them become more advanced.

To tackle this, BMW has designed a pair of augmented reality glasses that show users step-by-step instructions on how to fix an engine, simply by looking at it – and you don’t need previous mechanical experience to use them.

This is because animations shown via the glasses explain exactly how to disassemble car parts, and even which direction to turn a screw, for example.

The glasses are part of BMW’s wider augmented reality project. The software includes various BMW makes and models and can be updated for newer models.

When a mechanic looks at the engine of a BMW, while wearing the glasses, a three-dimensional colourful display is laid over the top of the original engine view.

The glasses are used to diagnose where the fault is and will take the wearer through step-by-step instructions to fix it. At each point, the relevant engine part is highlighted and an instruction is displayed in the top left-hand corner of the screen.

The glasses even show a picture of the tool needed for the job and come with headphones to talk you through the procedure. – Daily Mail
