BMW iDrive Touch Controller – fingertip control at its finest
The introduction of the BMW iDrive Touch sees the development team at the BMW Group integrating a touch-sensitive pad into the iDrive system’s central control unit, the iDrive Controller, for the very first time. Measuring 45 mm across, the multi-touch surface makes certain in-vehicle control functions more intuitive, faster and easier to use.
Incorporating the touchpad into the iDrive Controller means it is ergonomically positioned where it is easy to reach: with entry, selection and confirmation being performed in the usual way using the control knob’s rotate-and-press mechanism, the direct proximity to the touchpad means there is no need for any fumbling around.
The touch surface will initially be made available for the Chinese market from July 2012 and will add various convenience-enhancing functions to the iDrive Controller, including handwriting recognition as well as navigating in maps. One year later, availability of the iDrive Touch and these new functions will be extended to almost all other markets. At this point, a function for surfing the internet is also due to be added, which will allow the mouse pointer to be controlled in exactly the same way as on many handheld devices.
The handwriting recognition function enables characters to be entered with the finger by simply “writing” them on the surface of the touchpad. Whereas previously this could only be done with the “Speller” – a circular arrangement of letters in the display – by turning the control knob, the touch-sensitive surface now recognises the letters and the Speller instantly jumps to the right point of the alphabet. To further reduce driver distraction, a voice output repeats the character that has been recognised.
The handwriting recognition function is a tremendous boon for the Chinese market especially, which is why the BMW iDrive Touch Controller is making its debut there. With several thousand characters and as many as 21 strokes per character, entering text is a far more complex task than with the Latin alphabet. The reason the iDrive Touch Controller is of such great benefit in China is that the sequence of strokes for starting Chinese characters is basically set in stone, meaning that the selection of characters is already narrowed down considerably with the very first stroke entered by the driver. The choice is further refined with each additional stroke, allowing rapid selection of the relevant character.
Apart from recognising handwriting, the iDrive Touch also makes it possible to navigate freely within the route map shown in the display and zoom in on it, too. The scale is changed using the two-finger pinch gesture already familiar from many laptops und smartphones. If there is a traffic jam ahead, for example, the driver can adjust the scale of the displayed portion of map using the touchpad, move the view to the hold-up and take a look at the suggested alternative route.
The driver can also use touch control to mark the points of interest (POIs) stored in the map, then press the control knob to confirm his choice and display more detailed information. The later version of the iDrive Touch will furthermore allow the mouse pointer to be moved across the display while surfing the internet, just like on a home PC. Pressing the iDrive Controller will then have the same effect as clicking with the mouse.
