For performance drivers, imagery that could aid track driving by offering an enhanced ‘virtual’ view of the road or race track.
The ‘Jaguar Virtual Windscreen’ concept uses the entire windshield as a display so the driver’s eyes need never leave the road. High quality hazard, speed and navigation icons could all be projected onto the screen together.
Dr Wolfgang Epple, Director of Research and Technology for Jaguar Land Rover said: “We are working on research projects that will give the driver better information to enhance the driving experience. By presenting the highest quality imagery possible, a driver need only look at a display once. Showing virtual images that allow the driver to accurately judge speed and distance will enable better decision-making and offer real benefits for every day driving on the road, or the track.”
JLR is developing a gesture control system to keep the driver’s eyes on the road and reduce distraction by limiting the need to look at or feel for buttons and switches to press. [infobox color=”light grey”]
- Racing line and braking guidance. Virtual racing lines on the windscreen appear to be marked on the track ahead for optimum racing line, with changes in color to indicate braking guidance.
- Ghost car racing. Improve your lap times by racing a ‘ghost car’ visualization of your car on a previous lap, or compete against a lap uploaded from another driver.
- Virtual cones can be laid out on the track ahead for driver training. These could be moved as the driver’s ability improves.
E-Field Sensing that Jaguar has developed is based on the latest capacitive discharge touch screens and gives much greater accuracy than ever before. A smartphone today detects the proximity of a user’s finger from 5mm (.196 inches). The system increases the range of the sensing field to around 15cm (5.9 inches) which means the system can be used to accurately track a user’s hand and any gestures it makes inside the car.
“Gesture control has already become an accepted form of controlling anything from TV sets to games consoles. The next logical step is to control selected in-car features. We have identified which functions still need to be controlled by physical buttons and which could be controlled by gesture and carefully calibrated motion sensors,” said Dr Epple. “The system is currently being tested on a number of features including sunblinds, rear wipers and satellite navigation maps. It has the potential to be on sale within the next few years.”
Jaguar says it is looking at technology that could replace rear view and external mirrors with cameras and virtual displays. Using two-dimensional imaging to replace mirrors is limited by the fact that single plane images on a screen do not allow the driver to accurately judge the distance or speed of other road users.
The innovative 3D instrument cluster uses the latest head and eye-tracking technology to create a natural-looking, specs-free 3D image on the instrument panel. Cameras positioned in the instrument binnacle or steering column area track the position of the user’s head and eyes. Software then adjusts the image projection in order to create a 3D effect by feeding each eye two slightly differing angles of a particular image. This creates the perception of depth which allows the driver to judge distance.
