Jaguar Land Rover and Cambridge have developed a touchless touchscreen

Jaguar Land Rover and the University of Cambridge are working on new touchscreen technology that eliminates the need to touch the screen. Counterintuitive, right? It’s called “predictive touch” for now, in part because the system is able to predict what you might be aiming for on the screen.  The video at the top of this post is the best way to understand how users will interact with the tech, but weÂ’ll do some more explaining here. You simply reach out with your finger pointing toward the item on screen that you want to select. ItÂ’ll highlight the item and then select it. HereÂ’s how it works, according to the University of Cambridge: “The technology uses machine intelligence to determine the item the user intends to select on the screen early in the pointing task, speeding up the interaction. It uses a gesture tracker, including vision-based or radio frequency-based sensors, which are increasingly common in consumer electronics; contextual information such as user profile, interface design, environmental conditions; and data available from other sensors, such as an eye-gaze tracker, to infer the userÂ’s intent in real time.” Cambridge claims that lab tests showed a 50 percent reduction in both effort and time by the driver in using the screen, which would theoretically translate to more time looking at the road and less time jabbing away at the screen. If the prediction and machine learning tech is good enough, we could see this resulting in a reduced number of accidental inputs. However, on a certain level it almost sounds more difficult to point at a screen while moving than it does to actually touch a section of that screen. Without using the tech and its supposedly great predictive abilities, we canÂ’t come to any grand conclusions. One comparison you may already be thinking of is BMWÂ’s Gesture Controls. ItÂ’s already been addressed with a subtle diss from Cambridge: “Our technology has numerous advantages over more basic mid-air interaction techniques or conventional gesture recognition, because it supports intuitive interactions with legacy interface designs and doesnÂ’t require any learning on the part of the user,” said Dr Bashar Ahmad of the University of Cambridge. Of course, this tech can be used for much more than just vehicle touchscreen control. Cambridge says it could be integrated into ATMs, airport check-in kiosks, grocery store self checkouts and more.

Buy a Jaguar E-Type continuation, get a matching wristwatch

From time to time, automakers release special branded watches. Jaguar and Land Rover are no different. The latest from Land Rover isn't particularly remarkable, but one new Jaguar piece is pretty special. Jaguar partnered with British watchmaker Bremont for a line of watches, the most impressive being a 43mm watch that commemorates Jaguar's continuation series of Lightweight E-Types. Like the cars, only six of the watches will be produced, and they will be offered to the owners of those $1.5 million cars. Each watch features a serial number that matches a corresponding car, and the faces have been designed to look like the instruments aboard the E-Types. The same goes for the hands, which look like the gauge needles. The winding crown also has a tire tread pattern that wraps around the sides, with Jaguar's heritage logo on the top. And these timepieces are built with aluminum left over from the continuation E-Types. On the back is the most impressive part, though. Here is where the watch's automatic winding weight is visible. It's shaped like a vintage steering wheel, and the outer rim is made from real wood. The weight keeps the watch and its exclusive Bremont movement wound. If you can't afford this ultra-limited watch, Bremont has a line of other Jaguar watches with many of the same design cues, at prices ranging from less than $5,000 to more than $11,000. The Land Rover watch is a bit disappointing, since it bears little apparent connection to the vehicles. Zenith, the Swiss company that partnered with Land Rover for the piece, claims the design is inspired by the Range Rover. And Land Rover claims a connection in that a British explorer wore the same series watch while completing an expedition with a pair of Range Rovers. There's also the fact that the watch and the SUV are both made of aluminum, but otherwise, the Zenith watch doesn't look particularly automotive. The box sounds pretty cool, though, since it's fashioned from Land Rover wood and upholstery. Related Video:

Top horsepower-per-dollar cars in 2017

Bang for the buck. That quasi-scientific statistic is bandied about by motor heads everywhere from classrooms to barrooms, though the truth of the matter is that it's exceedingly complex to measure. A fair performance-per-dollar index would include something like cross-referencing MSRP (Manufacturers Suggested Retail Price) with point-to-point times on a track or driving route, which is obviously hard to do comprehensively. But, for the sheer joy of talking about cars and playing with a big spreadsheet, there's always the horsepower-per-dollar index, which is more straightforward, albeit hilariously flawed. There are vagaries even with this simple formula, of course: MSRP for vehicles can change at a moment's notice, to say nothing of the bottom-line shifting that happens with local deals or showroom negotiation. For this list we're running with the straight MSRP wherever possible, and as recently reported as we can get it. All the vehicles on this list are 2017 models, and all trims are reported where the lowest price and differing power levels intersect. Some choices were made for personal preference and some for sanity, avoiding things like all 48 trim levels of the Ford Transit, all with the same horsepower). If this list were a simple top ten, or even a top fifty, you'd be bored to tears with all the red, white and blue that is represented. Following perfectly with conventional wisdom, American cars really do lead the world where hp/$ is concerned. So, for the sake of variety (and the sheer joy of seeing a minivan 'win' one round of this thing) I've sorted out some top five and bottom five lists for broad power categories. Let's dive in. Less Than 100 Horsepower Okay, okay, this is hardly a category we'll grant you. But we've often tried to click off all the sub-100-hp cars on sale in the US, and making this list gave us an excuse. It also illustrates that none of these smallish vehicles bring cheap horsepower to the table - for that you'll need a motorcycle. The segment-leading Chevy Spark (above) asks just over $139 for each hp, and that Smart Fortwo Electric Drive has hp on sale for about the same price as its very distant family cousin, the Mercedes-Benz SL65 AMG (insert your favorite Smart joke here... we know you want to).
