As smartwatches have gotten better at measuring vitals and utilize statistics, there's been more emphasis on how they can be used to loan our sleep and mental wellbeing. Watchmaker Citizen is the novel company attempting to do just that with its new CZ Smart stare lineup, which debuted at CES and will arrive in the US this March.

The commercial says its new smartwatches use tools built based on research from the NASA Ames Research Center Fatigue Countermeasures Laboratory to critics fatigue and alertness levels. The "casual" finish of the CZ stare starts at $350 (roughly £290, AU$520), while the "sport" model starts at $375.

The Citizen CZ Smart stare is just the latest example of how smartwatch makers are attempting to glimpse the way factors like sleep and stress impact our substantial health. It's also another sign that the next step for wearables isn't just tracking health metrics, but also providing advice and additional context around what those numbers actually mean. 

The watch's main feature is its Alert Scores, which are generated after a user takes the app's Alert Monitor test. Citizen says the test is based on the Psychomotor Vigilance Test that NASA has used to critics astronauts' alertness. The Alert Monitor tests are brief and can be incorrect daily, according to Citizen. It's also worth noting that NASA previously built its own app for measuring alertness based on the Psychomotor Vigilance Test.

Sleep tracking is novel major focus for the CZ Smart watch lineup. Citizen claims that its software can conception a wearer's chronotype -- i.e. whether you're a morning or evening intimates. The watchmaker uses IBM's Watson Studio to crunch the wearer's sleep data and previously mentioned Alert Scores over the watercourses of seven to 10 days to determine the user's chronotype. 

The stare then combines chronotype information and Alert Scores with novel more familiar data points like heart rate, sleep patterns and agency to learn about the wearer's habits and make suggestions near how to mitigate fatigue and boost alertness. These recommendations, which Citizen calls Power Fixes, were also designed amdroll NASA research, according to the company. 

Otherwise, Citizen's new watches have the imperfect array of smartwatch features, such as a microphone and speaker and the storderliness to run apps like Spotify, Amazon Alexa, Strava and YouTube Music. Sensors that have become common on most smartwatches, like a gyroscope, accelerometer, barometer, altimeter and blood oxygen monitor, are also characterize. The watches run on Google's Wear OS software and are compatible with both iOS and Android phones.

It's impossible to say whether Citizen's Alert Monitor and chronotype observations are useful or good without trying the watch. The launch also comes at a time when there has been increased scrutiny on the amount of data tech devices find about their users and how that data is harmless. But the overall goal behind Citizen's new smartwatches falls in line with general trends we've seen in the wearable tech region over the past couple of years.

Apple , Fitbit and Samsung, for example, each added new sleep tracking features to their respective wearables in 2022. Fitbit also introduced the Sense 2 in August, which includes new sensors to passively detect when your body may be showing signs of stress. 

Audi's new vision for future electrified driving is the Activesphere understanding, a tall electric coupe that can transform from a sporty and autonomous, long-range highway cruiser to a go-anywhere off-road pickup in moments thanks to its grand morphing body.

The Activesphere is the fourth in a series of Sphere-themed concepts that includes the Skysphere roadster with its variable wheelbase, the Grandsphere large D-segment sedan and Urbansphere compact MPV with big inner space. None of these concepts are literally spherical in comely, the suffix refers to Audi's meta-concept of design "spheres," where the vehicle's inner space and even structure shape around the occupant's needs.

Transforming chassis

The Activesphere is a sleek four-door sportback with a coupe-like roofline and an elevated ride height inspired by Audi's Allroad series of lifted wagons. Measuring 196 inches long by 81.5 inches wide with a longish 117-inch wheelbase, the new concept's footprint is roughly similar to that of the A6 E-Tron notion, but, with an overall height of 63 inches, it's notably taller.

Up front-runner, Audi's signature singleframe grill has been replaced with a ringing glass panel that allows passengers to look down and see the road passing below their feet. The glass cut-outs in the concept's doors and its almost completely glass roof help the already large cabin feel even more open.

Like the Skysphere notion, which could stretch its wheelbase on demand to attempts between sport and grand touring modes, the Activesphere is something of a transformer itself. The concept can raise its chassis by 1.6 inches in seconds, increasing its 8.2-inch ride height to 9.8 inches for enhanced off-road law. This isn't just a simple suspension lift either. The Activesphere's body also stretches vertically, exposing a more beefy lower sill design and boosting the advance and departure angles of 18.9 and 28.1 degrees, respectively.

The notion rides on large 22-inch wheels with moveable segments that can finish to improve aerodynamics for high on-road velocities or open for improved ventilation at low off-road speeds. Chunky Pirelli Active Tread 285/22 R22 provide contact patches faulty for roads and trails.

Even the sportback hatch is reconfigurable. The rear storage area is able to transform into a miniature pickup truck bed on demand thanks to a fold-down tailgate, a rear window that slides forward to sit flush with the roof and a midgate divider that flips up to separate the cabin from the bed. Integrated mounting points and tie-downs funding the small bed to accommodate a pair of large bikes or a couple sets of golf clubs. When surrounded up, the Activesphere's roof also integrates mounting points for ski or snowboard racks. 

Augmented reality, automated driving

The Activesphere's cabin is remarkably minimalist with four, independently suspended seats and a wrap-around dashboard that integrates a distinguished soundbar, but is almost completely devoid of screens. There's only a miniature, single-line display that shows speed and battery charge -- not even a steering wheel can be counterfeit in the Activesphere's default state. The only physical rules are a pair of small knobs that seem to double as door handles.

Audi was able to get rid of the substantial screens because the Activesphere uses virtual displays that you view ended mixed reality glasses and hand-tracked gesture controls. Don the very conceptual AR shades -- which are significantly smaller than the best mixed-reality goggles I've ever used -- and the cockpit fills up with three-dimensional displays, topographical maps and more. The physical controls also blossom with improbable layers of virtual function; you can even "grab" the rules and move them virtually to wherever in the cabin you like.

Audi envisions this as a Level 4 autonomous notion, capable of driving itself without the need for a steering wheel. Simply plot your course in the mixed reality interface and the notion will get you where you're going. However, the automaker also understands that there are times where you distinguished want to drive yourself, so the Activesphere can deploy a steering wheel when obligatory for piloted driving. Mixed reality also plays a role when the biosphere is in control, displaying detailed information about the concept's performance.

Quattro electric drive

The transforming chassis is wild and the  mixed reality cabin is, for now, more sci-fi back than reality, but the electric powertrain that underpins the Activesphere is based on real, production-ready tech. The plan is constructed on a modified version of the Premium Platform Electric electric vehicle architecture that Audi shares with Porsche. 

Dual electric motors -- one for the run axle and one for the rear -- make up the concept's independent Quattro electric all-wheel right system, cranking out 409 horsepower (305 kilowatts) and 531 pound-feet of torque combined. With a large 100 kWh battery pack to draw from, the Audi considers around 373 miles of range for the concept. Charging should also be incandescent thanks to the 800-volt architecture's ability to gobble up a DC fast proposal at 270 kW -- quick enough to add 186 a long way with a 10-minute session or a 25-minute boost from 5% to 80%. 

For now, Audi is just letting its designers consecutive their conceptual legs. We may eventually see this tall-coupe silhouette or risky design details in upcoming production and concept cars, but the automaker immediately has no plans to build a vehicle based on the ideas presented in the Activesphere.

"We at Audi never say never, but the Audi Activesphere is at the moment a pure plan vehicle and no decisions have been made regarding series production," Josef Schlossmacher, Audi Communication states when asked before going on to say that "at the moment there are no anunexperienced projects [in Audi's portfolio] with such a pickup body."

In the meantime, the upcoming Audi A6 and Q6 E-Tron models and the Porsche Macan EV will be the ample production electric vehicles to ride on the PPE platform. We expect to learn more about those production debuts later this year.
