Goodyear Unveils the Future of Tyres, With Spherical, Maglev Wheels //hadiges inshort 360 degree wheels

Yep, your new tyre is basically a rubberised BB-8.

With self-driving vehicles inching ever closer to reality, there are more than a few autonomous vehicle designs floating around. But we've never seen one quite like this.

Tyre giant Goodyear has shown off an ambitious wheel concept that offers a glimpse of what driving in the near future might look like. Doing away with the conventional wheel and axle setup, Goodyear envisages cars being carried by four spherical tyres, which can swivel their tread in 360 degrees to help the vehicle move in ways that today's cars never could.


Dubbed 'Eagle–360', the company says these multi-orientation tyres would provide superior manoeuvrability to today's mechanically aligned wheels, letting each tyre independently respond to potential hazards, such as ice on the road or sudden obstacles.


In theory, they could also provide a smoother ride, enabling the car to move sideways in instances like overtaking or lane changes, without requiring the nose of the vehicle to turn. Check out the video above and you'll get an idea of how that could work.


Goodyear says sensors in the tyre could monitor road and weather conditions – and communicate this to other nearby vehicles – in addition to keeping an eye on the quality of the rubber tread. With the tyres in theory being 3D-printed, Eagle–360 could be customised to the terrain that you usually drive in.


One of the most impressive features is the way these spherical tyres could help cars navigate in cramped spaces. Rather than being required to undergo a series of three-part-turns and back-and-forth shimmying to get into a tight parking space, spherical wheels that can move in any direction could let you just glide into any available spot without changing the orientation of the vehicle.


Provided the car can actually fit in a free spot, you wouldn't have to worry about any other geometry – although that might not be a problem in the cities of tomorrow anyhow.


That's all well and good, but how would it actually work? While Goodyear acknowledges that Eagle–360 is just a concept, and not a real product it's actually working on, the company says tyres like this would use magnetic levitation to do their thing.


In other words, the wheels wouldn't be mechanically connected to the rest of the vehicle, but instead the body of the car would be suspended above its wheels by magnetic force.


It sounds pretty sci-fi, but the same principle applies in maglev trains and hoverboards, so it could be doable for cars in the future too. We don't expect to see Eagle–360 rolling us around the  neighbourhood any time soon, but it's an awesome idea that could make sense someday.

Tangible User Interface

By
Tangible User Interface (TUI) Imagine having a computer system that fuses the physical environment with the digital realm to enable the recognition of real world objects . In Microsoft Pixelsense (formerly known as Surface), the interactive computing surface can recognize and identify objects that are placed onto the screen. In Microsoft Surface 1.0 , light from objects are reflected to multiple infrared cameras. This allows the system to capture and react to the items placed on the screen . In an advanced version of the technology (Samsung SUR40 with Microsoft PixelSense), the screen includes sensors, instead of cameras to detect what touches the screen . On this surface, you could create digital paintings with paintbrushes based on the input by the actual brushtip. The system is also programmed to recognize sizes and shapes and to interact with embedded tags e.g. a tagged namecard placed on the screen will display the card’s information. Smartphones placed on the ...

How technology will change the future of work

By
How many of us can say, with certainty, what jobs we would choose if we were kids today? The pace of technological change in the time I’ve been in work is only a shadow of what we will see over the next 15 to 20 years. This next wave of change will fundamentally reshape all of our careers, my own included. It’s estimated that some 65% of children entering primary schools today will likely work in roles that don’t currently exist . We expect the pace of change in the job market to start to accelerate by 2020. Office and administrative functions, along with manufacturing and production roles, will see dramatic declines accounting for over six million roles over the next four years . Conversely, business and financial operations along with computer and mathematical functions will see steep rises. There is a central driver for many of these transformations, and it is technology. Artificial intelligence, 3D printing, resource-efficient sustainable production and robotics will f...

Wearable Computer

By
Wearable Computer As the name suggests, wearable computers are electronic devices which you can wear on you like an accessory or apparel . It can be a pair of gloves, eyeglasses, a watch or even a suit. The key feature of wearable UI is that it should keep your hands free and will not hinder your daily activities. In other words, it will serve as a secondary activity for you, as and when you wish to access it. (Image Source: sonymobile.com ) Think of it as having a watch that can work like a smartphone. Sony has already released an Android-powered SmartWatch earlier this year that can be paired with your Android phone via Bluetooth. It can provide notifications of new emails and tweets. As with all smartphones, you can download compatible apps into Sony SmartWatch for easy accessibility. Expect more wearable UI in the near future as microchips bearing smart capabilities grow nano-smaller and be fitted into everyday wear.
