A CES 2014 Flashback: The Folly of Curved TV Screens

At one time, five years ago, curved TV screens were all the rage. Every TV manufacturer jumped on the bandwagon, fearful of being left out. Today, we know it was a fad. A folly. A technical dead end. Recently, ars technica took us back in time, via Twitter, to their prescient analysis. After a good technical roundup, “The flat-out truth on curved TVs” ars concluded:

The mishmash of arguments for a curved TV isn’t necessarily an indictment of the value of curved TV. This would not be the first time that manufacturers obscured the technical or scientific reasons for a decision because they think it’s too hard to explain to consumers. It may be easier to latch onto words like “immersive” and “theatrical” and hope no one asks the hard questions.

CES - Scosche BaseLynx Modular Wireless Charging Station Organizes and Charges Your Devices

Scosche’s CES booth was again full of great new devices for managing your devices in both your home and car, and the highlight to us was their new BaseLynx modular wireless charging station. Available modules include a Qi fast-charge dock, an Apple Watch dock, powered end-cap, and a vertical power station which holds three wired devices. The end-cap has a 12V USB-A and 18W USB-C PD outlet, and the power station has that plus a second USB-A port. You can mix-and-match modules to serve your needs – including just using one if you like – and BaseLynx is engineered to prevent over- or under-voltage, surging, and overheating. Pricing has not yet been announced, and BaseLynx is due to be available this coming spring.

CES - Ultrahaptics Uses Ultrasound for Touchless Gesture Control, Haptic Feedback, and 3D Viewing

One of the coolest things I found at CES this year was Ultrahaptics technology, allowing for gesture control and haptic feedback using only ultrasound. Touching nothing, I was able to control and manipulate an on-screen “object”, and even feel it all through the magic of ultrasound waves. They also had a demo using their tech that tracks your face and eyes to project and focus a 3D image without the need for any glasses. I talked a bit about it on the show floor:
