Slashdot: Scientists Make a Touch Tablet That Rolls and Scrolls

Scientists Make a Touch Tablet That Rolls and Scrolls
Published on September 01, 2018 at 05:33AM
An anonymous reader quotes a report from TechCrunch: Research scientists at Queen's University's Human Media Lab have built a prototype touchscreen device that's neither smartphone nor tablet but kind of both -- and more besides. The device, which they've christened the MagicScroll, is inspired by ancient (papyrus/paper/parchment) scrolls so it takes a rolled-up, cylindrical form factor -- enabled by a flexible 7.5inch touchscreen housed in the casing. This novel form factor, which they made using 3D printing, means the device can be used like an erstwhile Rolodex (remember those?!) for flipping through on-screen contacts quickly by turning a physical rotary wheel built into the edge of the device. (They've actually added one on each end.) Then, when more information or a deeper dive is required, the user is able to pop the screen out of the casing to expand the visible display real estate. The flexible screen on the prototype has a resolution of 2K. So more mid-tier mobile phone of yore than crisp iPhone Retina display at this nascent stage. The scientists also reckon the scroll form factor offers a pleasing ergonomically option for making actual phone calls too, given that a rolled up scroll can sit snugly against the face. The team posted a video showing the prototype in action. They will be presenting the project at the MobileHCI conference on Human-Computer Interaction in Barcelona next month.

Slashdot: AT&T Says Leaked Data of 70 Million People Is Not From Its Systems

AT&T Says Leaked Data of 70 Million People Is Not From Its Systems Published on March 20, 2024 at 02:15AM An anonymous reader quotes a report from BleepingComputer: AT&T says a massive trove of data impacting 71 million people did not originate from its systems after a hacker leaked it on a cybercrime forum and claimed it was stolen in a 2021 breach of the company. While BleepingComputer has not been able to confirm the legitimacy of all the data in the database, we have confirmed some of the entries are accurate, including those whose data is not publicly accessible for scraping. The data is from an alleged 2021 AT&T data breach that a threat actor known as ShinyHunters attempted to sell on the RaidForums data theft forum for a starting price of $200,000 and incremental offers of $30,000. The hacker stated they would sell it immediately for $1 million. AT&T told BleepingComputer then that the data did not originate from them and that its systems were not breached. ...

Slashdot: US Plans $825 Million Investment For New York Semiconductor R&D Facility

US Plans $825 Million Investment For New York Semiconductor R&D Facility Published on November 02, 2024 at 03:00AM The Biden administration is investing $825 million in a new semiconductor research and development facility in Albany, New York. Reuters reports: The New York facility will be expected to drive innovation in EUV technology, a complex process necessary to make semiconductors, the U.S. Department of Commerce and Natcast, operator of the National Semiconductor Technology Center (NTSC) said. The launch of the facility "represents a key milestone in ensuring the United States remains a global leader in innovation and semiconductor research and development," Commerce Secretary Gina Raimondo said. From the U.S. Department of Commerce press release: EUV Lithography is essential for manufacturing smaller, faster, and more efficient microchips. As the semiconductor industry pushes the limits of Moore's Law, EUV lithography has emerged as a critical technology to ...

Slashdot: AT&T, T-Mobile Prep First RedCap 5G IoT Devices

AT&T, T-Mobile Prep First RedCap 5G IoT Devices Published on October 15, 2024 at 03:20AM The first 5G Internet of Things (IoT) devices are launching soon. According to Fierce Wireless, T-Mobile plans to launch its first RedCap devices by the end of the year, while AT&T's devices are expected sometime in 2025. From the report: All of this should pave the way for higher performance 5G gadgets to make an impact in the world of IoT. RedCap, which stands for reduced capabilities, was introduced as part of the 3GPP's Release 17 5G standard, which was completed -- or frozen in 3GPP terms -- in mid-2022. The specification, which is also called NR-Light, is the first 5G-specific spec for IoT. RedCap promises to offer data transfer speeds of between 30 Mbps to 80 Mbps. The RedCap spec greatly reduces the bandwidth needed for 5G, allowing the signal to run in a 20 MHz channel rather than the 100 MHz channel required for full scale 5G communications.
