The iPhone 5S, stylized iPhone 5s, is a touchscreen-based smartphone developed by Apple Inc. It is part of the iPhone line, and was released on September 20, 2013. Apple held an event to formally introduce the phone (and its mid-range counterpart, the iPhone 5C) on September 10. Like the iPhone 4S, the 5S is a revised version of its predecessor, the iPhone 5, but also incorporates a 64-bit Apple A7 processor and a built-in fingerprint sensor called Touch ID on its updated home button.
The 5S ships with iOS 7, the seventh version of Apple's iOS mobile operating system, which is based on the concept of direct manipulation, using multi-touch gestures. Interface control elements consist of sliders, switches, and buttons. Interaction with the OS includes gestures such as swipe, tap, pinch, and reverse pinch, all of which have specific definitions in the context of the iOS operating system and its multi-touch interface. New features in iOS 7 include Control Center, AirDrop, iTunes Radio, and a new flat design directed by Jonathan Ive.
Reviews for the iPhone 5S were generally positive; some reviewers called it the best smartphone on the market. While Touch ID was praised as a major market changer, many commentators believed that iOS 7 was the most major update to the smartphone line. The 64-bit Apple A7 was also favored. Pundits claimed that it is a catalyst for various new applications from developers.
Google Glass (styled "GLΛSS") is a wearable computer with an optical head-mounted display (OHMD) that is being developed by Google in the Project Glass research and development project, with a mission of producing a mass-market ubiquitous computer. Google Glass displays information in a smartphone-like hands-free format, that can communicate with the Internet via natural language voice commands. While the frames do not currently have lenses fitted to them, Google is considering partnerships with sunglass retailers such as Ray-Ban or Warby Parker, and may also open retail stores to allow customers to try on the device. The Explorer Edition cannot be used by people who wear prescription glasses, but Google has confirmed that Glass will eventually work with frames and lenses that match the wearer's prescription; the glasses will be modular and therefore possibly attachable to normal prescription glasses.
Glass is being developed by Google X, which has worked on other futuristic technologies such as driverless cars. The project was announced on Google+ by Project Glass lead Babak Parviz, an electrical engineer who has also worked on putting displays into contact lenses; Steve Lee, a product manager and "geolocation specialist"; and Sebastian Thrun, who developed Udacity as well as worked on the autonomous car project. Google has patented the design of Project Glass. Thad Starner, an augmented reality expert, is a technical lead/manager on the project.
