The new technologies are part of a raft of new features introduced by Samsung so the smartphone could be used without touching the screen. The company has enabled gesture recognition technologies in which a hand can be hovered over the screen to preview news, email, files in a folder and information in calendars. Gestures can also be used to scroll in browser windows, switch between browser tabs, or even accept phone calls.
"We've done a lot of work in terms of discoverability and usability of these features," Blackard said.
The Galaxy S 4 will be available from 327 operators in 155 countries starting at the end of April, though no specifics on its price or shipping were provided. The smartphone has a super AMOLED display with density of 441 pixels-per-inch, a 13-megapixel rear camera and a 2-megapixel front camera. It weighs 130 grams, is 7.9 millimeters thick and depending on the market, may come with a 1.9GHz quad-core processor or 1.6GHz Samsung Exynos 5 eight-core processor. Other features include up to 64GB of storage and 802.11ac Wi-Fi.
