Touchscreens starting to be seen on digital cameras
A touchscreen is a visual electronic display that will detect the touch and location and presence in a display area. The term typically refers to touching a display with a finger. Touchscreens also have the ability to sense other objects like a stylus. Touchscreens have become common in
devices like smartphones,
game consoles, tablet computers and all-in-one computer systems
and are starting to be seen in more compact
digital camera interfaces.
The touchscreen features two primary attributes. Number one, it enables a person to directly interact with what's on the display, rather than reacting indirectly with a touchpad or mouse pointer. Number two, it lets a person interact without needing any intermediate devices needing to be hand held (other than using a stylus, optional for most touchscreens). Touchscreen displays may be connected to a computer, or to a network acting as a terminal. They have also played a major part in the design and
layout of digital devices like personal digital assistants (PDAs), satellite navigation devices, smartphones, and video games.
Subsequently, touchscreens have become common in everyday life. Companies are using touchscreens in kiosk systems for tourist and retail environments, point of sale devices, PDAs and ATMs, where a stylus can be used at times to control the GUI and for entering data.
Until very recently, most of the touchscreens designed for consumers could only discern one contact point at a time, while few have had any capability to discern how hard it is being touched. This has begun to change since multi-touch technology is getting more
The attractiveness of smartphones, portable video games, tablet computers, and numerous other kinds of information devices is pushing the acceptance and demand for everyday touchscreens, as a part of portable and interactive electronics. While a minimal smooth surface, with direct interaction without the further need for hardware devices such as a mouse or keyboard between the operator and content, fewer accessory devices are necessary.
Most of the patents on touchscreens were filed in the 1970s & 1980s past the expiration dates. Manufacturing of touchscreen components along with design og products are no longer being encumbered by legalities or royalties with any regard to patents, subsequently touchscreen-enabled displays have become widespread.
Development of multiple point touchscreens have allowed for tracking of multiples finger being placed upon the screen; thus, functions that need more than a single finger have become possible. These devices also permit multiple users to concurrently act together with the touchscreen .
The expanded use of touchscreens, along with the marginal touchscreen technology cost is routinely included in the merchandise that incorporate its use have nearly been eliminated. Touchscreens are at the proven reliability point. Thus, one can find touchscreen displays nearly everywhere, like automobiles, airplanes, machine control systems, gaming consoles, appliances, plus handheld display devices such as multi-touch iPhones and the Nintendo DS. The mobile device touchscreen market has projected $7 billion in the U.S. alone in 2012.
The capability to precisely point on the monitor is also progressing with the emergence of tablet screen hybrids.
Some touchscreens, mostly those being used in smartphones, employ plastic protectors to inhibit scratches that could be created with day-to-day use.
