when did touch screen phones first come out
1992

In 1990, HCIL demonstrated a touchscreen slider, which was later cited as prior art in the lock screen patent litigation between Apple and other touchscreen mobile phone vendors (in relation to ). In 1991–1992, the Sun Star7 prototype PDA implemented a touchscreen with inertial scrolling. In 1993, IBM released the IBM Simon the first touchscreen phone. An early attempt at a handheld game console with touchscreen controls was Sega's intended successor to the Game Gear, though the device was ultimately shelved and never released due to the expensive cost of touchscreen technology in the early 1990s. title: Form factor (mobile phones) text: that the damage is so serious as to have rendered the device permanently unusable. A slate or slade (UK English) is a smartphone form with few to no physical buttons, instead relying upon a touchscreen and an onscreen keyboard. The first commercially available touchscreen phone was a brick phone, the IBM Simon Personal Communicator, released in 1994. The iPhone, which was released in 2007, is largely responsible for the influence and achievement of this design as it is currently conceived. Some unusual "slate" designs include that of LG New Chocolate (BL40), or the Samsung Galaxy Round, which is curved.

Although Android's adoption was relatively slow at first, it started gaining widespread popularity in 2010, and in early 2012 dominated the smartphone market share worldwide, which continues to this day. Android and iPhone devices popularized the smartphone form factor based on a large capacitive touchscreen, and led to the decline of earlier, keyboard- and keypad-focused platforms. Microsoft, for instance, discontinued Windows Mobile and started a new touchscreen-oriented OS from scratch, called Windows Phone. Nokia abandoned Symbian and partnered with Microsoft to title: Smartphone text: Early smartphones were marketed primarily towards the enterprise market, attempting to bridge the functionality of standalone personal digital assistant (PDA) devices with support for cellular telephony, but were limited by their battery life, bulky form factors, and the immaturity of wireless data services. In the 2000's, BlackBerry, Nokia's Symbian platform, and Windows Phone began to gain market traction, with models often featuring QWERTY keyboards or resistive touchscreen input, and emphasizing access to push email and wireless internet. Since the unveiling of the iPhone in 2007, the majority of smartphones have featured thin, slate-like form factors, with large, capacitive screens with title: Touchscreen text: cognitive psychology and human physiology. Guidelines for touchscreen designs were first developed in the 1990s, based on early research and actual use of older systems, typically using infrared grids—which were highly dependent on the size of the user's fingers. These guidelines are less relevant for the bulk of modern devices which use capacitive or resistive touch technology. From the mid-2000s, makers of operating systems for smartphones have promulgated standards, but these vary between manufacturers, and allow for significant variation in size based on technology changes, so are unsuitable from a human factors perspective. Much more important is the accuracy humans
