The history of tablet computers and the associated special operating software is an example of pen computing technology, and thus the development of tablets has deep historical roots. In addition to many academic and research systems, there were several companies with commercial products in the 1980s: Pencept, Communications Intelligence Corporation, and Linus were among the best known of a crowded tablet pc android 4.0 user manual pdf. The tablet computer and the associated special operating software is an example of pen computing technology, and the development of tablets has deep historical roots.
The first patent for a system that recognized handwritten characters by analyzing the handwriting motion was granted in 1914. Tablet computers appeared in a number of works of science fiction in the second half of the 20th century, with the depiction of Arthur C. Steve Jobs of Apple envisioned in a 1983 speech an “incredibly great computer in a book that you can carry around with you and learn how to use in 20 minutes”. Star Trek: The Next Generation featured extensive use of tablet computers. In 1986, Hindsight, a startup in Enfield CT, developed the Letterbug, an 8086-based tablet computer for the educational market. Prototypes were shown at trade shows in New England in 1987, but no production models ever came out. In September 1987, Apple Computer sponsored a contest to design “the personal computer of the year 2000”.
In 1989, the GRIDPad tablet became available, based on an 8086 CPU. The founder of GRID, Jeff Hawkins, later went on to develop the Palmpilot. The 1991, Atari ST-PAD Stylus was demonstrated but did not enter production. The Compaq Concerto was released in 1993 with a Compaq-modified version of MS DOS 6.
Windows for PEN, with pen-entry and Wacom compatibility. Functionally the Concerto was a full featured laptop that could operate in pen-mode when the keyboard was removed. In 1994 media company Knight Ridder made a concept video of a tablet device with a color display and a focus on media consumption. The company didn’t create it as a commercial product because of deficiencies of weight and energy consumption in display technology. In 1996, The Webbook Company announced the first Internet-based tablet, then referred to as a Web Surfboard, that would run Java and utilize a RISC processor.
Again in 1996, Fujitsu released the Stylistic 1000 tablet format PC, running Microsoft Windows 95, on a 100 MHz AMD486 DX4 CPU, with 8 MB RAM offering stylus input, with the option of connecting a conventional Keyboard and mouse. In 1999, Intel announced a StrongARM based touch screen tablet computer under the name WebPAD, the tablet was later re-branded as the “Intel Web Tablet”. In April 2000, Microsoft launched the Pocket PC 2000, utilising their touch capable Windows CE 3. In 1999, Microsoft attempted to re-institute the then decades old tablet concept by assigning two well-known experts in the field, from Xerox Palo Alto Research Center, to the project. In 2000, Microsoft coined the term “Microsoft Tablet PC” for tablet computers built to Microsoft’s specification, and running a licensed specific tablet enhanced version of its Microsoft Windows OS, popularizing the term tablet PC for this class of devices. In 2002, original equipment manufacturers released the first tablet PCs designed to the Microsoft Tablet PC specification.
This generation of Microsoft Tablet PCs were designed to run Windows XP Tablet PC Edition, the Tablet PC version of Windows XP. Tablet PCs failed to gain popularity in the consumer space because of unresolved problems. Before the advent of the aforementioned software, many users had to rely on on-screen keyboards and alternative text input methods like Dasher. A number of Linux-based OS projects are dedicated to tablet PCs. Since all these are open source, they are freely available and can be run or ported to devices that conform to the tablet PC design. January 2009, as the Palm OS, webOS was purchased by HP to be their proprietary operating system running on the Linux kernel.
