Graffiti works with a simplified version of the existing alphabet. The user enters pre-defined strokes for each letter, Graffiti then translates that stroke into the corresponding text character on the computer screen.
Because Graffiti works with a basic modification of the existing alphabet, most users become competent with Graffiti in less than 20 minutes. Graffiti is being supported as an optional text entry method by a wide range of handheld computing developers including: Apple Computer, Casio Corp. By increasing the uniqueness of each character, Palm has developed a system which is highly accurate, therefore addressing the major frustration of current handheld computer users: predictability.
This results in an immediate response for the user. Each time the user writes a stroke, the electronic ink is instantly translated into a text character. The user gains control by immediately verifying the information, which provides the opportunity to instantly correct mistakes. The sensation of using Graffiti is very similar to typing on a keyboard. When the user hits a key strokes a character a letter appears on the screen.
Graffiti covers many characters which are impossible to achieve with current recognition technology including accented characters, punctuation and symbols. Capitalization, punctuation, numbers and symbols are handled similarly to a keyboard. The letter following the upstroke is then capitalized. These strokes are never confused by the Graffiti system. Because Graffiti provides an immediate response to each stroke of the pen, user do not need to write out words or sentences, but rather can write one character on top of another.
By not looking at the screen, the Graffiti user can concentrate on the speaker or the document they are transcribing. Further, since the user can write in a small area on the screen, wide acceptance of Graffiti may result in the development of smaller devices with smaller screens for entering data.
With ShortCuts a user can build a library of frequently used phrases, and easily recall any of them with a few strokes of the pen. For instance, the user may create a thank you note which they often fax to customers. Future models would go on to be some of the first smartphones ever made.
Palm Computing, Inc. When these other devices failed, Palm embarked on the journey to create their own, culminating in the release of the Palm Pilot in Though primitive by today's standards, the Pilot featured very competitive specs for the time, offering a 16 MHz processor; upgradeable memory starting at KB; a x monochrome display; and most importantly, a resistive touchscreen supporting stylus input for navigation and handwriting recognition through Palm's Graffiti software.
Future models would go on to offer faster processors, more memory, and vibrant color displays up to x in resolution. Unlike modern smartphones, Palm was designed to be a companion to a PC, featuring desktop software for synchronizing contacts, to-do lists, memos, calendars, and even emails and Microsoft Office documents. Some could even connect to the internet directly, or store images, music, and movies on external SD cards.
The operating system, simply named Palm OS, was incredibly flexible, and neatly balanced closed source code with an open ecosystem. Nearly any part of the OS could be modified by third-party apps, leading to a thriving catalog of enhancements and addons, not to mention custom spins on the user experience by hardware manufacturers like Sony, Fossil, and Tapwave. For more than a decade, Palm OS was a hotbed for innovation and creativity.
Unfortunately, in the late s, Palm Computing suffered under a variety of acquisitions and subsequent mismanagement that left Palm OS to stagnate. In , the company emerged again with webOS, a competitor to Apple and Android smartphones with modern hardware and software features.
Some electronic engineering and the manufacture of Apple's MessagePad devices was undertaken in Japan by the Sharp Corporation. The devices ran the Newton OS. A personal digital assistant PDA , also known as a handheld PC , is a variety mobile device which functions as a personal information manager. PDAs have been mostly displaced by the widespread adoption of highly capable smartphones, in particular those based on iOS and Android.
Palm OS is a discontinued mobile operating system initially developed by Palm, Inc. Palm OS was designed for ease of use with a touchscreen-based graphical user interface. It is provided with a suite of basic applications for personal information management. Later versions of the OS have been extended to support smartphones. Several other licensees have manufactured devices powered by Palm OS. Optical character recognition or optical character reader OCR is the electronic or mechanical conversion of images of typed, handwritten or printed text into machine-encoded text, whether from a scanned document, a photo of a document, a scene-photo or from subtitle text superimposed on an image.
Palm, Inc. They were the designer of the PalmPilot, the first PDA successfully marketed worldwide, as well as the Treo , one of the first smartphones. The company was also responsible for the first versions of webOS, the first multitasking operating system for smartphones, and enyo. Palm devices are often remembered as "the first wildly popular handheld computers," responsible for ushering in the smartphone era.
Handwriting recognition HWR , also known as Handwritten Text Recognition HTR , is the ability of a computer to receive and interpret intelligible handwritten input from sources such as paper documents, photographs, touch-screens and other devices. The image of the written text may be sensed "off line" from a piece of paper by optical scanning or intelligent word recognition.
Alternatively, the movements of the pen tip may be sensed "on line", for example by a pen-based computer screen surface, a generally easier task as there are more clues available.
A handwriting recognition system handles formatting, performs correct segmentation into characters, and finds the most plausible words. The PenPoint OS was a product of GO Corporation and was one of the earliest operating systems written specifically for graphical tablets and personal digital assistants.
It was never widely adopted. He has since turned to work on neuroscience full-time, founding the Redwood Center for Theoretical Neuroscience in and Numenta in Hawkins is currently Chief Scientist at Numenta, where he leads a team in efforts to reverse-engineer the neocortex and enable machine intelligence technology based on brain theory. Hawkins is the author of On Intelligence which explains his memory-prediction framework theory of the brain.
Versions for some handheld platforms were also released and licensed to some companies. Graffiti 2 made its debut in Palm OS 4.
Inkwell , or simply Ink , is the name of the handwriting recognition technology developed by Apple Inc. Introduced in an update to Mac OS X v The technology made its debut as "Rosetta", an integral feature of Apple Newton OS, the operating system of the short-lived Apple Newton personal digital assistant.
