A tablet PC is a special notebook, particularly lightweight, with no hinged parts. The term is not protected by trademark law, so it is a class of device that can be held in the hand and operated that way.
Modern designs dispense with a keyboard; data is entered in dialog by touching the display surface with a pen or fingertip. The touch-sensitive screen either provides a virtual keyboard or shows icons and menus for selection. Usually a tablet PC is also equipped with software for handwriting recognition.
history
Development of pen-operated computers
The idea of the pen-operated computer ( penabled PC or pen computer ) existed long before the tablet PC. The term Tablet PC itself was introduced by Microsoft in 2001 . The first concept for a portable computer with an intuitive user interface was the planned Dynabook in the 1960s and 1970s . The first software for handwriting recognition was developed by Charles Elbaum as early as the 1980s . One of the first computer with true pen input in 1993 was the Newton by Apple , the forerunner of today's PDAs .
In 1991 the pen was seen as a serious alternative to the mouse for the first time . B. Microsoft brought the pen extensions for Windows 3.1 on the market. Between 1992 and 1994 several manufacturers (for example Compaq , Fujitsu , IBM , NCR , Samsung and Toshiba ) released suitable hardware that ran under the two available operating systems Windows for Pen Computers or PenPoint (from GO Corporation). Toshiba's DynaPad T100X was the first real forerunner of tablet PCs. The ThinkPad was, as the name suggests, originally called Slate planned. Since these concepts were not given great market opportunities, they disappeared back into the drawer at NCR and Samsung. Pen application and hardware pioneers like GRiD and GO Corporation have been bought or liquidated. Compaq, IBM, NEC and Toshiba all discontinued consumer pen-based products in 1994/1995. However, pen-operated computers continued to be manufactured and sold for industry. One example is the SIMpad (2001).
Microsoft's Tablet PC standard
Since Microsoft continued to stick to a concept of pen-operated computers, pen- based input devices were repeatedly presented over the years at their computing in the future presentations, and the Tablet PC extension for the Windows XP operating system was finally published in 2002 . At the same time, various housing designs for tablet PCs were presented. Since the launch of the Windows XP Tablet PC Edition , a large number of end devices have been available, including from Dell , Fujitsu-Siemens , Hewlett-Packard , Lenovo and Toshiba. The original idea of the tablet PC based on the Microsoft standard was that a tablet PC should primarily be operated by writing on the screen with a pen. An inductive digitizer records the pen movement like in a graphics tablet. Operation with fingers was not intended in the beginning, which is why digitizers for pen operation are still common on tablet PCs today.
Since 2005, according to Microsoft's specifications, touchscreens that allow operation with fingers (also in connection with UMPCs ) may be used. The background to this was that most touch-sensitive displays were initially unable to differentiate between placing a hand on the display and operating it with a pen or finger, which led to problems when writing. Further requirements were that the device must be able to start quickly from standby mode and comply with the legacy free design (no external serial or parallel interfaces ). In addition, the screen content can be rotated using a button for portrait and landscape format, so that you can work in portrait format as usual on writing pads. For use in corporate environments, there is a button for the Ctrl-Alt-Del function to log on to Windows and to call up the task manager. Originally slate , convertible or hybrid were intended as designs (see section Types of tablet PCs ).
However, Microsoft's definition only describes which requirements a tablet PC must meet in order for it to be sold with the Tablet PC Edition of Windows XP. The subsequent versions of Windows provided the tablet functions for all devices with a suitable input device.
Tablets
In addition to devices based on Microsoft's Tablet PC standard, there are also devices that are sold with Linux or macOS . Due to the use of an open hardware architecture, the operating systems are usually interchangeable with one another.
In addition to tablet PCs, a similar device category has established itself in the form of tablets , which consists of finger-operated embedded systems in slate design . These devices are based on a closed hardware architecture with a fixed operating system, which, in contrast to tablet PCs, are primarily intended for media consumption. This device category was introduced by Apple in early 2010 with the iPad .
hardware
Tablet PCs represent a device category between laptops on the one hand and PDAs or smartphones on the other hand. Tablet PCs in the classic sense have the same range of functions as notebooks and have a similar structure. The main differences are in the design of the housing and in the display that can be operated with a pen and touch. The remaining components such as the processor, hard disk and main memory correspond to the usual PC standards to enable full compatibility with software for x86 processors . More recent developments, such as the iPad , on the other hand, are based on the technology of smartphones and transfer this to the device class of tablet computers . Since tablet PCs are primarily intended for mobile use, they are roughly the size of subnotebooks or netbooks . Compared to PDAs, the biggest difference is the larger and heavier design. In addition, a digitizer is often used in tablet PCs instead of the touch-sensitive display in PDAs.
Pen-operated display
Tablet PCs can be operated by writing on the screen with the pen, with an inductive digitizer recording the pen movement. In contrast to the touchscreen, the screen is insensitive to touch, which means that the heel of the hand can rest on the screen while writing without disturbing the recognition of the pen position. However, in contrast to a PDA, it can only be operated with a suitable special pen. These special pens have additional functions, however, such as the strength of the pressure and the pen inclination when writing, and there are freely programmable buttons.
The technology used in the display corresponds to that of graphics tablets . This goes so far that many current tablet PCs have integrated recognition technology from Wacom , a graphics tablet specialist. For this reason, all applications that are intended for use with graphics tablets can also be used with tablet PCs.
There are two types of pens used:
- With battery: The pen can differentiate between 64 pressure levels, the spatial resolution of the pen on the display is relatively low.
- without battery: the pen can have more than 64 pressure levels (current standard: 254 levels). differ, the display is higher resolution.
Since 2005, according to Microsoft's specifications, touchscreens can also be used, although the display must be able to process several inputs at the same time. This is necessary in order to distinguish whether the user wants to enter something with the stylus (or the finger) or just puts his hand down. An input pen without electronics is used for a touchscreen .
Housing designs
The three original concepts of tablet PCs are convertible , hybrid and slate . Since 2006, the UMPCs have been another form of portable computer that can only be operated with the fingers.
Convertible
The most common design for tablet PCs is the convertible (Engl. For convertible ). In principle, the user has the same functionality as a notebook - especially a keyboard - and can also rotate the display 180 degrees and then fold the screen up over the keyboard so that the convertible with the stylus looks like a notepad can be used. This design thus combines the advantages of tablet PCs and conventional notebooks. The higher weight and the significantly greater height of the folded device have a disadvantage compared to the other designs, which make longer use on the arm difficult. Nevertheless, convertibles are more common because the built-in keyboard gives users the security of being able to work with the familiar and faster input device at any time. The pen can also be used in notebook mode.
Slate
As Slate (Engl. For slate ), a tablet PC is called, which is limited to the actual usage of pen and no keyboard has built. In contrast to the notebook, the case consists of a single block instead of being divided into a keyboard and display block. The compact and weight-reduced design of these devices makes them very mobile and allows you to work on your arm for longer. The lack of a keyboard is not a problem, as all tablet PCs can only be operated using the pen with handwriting recognition and the function keys attached to the housing. If necessary, drives and keyboard must be connected as external devices (usually via USB / Bluetooth or a docking station ).
A device that externally corresponds to this design was introduced by Apple in 2010 with the iPad . However, it differs in the lack of pen input and the lack of connections for external input devices. In addition, by using a stripped-down operating system ( Apple iOS ), only approved applications can be used. As other manufacturers subsequently brought similar devices onto the market, the new device category of tablet computers emerged .
Hybrid
A rare but more common expectant design is the hybrid (Engl. For hybrid ), the properties of Convertible and Slate connects. The keyboard can be stowed behind the screen, just like with the convertible , but it is also completely removable, which turns the device into a "pure" slate .
- The three Compaq / HP models (TC1000, TC1100 and Compaq Concerto) are no longer in production.
- The Chinese manufacturer Lenovo has announced a hybrid device called the ideaPad U1 for summer 2010 , on which Windows 7 and Linux in slate mode will be used.
- (Another slate developed by Asus in 2011 under the name Transformer is a tablet computer with the Android operating system . It is not a Microsoft tablet PC.)
- Also Samsung has developed a palmtop computer.
- Microsoft has its own Microsoft Surface line with hybrid computers with 10.6 and 12 inch screen diagonals on offer (as of 2014)
- With the Stylistic Q702, the Japanese-German manufacturer Fujitsu has an 11.6 inch (29.5 cm) hybrid with an Intel i5 vPro processor and Windows 7 or 8 Professional in its range (as of 2014).
UMPC
An Ultra-Mobile PC is not just a tablet PC, but a fully-fledged portable computer that can be operated entirely with the fingers and is only slightly larger than a PDA . A version of Windows XP Tablet PC Edition or Windows Vista can run on a UMPC , as a pen can also be used for input. A UMPC is thus a tablet PC . UMPCs can be used for many tasks, for example as a multimedia player or navigation device with all the possibilities of a PC-based platform.
Pen operation and electronic ink
First of all, the pen on the tablet PC replaces the mouse, similar to input using a graphics tablet on a conventional PC. A single tap on the screen corresponds to a mouse click, a double tap corresponds to a double click. The right mouse click is simulated by tapping and holding, similar to the Pocket PC, or it can be placed on one of the most common buttons on the pen. One of the main features of tablet PCs is the ability to enter text with the pen, which is not available on all tablet PCs:
The idea behind the (Windows XP) Tablet PC was to use the pen on the screen to make the user feel like they were working with pen and paper. To do this, the system calculates Bézier curves from the pen trace on the screen , which mathematically represent what has been written. Depending on the pen and the capabilities of the display, pressure and pen inclination can be evaluated in addition to the position of the pen. The curves are then shown in a grid on the display. This creates the feeling for the user that he is writing or drawing on the screen.
Many programs for tablet PCs are able to convert this ink into text. Depending on the approach, this happens automatically in the background or upon user request. The freehand input can also be searched for keywords or can be processed further as normal text in other programs. However, the pen input is less suitable for purely extensive text input, since the user is usually faster with the keyboard. However, this type of input is advantageous for complex mathematical formulas, sketches or for commenting on documents.
Operating systems
An extended version of Windows XP, the Windows XP Tablet PC Edition , was originally used as the operating system . After about two years another version appeared, the Windows XP Tablet Edition 2005 , which is based on Windows XP Service Pack 2. Almost all components such as the tablet input area and the entire handwriting recognition have been revised. The successor, Windows Vista, no longer has a special version for Tablet PC , since the Tablet PC functions are natively contained in all versions except Home Basic and Starter.
Thanks to the standard hardware and compatibility with graphics tablets , the pen can also be used with other operating systems such as Linux . The Lycoris company, for example, offered a suitably adapted Linux version with the required drivers and additional functions for pen input. Mac OS X supports pen input and handwriting recognition natively, but suitable end devices are currently only available as modified versions of the standard hardware from third-party providers.
In order to be able to use applications without a keyboard that are not specially adapted for tablet PCs, there is a freehand input bar in all operating systems . In Windows, this appears as soon as a text field has been selected with the pen and enables the user to enter text with the pen. Handwriting recognition or the on- screen keyboard can be used.
The Tablet PC Edition of Windows XP also includes the Windows Journal program, which enables you to write and draw as you would on a normal pad of paper. All the usual options of computer programs are available, i.e. search, undo, copy, paste (of images and text), change format, move, scale, etc. The Journal Viewer enables journal files to be displayed on non-tablet PCs .
With Windows Vista , the functionality for tablet PCs has been expanded. Gesture recognition and the integration of a virtual mouse, which also enables the operation of very small screens such as those used with UMPCs, are new . The handwriting recognition is adaptive in Windows Vista and no longer just adaptable by expanding the dictionary. Under Windows Vista, in contrast to Windows XP Tablet PC Edition , executed clicks are visualized by lighting up circles in order to enable better feedback.
In Windows 7 , Microsoft has revised the input area, including enlarging the keys on the virtual keyboard and introducing corrective gestures. Handwriting recognition can now also be trained in German by the user. A math input area allows you to write math formulas with the pen.
There are alternatives to the extensions of Windows, for example riteScript is an alternative to the Microsoft Tablet PC input area with its own handwriting recognition. With this program, handwritten text entry is possible on the complete screen.
Handwriting recognition
The handwriting recognition when entering with a pen directly on the PC differs significantly from the recognition of the text in an OCR system. With offline text recognition in an OCR system, a template must first be converted into a digital rastered image, whereas online handwriting recognition in a tablet PC can directly access the curves written with a pen. This provides information such as the speed of the individual sections of the curves and the sequence of the individual curves, which can no longer be reconstructed with offline text recognition.
The curves are saved as a sequence of points that go through a series of correction operations (line alignment, normalization of the size, alignment of the letters). Then the characteristics of the writing, more precisely the trajectories of the curves, are extracted. Then probabilities for different words are calculated using hidden Markov models from the sequence of individual letters and groups of letters ( N-grams ), which are mutually dependent in their appearance. Depending on the quality of the models of the letters (groups) and the scope of the dictionary, the recognized words can then be output.
Use of gestures
The lack of a keyboard on some models makes it difficult to use keyboard shortcuts. In principle, many key combinations can be reached via the screen keyboard, but the advantages such as speed and easy access to the underlying functions are lost. Similar to mouse gestures , i.e. drawing figures with a mouse or, in this case, the pen, the user can trigger various actions with defined figures. Some programs support gestures natively, but specialized programs often do this. In Windows Vista, some gestures are supported directly by the operating system, such as navigating web pages (previous / next) or scrolling through documents.
Voice input
Alternatively, the English version of Windows XP Tablet Edition and all versions of Windows Vista also offer the option of voice input using the microphone in all Tablet PCs . In contrast to the built-in speech recognition in Windows XP Tablet PC Edition , other commercial applications and speech recognition in Windows Vista can usually also be trained and expanded.
Programs with special functions for tablet PCs
In order to be able to use the pen with all its advantages as an input device, the applications must be prepared for it.
Most vector-based drawing programs (e.g. CorelDraw or Inkscape ) support pen input. The pen can also be used in many image editing programs (e.g. Adobe Photoshop ) like a conventional graphics tablet.
Microsoft also has several collections of small software tools ( Microsoft Experience Pack for Tablet PC and Microsoft Education Pack ) with various applications that are intended to show the potential of tablet PCs. This includes, for example, programs for recognizing handwritten mathematical formulas, for writing notes , a crossword puzzle or a program for sticky notes on the desktop. Special plug-ins are also available, for example for Microsoft Office, to expand applications with functions for tablet PCs and to increase productivity. Examples are Tablet Enhancements for Outlook TEO and InkGestures for Word .
Purpose and dissemination
- The Slate models are used, for example, in hospitals during rounds for the direct use of electronic patient files via a wireless network .
- Tablet PCs are suitable as a replacement for interactive whiteboards and overhead projectors in presentations or seminars (together with a video projector ) and for combining computer-aided presentations and conventional teaching methods on a writing board . Microsoft Office PowerPoint supports drawing, writing and highlighting directly in a running slide show .
- Tablet PCs can be used in conferences or sales meetings, as the display is no longer in the way between the conversation partners.
- Tablet PCs can also be used in schools with adapted learning software , for example to help children learn to write.
- They are also used to collect data, for example in the context of recruitment processes in personnel selection .
- Tablet PCs are used by students to supplement the often digitally available scripts and handouts in lectures .
- A wide range of uses are also in professional outdoor areas. For this purpose, the tablet PCs must be designed to be particularly robust - for example for use in emergency medicine.
With the decreasing size of devices and the increasing performance of PDAs, the line between the two categories is becoming increasingly blurred.
A so-called killer application , which would bring about a much faster spread of tablet PCs, was still missing until 2009. The spread was initially slowed down by the very high prices. For example, sales in the third quarter of 2003 were only about 1 percent (92,000 units) of all notebooks sold. However, the prices for the end devices continue to fall and in 2008 were roughly on par with comparable notebooks. Devices have been available for less than € 600 since 2010.

Comparison with standard notebooks
advantages
Tablet PCs enable a more natural form of input - drawing and writing are possible without prior knowledge of using a mouse and keyboard. The use of handwritten notes and sketches increases productivity, as all processes are carried out as if on paper and can be digitally archived. This means that all documents are always available and at the same time searchable without the effort of physically archiving documents.
The gesture recognition enables a great increase in efficiency, since more precise user input is possible with a pen compared to mouse gestures. Using the pen on the screen allows you to work much more precisely than using the mouse. It is therefore a common tool for artists / designers ( digital painting ).
Compared to conventional notebooks, slate tablet PCs are much smaller and lighter and therefore easier to carry with you. In addition, tablet PCs are the only truly mobile computers , as they can be used while standing and operated with one hand - on the underside of some models there is a non-slip, velvety layer and sometimes a strap, which makes it easier to hold. Since the display is designed for constant use with a pen and touch with the hand, the surfaces are usually scratch-resistant and less sensitive to sweat . When used in meetings or conversations with customers, they do not interrupt the visual contact between interlocutors, as they can lie flat on the table.
Since the end of 2015 there has been a new Microsoft tablet PC called Microsoft Surface 4. This embodies the properties of a notebook in a tablet. A keyboard is also available, which can be removed or attached. So you can decide whether you want to use it as a tablet or notebook .
disadvantage
In 2003, tablet PCs were up to 500 euros more expensive than notebooks with the same equipment due to their more complex construction and low sales. In 2010 this price difference had almost disappeared.
The screen sizes are limited by the optimization for mobility. Many models are sold as subnotebooks and are only available with 12 "or 13" displays, some exceptions have 14.1 "displays. The design as subnotebooks and the low weight mean that the slate models in particular often have no optical appearance In addition, the rasterization of the curves drawn in tablet mode uses considerably more computing time than just typing text, which has a negative effect on the battery life, especially in older models.
When writing with the pen, the input speed is much slower than the maximum possible speed with practiced typing .
