Mobile display device with input key and touch-screen for a one-handed combined control

The present invention relates to a digital book, especially for the reproduction of books, newspapers, and magazine information and other documentation and publications in electronic or digital form by means of text, graphic, photo and / or video and audio information on the operation by lay users

The paper consumption and the associated demand for raw materials is growing year after year. The constantly growing number of the population and the growing need for information, but also the self-imposed competition-related communication compulsion cause explosively spreading flood of information, which an immense amount of paper due, therefore, not only pollutes the environment with increasing frequency, but also in terms of transport, storage and recycling costs and respect brings to the provisioning rate of publications an economic disadvantage. Thanks to modern information technology, it has become more possible to produce a great deal of information about your computer to make them available via, for example, Internet, online services and databases or promote in the form of CDs, but these can only PCs, laptops and notebooks by the consumer are consumed, which requires that at least one of the aforementioned computer purchased, installed necessary applications, and their use must be controlled before a first publication can be read.

Vorgenarnnnte reasons and the associated investment costs, the necessary time and the necessary from the perspective of a technical layman special knowledge for installation and operation of hardware and software make it a large part of the population difficult to take advantage of electronic publications. But elderly or disabled people often find no access to computers, because without basic knowledge to operate and handle for a layman is not or only with difficulty or overwhelmed the complexity of the user interface these people.

In addition, laptops and notebooks have through their various drives and variety of input and output interfaces for specific use cases, large volumes and weights, are equipped with a keyboard for the whole each respective character set and a single screen or display. However, there are applications in which on the one hand the relatively costly and area-consuming keyboard is unnecessary and on the other hand standing by a single screen available viewing or viewing / editing surface in certain use cases is too small.

Laptops and notebooks are by their determination as a working tool and the associated design-related or structural features primarily not ergonomic, ie handy and reduced-to-use information means for receiving as of belletristic literature or reading reports, articles, reports and news magazines and newspapers or study of publications in a relaxed position or in situations where no supporting surface is present. Effort and time for the operation are often in no relation to the often spontaneous requirements, which are often still to be done in the short term, for example, to look up information from a lexicon, a phone book or a Femsehzeitschrift.

The publication <patcit id="pcit0001" dnum="US5534888A1"><text>US 5,534,888 A1</text></patcit> is an electronic book is known, which comprises in the manner of a book and a hinged Anzeligeteile these two display parts connecting middle part two.

has a simple ergonomic and compact electronic device as an actual book, Zeitschrift- or newspaper substitute for universal use in different life situations, which can be kept for technical amateurs easy and comfortable to use and creates fewer optical irritation, trouble-free reading and manipulating different publications is not yet known. Selected from the<patcit id="pcit0002" dnum="US5534888A"><text>US 5,534,888</text></patcit> known electronic book requires for use by the user often cumbersome and time-consuming complicated operation operations, since a number of ergonomically inconvenient arranged keys is actuated, whose functionality is predetermined and curtail the available for display space. In one of the<patcit id="pcit0003" dnum="US5534888A1"><text>US 5,534,888 A1</text></patcit> known electronic book takes place, the operator with the aid of an auxiliary display on the outside of the cover image (display elements), which results in the user having to open the electronic book to make settings determine. Furthermore, the keys are only be operated separately. On the back of the central part, a plurality of electrical connectors is arranged, which are hidden behind protective flap and may have to be identified by the user with technical knowledge and making it accessible Hochklapppen the protective covers. When electric cables are connected to the connector can no longer be held on the spine after the manner of a book, or placed on a substrate, the electronic book from the prior art.

The invention is therefore based on the object to provide a digital book of the aforementioned type which is opposite to the prior art despite the compact design for a significantly enlarged display area and on the other an easy to understand for the computer layman benutzerfreundlic he and easy handling ability offers to place him in a position, extensive literature, z. B. to read scientific works, encyclopedias, or belles lettres to well over a conventional bulkier and heavier book to provide the user thus has the advantage, as many pages via for example, only two digital pages in a handy form at least read and / or edit if necessary. The reading and viewing habits of conventional books, magazines and newspaper readers to consider that await the irritation-free as possible viewing of the displayed publications or documents information and which can be repelled by too much indicative of computer technology impression as regards certain forms of controls or due to other excessive demand, as often happens in older people or non-technical users who refuse the use of an electronic or digital book. Making sure is a safe and ergonomic hold and operate in different situations, such as when walking, while lying or if no other support surface is present, as well as a simple and understandable handling and minimal or lack technical knowledge, for example with a disability. Here is a simple and consistent operation despite different applications and vielfälltiger objects are achieved. It is intended to allow rapid and reduced operation with minimal changes in posture while reading.

The basis of the invention is solved by the subject matters of the independent patent claims.

Advantageous developments of the invention are characterized by the features stated in the subclaims.

In addition, when required extensive literature without cumbersome transport of a variety of conventional books can be carried on travel. The digital book is also particularly suitable as a reference work in places that do not offer great freedom of movement. Here the cockpit of a large commercial aircraft is particularly worth mentioning, in which a plurality of folders are typically carry with test and operation regulations. Particularly in emergency situations, it is important to question evidence quickly locate without time-consuming leaves.

A typical notebook o. Ä. Is only suitable for the more complicated handling and the vulnerability of its disk drive z. B. in turmoil. This is true in the rest to a large extent for use cases in private aircraft.

Another advantage is that at least two screens can be read as a whole pages in book format (portrait), wherein the at least two screens can fulfill distinct functions. So it is possible, for example, a full page to read a manuscript text and to be displayed simultaneously on the sub-screen of text excerpts that have been previously marked on the text page, or it can be different sides of the question (eg. As scientific) book text constitute mentioned with z. B. on the text page illustrations, without masking or wegzublenden the current book order. Also can be cross-references, etc. by Mark Nachschlagehinweise, for example by means of touch screen pen, show the source is given, "scroll" without.

The possibility of separating the screens of the digital book can be starting from a basic version of the same (which is intended only for reading) of the sub screen in accordance with the requirements and the prior art to the needs of the user to customize and thus the power spectrum of the digital book expand. For example, the off-screen to be designed to be pressure-sensitive, so a hand-written describing a screen is made possible by means of screen pin while the written text are quasi-simultaneously represented in block letters and possibly with the aid of a translation function of the software loaded in another language on the main screen can. This allows, for example, a faster and more convenient to create and edit business letters.
