Definitions

  • the invention relates to an input device of an electronic device according to the preamble of claim 1.
  • Portable electronic devices - in particular hand-held or even more miniaturized devices such as the so-called cell phone watch or the "wrist phone” - are increasingly performing complex functions and must therefore have sufficient input options.
  • hand-held telecommunication terminals cell phones and cordless telephones
  • handheld PCs or PDAs as well as combination devices
  • these include both the number and letter entry and, of course, the control of various functions.
  • a comfortable mobile phone offers an organizer, a (fee and nutrition) calculator, internet access, games, audio player, etc.
  • I&C Devices mobile devices of this type
  • the conventional hardkey solution - keys are used in various forms, which on the one hand and due to the abundance of functions due to the limited area of the end device, on the other hand, multiple assignments (e.g. as a 12-key keyboard with numbers and letters and possibly other functions). That means, depending on the context, pressing the button triggers a different action or function.
  • the various meanings of the respective key are conveyed here by appropriate multiple printing of the key, the basic problem being that the user has to find out or know which function is currently being called up by pressing a key, which is very unfavorable from an ergonomic point of view is.
  • the conventional softkey solution one or more keys are positioned as close as possible to the display.
  • the current meaning of the key is now shown in the display, which has the advantage that the user can clearly see what pressing the key in the respective situation.
  • the disadvantage is that the basic principle of such a softkey - i.e. the assignment of the display to the respective key - must be understood and in practice the assignment between key position and display label is often not optimal due to design restrictions, which leads to confusion and incorrect operation can.
  • the third concept - the touchscreen solution - uses a touch-sensitive display (touchscreen) that shows virtual keys with context-specific labeling that the user can then press or touch.
  • touch-sensitive display touchscreen
  • This very flexible solution has two main ones
  • the user has to press on a hard surface that does not offer any tactile feedback, which is ergonomically unfavorable.
  • the current implementation of touch sensitivity using a touch film applied to the display glass is relatively expensive and the film itself is also relatively sensitive to mechanical stress (eg scratches) and chemical effects (e.g. solvent) and temperature fluctuations.
  • the film deteriorates the optical quality of the display (brightness, contrast, sharpness, etc.).
  • keyboards offer better clarity and more direct and faster access to desired functions , especially for alphanumeric entries.
  • the use of the above electronic devices - e.g. B. a cell phone - is therefore still largely done via conventional buttons that make an electrical contact when pressed by a suitable electromechanical transducer.
  • the typical keyboard consists of (1) a metallic contact surface (eg a circuit board) and (2) individual keys or a key mat that is provided with an electrically conductive layer (eg graphite mixtures).
  • Such a constructive structure requires a certain minimum height and certain minimum distances around the individual contact surfaces for mechanical reasons.
  • limits are very quickly reached, which significantly restrict the number and possibilities of placing the keys.
  • Another problem is the limited design and design flexibility with conventionally constructed keyboards, which, for. B. strongly curved housing shapes, spherical surfaces, etc. in the operating area hardly or only with a very high design effort.
  • buttons Another limitation with conventional buttons concerns the potential contamination and corrosion of the contact surfaces by penetrating solid, liquid or gaseous particles.
  • a fourth limitation relates to the reduced, digital functionality of conventional keys, which generally only “knows” two states (on / off). Basically, such a mode of operation does not match differentiated "analog" control options and needs of humans.
  • the invention is therefore based on the object of specifying an input device of the generic type which is largely similar in the operation of conventional keyboards, but which is improved in the flexibility of the usability and the adaptability to miniaturized device concepts.
  • the invention includes the essential idea of a mechanical separation of the input sections, on which users press, from the actual converter areas - in which the recording or detection of the pressure and conversion into electrical signals take place. It further includes the idea of using pressure sensors known per se in an arrangement adapted to the specific operating requirements for realizing the converter areas. Finally, the invention includes the idea of providing a special sensor signal evaluation unit which is used to control the device. tes or signals used for data input clearly assigned to the user-recognizable and operated input sections.
  • Force-sensitive resistance elements are preferably used as pressure sensors or pressure-sensitive elements, which advantageously work analogously, ie. H. show a change in resistance which is dependent on the pressure force - in particular essentially proportional to it.
  • these resistance elements have two comb-like conductor track sections which are interlocked. Its outer contour is in particular approximately circular or elliptical, but can also be shaped differently. As a result of an elastic deformation, these FSRs advantageously give the user a tactile response, which leads to a significantly increased use value compared to conventional touchscreens.
  • the above-mentioned input sections are designed as input keys, ie as elements which are separate from the actual housing and are elastically displaceable relative to the latter.
  • the input sections are designed as pressure-elastic areas of an upper shell of the electronic device. Like the keys in the first embodiment, these are labeled with a function identifier, which identifier (in a known manner) can also have several functions or meanings of actuating the key or the housing area forming the input section.
  • the pressure sensors are shaped and arranged in association with the input sections, and the sensor signal evaluation unit is designed in such a way that the number of pressure sensors significantly exceeds the number of pressure sensors.
  • the evaluation unit is designed for the combined evaluation of analog signals from all pressure sensors in each input process according to an algorithm which evaluates the relations of the signal amplitudes of the pressure sensors that represent the respective input position.
  • the suitable algorithm for inserting the evaluation unit is determined empirically and / or on the basis of mathematical-geometric model calculations.
  • the sensor signal evaluation device (preferably regardless of the above-mentioned embodiment with combined evaluation of the signals of all pressure sensors to determine the position of an input) is preferably designed to evaluate analog signals of the pressure sensors. For this purpose, it enables the generation and output of pressure-dependent control signals, which in turn enables pressure-controlled input. This is particularly useful for specifying analog or quasi-analog device settings or functions - such as the pressure-controlled specification of a scroll
  • the preferred field of application of the proposed input device is hand-held electronic mass devices, such as, in particular, mobile radio terminals, cordless telephones, PDAs or handheld PCs or combination devices made from these. Basically, however, it can also be used with electronic devices for stationary or automotive use, such as audio or video devices and / or navigation devices etc.
