Description

Handheld device for data input as well as remote control device, mobile telephone and gaming device

The invention relates to a handheld device for data input as well as a remote control device, a mobile telephone and a gaming device, wherein the remote control device, the mobile telephone and the gaming device comprise the handheld device .

Mobile electronic handheld devices for data input are known for various applications . A mobile telephone comprises for example a keyboard or a touch screen with which telephone numbers, messages or data recordings can be input into the mobile telephone . A remote control device for for example a TV set or a stereo comprises various program and function keys that are built in the remote control device as push buttons or membrane keys . It is required for the handheld devices that they are as small as possible, handy and comfortably operatable . However, it is problematic that handheld devices with a sma11 size are handy in the placement , but difficult in the operation and in the manual handling . Furthermore, it is desirable that the handheld devices are shaped ergonomically for the human hand, wherein the motility of the fingers and the thumb has to be taken into account . However, when often and fast operating the handheld device it can lead to tensions in the hand, in the arm and in the neck of the operator . These tensions can affect the motility and cause pain, whereby an indisposition and even a handicap of the operator can be caused . Besides the physical health also the psyche of the operator can thereby be affected, whereby decisions of the operator during the operation of the handheld device can potentially be influenced.

It is an obj ect of the invention to provide a handheld device for data input as well as a remote control device, a mobile telephone and a gaming device , wherein the remote control device, the mobile telephone and gaming device comprise the handheld device, wherein a fast and comfortable data input is enabled with the devices during which the person operating the handheld device is relaxed and feels good. The handheld device according to the invention for data input comprises a data processing unit and a casing that is shaped adapted to a hand for holding in the hand ergonomically in the manner of a palm stone as well as at least one input key that is coupled with the data processing unit for processing of the data input by the input key and arranged on the casing such that, when the handheld device is held in the hand, the input key can be pressed for the data input by at least one of the four fingers or the thumb of the hand and a compressive force can thereby be transferred from the finger or the thumb from the handheld device to the palm of the hand, wherein a surface location of the casing, which is arranged facing away from the input key and, when the handheld device is held in the hand, at least one of the reflection zones of the palm is arranged directly adj acent to the surface location, wherein the casing is provided with at least one stimulation protrusion protruding from the surface location, so that nerve end points of the reflection zone can be stimulated via the stimulation

protrusion by pressing the input key, whereby the part of the body assigned to the reflection zone is stimulated during the data input .

Reflection zones that are for example assigned to the solar plexus , the stomach, the liver or the lung are arranged on the palm. Reflection zones that are assigned to the frontal sinuses and the head cavities are arranged on the finger domes and a reflection zone that is assigned to the brain is located on the thumb dome . If the nerve end points of the reflection zones are stimulated during the data input , a pleasant and relaxing effect on the according assigned parts of the body is caused, namely on the solar plexus, in the stomach, in the frontal sinuses and in the head cavities, in the brain, in the liver and in the lung . Therefore, the well-being of the person that performs the data input with the handheld device according to the invention is increased during the data input and beyond . The increasing of the well-being leads to an improvement of the health and the psychic state of the person. Caused by the well- being of the person caused by the data input by means of the handheld device, the person can be inspired to ar-reaching thoughts and ideas that can have a positive effect on the manner and the quality of the data input.

If the person suffers for example from nervousness that effects its stomach, the data input with the handheld device can cause a sedation of the stomach, if the reflection zones for the stomach and the solar plexus are stimulated with the

stimulation protrusion . The person becomes calmer and feels freer after the data input with the handheld device . Thereby, the person could be guided to creative ideas .

The casing comprises preferably at least one orientation knob assigned to one of the roots of the fingers , wherein, when the handheld device is held in the hand, the orientation knob is in engagement with its assigned root and the stimulation

protrusion can be brought in touch contact with its assigned reflection zone and the input key can be pressed by its

assigned finger/thumb .

The orientation knob is easily brought in engagement with the root of the finger assigned to the orientation knob, when the handheld device is held in the hand in the manner of a palm stone . The arrangements of the input key relative to the fingers respectively the thumb and of the stimulation

protrusion relative to the reflection zone are thereby fixed. The positionings of the input key relative to the fingers and the stimulation protrusion relative to the reflection zone can therefore be reproduced, whereby the handling of the handheld device is made easier .

It is preferred that the input key can be pressed by the finger dome/thumb dome of the finger/thumb assigned to the input key. The according reflection zone is stimulated during pressing of the input key with the respective finger dome/thumb dome as a result of the reflection zones for the frontal sinuses and the head cavities being located on the finger domes and the

reflection zone of the brain being located on the thumb dome .

The casing comprises preferably a casing opening in the surface location and the handheld device comprises a displaceable supported propagation bolt coupled with the input key that, when the input key is pressed, the propagation bolt extends through the casing opening with its one longitudinal end and protrudes from the surface location, whereby the longitudinal end forms the stimulation protrusion . The propagation bolt displaces out of the casing opening and protrudes with its one longitudinal end from the casing of the handheld device during pressing of the input key . A particular intensive stimulation of the reflection zone assigned to the propagation bolt is thereby carried out in particular during pressing of the input key so that a strong stimulation of the part of the body assigned to the reflection zone is enabled by means of the propagation bolt . It is furthermore preferred that the stimulation of the

reflection zone assigned to the propagation bolt can be

adjusted by the form of the longitudina L end of the propagation bolt and the magnitude of the driving of the propagation bolt out of the cas ing opening . If, for example, the one

longitudinal, end of the propagation bolt is formed as a tip and the propagation bolt is driven out comparat ively long during pressing of the input key so that the one longitudinal end protrudes with a comparatively large distance from the casing of the handheld device, a comparatively strong stimulation of the reflection zone assigned to the propagation bolt is achieved .

It is further preferred that the propagation bolt has such dimensions , is supported such and is coupled with the input key such that , when the input key is not pressed, the longitudinal end of the propagation bolt is countersunk in the casing ope ing . Therefore, an explicit stimula ion of the reflection zone assigned to the propagation bolt is not provided when the input key is unpressed . The stimulation of the reflection zone assigned to the propagation bo Lt is felt all the more stronger if the input key is pressed and the propagation bolt drives out of the casing opening and stimulates the reflection zone

assigned to the propagation bolt . The stimulation is effective and it is prevented that a familiarization to the stimulation is caused by the strong change of the stimulation of the reflection zone assigned to the propagation bolt by pressing and unpressing of the input key.

The input key comprises preferably a displaceable key head for pressing of the input key, wherein the key head is fixed on the propagation bolt and extends the propagation bolt so that the key head completely penetrates the casing together with the propagation bolt . The pressing movement of the finger assigned to the input key is thereby directly transferred to the

reflection zone assigned to the propagation bolt .

Alternatively, it is preferred that a transmission gearing, for example in the shape of a pivo mounted lever with different long arms , is interconnected between the propagation bolt and the input key, whereby the stroke of the input key can be translated to the stroke of the propagation bolt . A

compa atively small stroke of the input key can thereby be translated to a comparatively long stroke of the propagation bolt .

The key head comprises preferably a stimulation tip that protrudes from the cas ing, whereby the finger/thumb is

stimulated d ring pressing of the input key . A strong

stimulation of the reflection zone on the finger dome/thumb dome therefore occurs . Alternat ively, it is preferred that the input key comprises a displaceable key head for pressing of the input key and the propagation bolt completely penetrates the casing as well as extends in the key head, so that , when the input key is pressed, the longitudinal end of the propagation bolt , which is arranged facing away from the casing opening, extends through a key head opening of the key head and

protrudes from the key head, whereby the finger/thumb is stimulated during pressing of the input key. The other

longitudinal end of the propagation bolt thereby drives out of the key head opening and protrudes from the key head during pressing of the input key. The propagation bolt is therefore supported from both the finger/thumb and the palm, whereby a strong stimulation of the affected reflection zones is

achieved . It is furthermore preferred that the propagation bolt can be displaced into each other in the manner of a telescope under overcoming a resistance force , whereby the intensity of the stimulation of the affected reflecting zones can be

adj usted by the strength of the resistance force .

The handheld device furthermore comprises preferably a

pretension means that grabs the key head and drives the key head in its unpressed position with its pretension force being directed against the compressive force, wherein the pretension means has such dimensions that the pretension force leads to such a strength of the compressive force that the part of the body assigned to the reflection zone is stimulated for a relaxation, a pain relief or an illness healing during the data input . Therefore, the dimensioning of the pretension means is used in order to generate an individually chosen stimulation for each affected reflection zone . The stimulation can

f rthermore be adjusted indi idual-related by the according dimensioning of the pretension means . If, for example , the pretension force is comparatively strong, the stimulation on the finger dome/thumb dome is comparatively small, whereas the stimulation on the palm is comparatively strong . A strong stimulation is generated on the finger dome/thumb dome if the pretension force is comparatively small , wherein the

stimulation on the palm results in dependence from the

compressive force .

The propagation bolt is preferably formed arcuately . It is furthermore preferred that the propagation bolt can be bend.

The propagation bolt is preferably longitudinally directed in a guiding channel in the casing so that, since the propagation bolt is formed arcuately, a constructional simple bridging of the housing by the propagation bolt is enabled.

It is preferred that the handheld device comprises a respective input key for each of the four fingers and an additional input key for the thumb, wherein the additional input key is formed as a multifunction key with which different functionalities of the input keys for the fingers can be switched . If, for

example, the multifunction key can be switched to seven

switching levels, a maximum of 28 different signs can be represented with the four function keys . For example, the alphabet could thereby be represented with the four function keys and the multifunction key. The data processing unit comprises preferably a memory with which the data being input by the input keys can be stored. If the alphabet is represented with the four input keys and the multi unction key, the handheld device can be used for a text input . A letter from the alphabet can be input and stored in the memory by accordingly choosing one of the seven switch levels of the multifunct ion key and the combined pressing of a suitable of the four input keys . If the person holds the handheld device in the hand and the hand is for example stuck in a trouser pocket, the text input can be carried out

inconspicuously with the handheld device . The memory can for example be read out by a computer at a later point in time and possible at another location, whereby the text generated during the text input is made available . The handheld device according to the invention is a remote control device for remote controlling of an apparatus, a mobile telephone or a gaming device . The therapeutic effect by the hand reflection zone massage of the handheld device during the data input unfolds according to the invention d ing the handling of the remote control device, the mobile telephone and the gaming device . Other applications of the handheld device for data input are conceivable . In the following preferred embodiments of the handheld device according to the invention are explained on the basis of the schematic drawings . It shows : Figure 1 a perspective representation of a first embodiment of the handheld device that is held in a right hand,

Figure 4 a sectional representation of a third embodiment of the handheld device and

Figure 5 a right hand with markings of reflection zones .

Figure 5 shows the top view of the inner side of a human right hand 101. The hand 101 comprises a thumb 102 , an index finger

103, a middle finger 10 , a ring finger 105 and a little finger 106. The fingers 103 to 106 comprise a respective fingertip 107 on its respective f ee longitudinal ends , wherein the fingers 103 to 106 are articulated on the hand 101 with a respective finger root 108 on the palm 111. A respective finger dome 110 is arranged on the fingertips 107 , whereas the thumb 102 comprises a thumb dome 109.

Respective reflection zones 114 for frontal sinuses and head cavities are arranged on the finger domes 110. A ref lection zone 116 for the liver is arranged on the palm 111 in the area of the little finger 106, a reflection zone 117 for the lung and a reflection zone 112 for the solar plexus are arranged on the palm 111 in the area of the middle finger 104 and the ring finger 105 and a reflection zone 113 for the stomach is arranged on the palm in the area of the index finger 103. As it can be seen from Figs. 1 to 4 a handheld device 1

comprises a casing 2 that comprises and input key 3 for the thumb 102, an input key 4 for the index finger 103 , an input key 4 for the middle finger 104 , an input key 6 for the ring finger 105 and an input key 7 for the little finger 106. The handheld device 1 furthermore comprises an orientation knob 8 for the root of the index finger 103, an orientation knob 9 for the root of the middle finger 104 , an orientation knob 10 for the root of the ring finger 105 and an orientation knob 11 for the root of the little finger 106. The handheld device 1 furthermore comprises a stimulation protrusion 12 for the reflection zone 112 of the solar plexus , a stimulation

protrusion 13 for the reflection zone 113 for the stomach, a stimulation protrusion 14 for the reflection zone 116 for the liver and a stimulation protrusion 15 for the reflection zone 117 for the lung .

The input keys 3 to 7 are formed as push buttons . he

orientation knobs 8 to 11 and the stimulation protrusions 12 to 15 are shaped as fixed protrusions protruding from the casing

2. The casing 2 is formed for holding ergonomically in the hand 101 in the manner of a palm stone and has about the size of a chicken egg . The orientation knobs 8 to 11 are in an engagement with the hand 101 with its respective finger roots 108 during holding the handheld device 1 in the hand 101, so that the handheld device 1 can be gripped by the hand 101 with its fingers 102 to 106 and the palm 111. The input keys 3 to 7 are arranged on the casing 2 relative to the orientation knobs 8 to 11 such that the input keys 3 to 7 can be comfortably pressed by the fingers 103 to 106 respectively by the humb 102 assigned to the input keys 3 to 7 with its respective finger domes 110 respectively the thumb dome 109. The stimulation protrusions 12 to 15 are arranged on the casing 2 relative to the orientation knobs 8 to 11 such that when the handheld device 1 is held in the hand 101, the stimulation protrusion 12 touches the reflexion zone 112 for the solar plexus, the st imulat ion protrusion 13 touches the reflection zone 113 for the stomach, the stimulation protrusion 14 touches the reflection zone 114 for the liver and the stimulation protrusion 15 touches the reflection zone 115 for the lung .

In Figures 1 and 2 a first embodiment of the handheld device 1 is shown, wherein the stimulation protrusions 12 to 15 are shaped as local elevations on the casing 2. The input keys 3 to 7 are formed as push buttons .

In Figure 3 a second embodiment of the handheld device 1 is shown . The design of the input keys 3 to 7 is exemplified for the input key 6 for the ring finger 105. The input key 6 comprises a key head 16 that is formed in the manner of a cylinder and is supported such that it can be displaced

longitudinally in an according directing shaft 17 in the casing 2. The directing shaft 17 is oriented in the casing 2 such that , when the key head 16 is pressed by the ring finger 105, the key head 16 is displaced longitudinally in the direct ion shaft 17. The key head 16 is accessible from outside the casing 2 by the ring finger 105 by the key head 16 with its one longitudinal end protrudin out of the directing shaft 17 and therefore protruding from the casing 2. A stimulation tip 18 is provided at the outer end of the key head 16, wherein the stimulation tip 18 is touched by the finger dome 110 of the ring finger 105 during pressing of the input key 6. The

reflection zone 114 for the frontal sinuses and the head cavities on the ring finger 105 is therefore stimulated . A propagation bolt 19 is fixed on the longitudinal end of the key head 16, wherein the longitudinal e d is facing away from the stimulation tip 17 and the propagation bolt 19 is aligned with the key head 16 and extends to a casing opening 21 of the casing 2 , wherein the key head 16 completely penetrates the casing 2 together with the propagation bolt 19. Because the key head 16 has a larger diameter than the propagation bolt 19 a step 20 is formed at the t ansition from the key head 16 to the propagation bolt 19. The propagation bolt 19 extends in particular in the pressed state of the input key 6 with its longitudinal end 22 that is facing away from the key head 16 through the casing opening 21. This longitudinal end 22 protrudes from the casing 2 and forms the stimulation protrusion 16 for the reflection zone 115 for the lung . The casing opening 21 is formed in a perforated disc 23 that is arranged concentric around the propagation bolt 19 in the casing 2. Therefore, the perforated disc 23 corresponds with the step 20, wherein a first return spring 24 is supported on the step 20 and on the perforated disc 23 and is arranged around the propagat ion bolt 19. The spring force of the return spring 24 is directed against the compressive force during pressing the input key 6.

The finger dome 110 of the ring finger 105 touches the

stimulation tip 18 d ri g pressing the input key 6 with the ring finger 105. The key head 16 together with the propagation bolt 19 displaces in the directing shaft 17 by overcoming of the spring force of the return spring 24, so that the key head 16 is gradually countersunk in the directing shaft 17 and the longitudinal end 22 facing away the key head 16 of the

propagation bolt 19 gradually protrudes out of the casing opening 21. A counterforce acts from the palm 111 to the propagation bolt 19 and the key head 16, wherein the

counterforce is directed against the compressive force from the ring finger 105 , since the longitudinal end 22 presses on the palm 111 and thereby on the reflection zone 117 for the lung. Therefore, the force with which the longitudinal end 22 of the propagation bolt 19 presses on the reflection zone 117 for the lung results from the compressive force generated from the ring finger 105 to the stimulation tip 18 reduced by the return force of the return spring 24. A stimulation of the affected reflection zones 114 and 117 results therefrom, wherein the stimulation of the assigned parts of the body is such that a relaxation, a pain relief or a illness healing can be caused . In Figure 4 a third embodiment of the handheld device 1 is shown, wherein exemplary the design of the input key 4 for the index finger 103 is shown. According to this embodiment the casing 2 comprises a bolt channel 25 in which the propagation bolt 19 is supported displaceable longitudinally, wherein the propagation bolt 19 extends completely through the casing 2. The one longitudinal end 22 of the propagation bolt 19

protrudes through the casing opening 21 when the input key 4 is pressed in order to act as the stimulation protrusion 13 for the reflexion zone 113 for the stomach .

The key head 16 is arranged concentrically around the

propagation bolt 19, wherein the key head 16 comprises a key head cap 26 facing away from the casing 2. A key head opening 27 is provided in the key head cap 26, wherein the other longitudinal end of the propagation bolt 19 can extend through the key head opening 27 , wherein the other longitudinal end is facing away from the casing opening . As a result of the key head 17 being located, in the directing shaft 17 , the key head 16 having a larger diameter than the propagation bolt 19 and the propagation bolt 19 being located in the bolt channel 25, the transition from the bolt channel 25 to the directing shaft 17 is shaped in a step-like manner, whereby a ground 29 is present . A second return spring 30 is supported on the base 29 and on the inner face of the key head cap 26 so that a return force from the return spring 30 in an unpressed state of the input key 4 is acting on the key head 16.

The key head 16 and the propagation bolt 19 can be displaced freely to each other . The key head 16 is displaced into the directing shaft 17 during pressing of the input key 4 with the finger dome 110 of the index finger 103, wherein the

propagation bolt 19 with its longitudinal end 28 extends through the key head opening 27 and protrudes from the key head cap 26. Therefore , the reflection zone 114 on the finger dome 110 of the index finger 103 is stimulated. As result of the pressing of the longitudinal end 28 of the propagation bolt 19 with the finger dome 110 of the index finger 103, the propagation bolt 19 displaces in the bolt channel 25, so that the other longitudinal end 22 of the propagation bolt 19 is gradually driven out of the casing opening 21 and the

reflection zone 113 for the stomach is stimulated . The

magnitude of the stimulation of the reflection zone 114 on the finger dome and the reflection zone 113 on the palm 111 can be adj usted in dependence on the characte istic line of the return spring 30, the length of the protrusions of the propagation bolt 19 on its longitudinal ends 22 and 28 as well as the friction between the propagation bolt 19 and the bolt channel 25 and/or the key head 16 and the directing shaft 17.

The described embodiments of the input keys 3 to 7 and other embodiments in the handheld device 1 are conceivable as

arbitrary combinations .

The input keys 3 to 7 are interconnected with a data processing unit 32 via signal lines 31 in each of the embodiments of the handheld device 1. The data being input by the input keys 3 to 7 are processed by means of the data processing unit 32. For this reason the data processing unit 32 comprises an input unit 32 , with which the data input is controlled, and a memory 34, with which the input data is stored. For the operation of the data processing unit 32 the data processing u it 32 comprises a battery 35 for the power supply. Furthermore, the data

processing unit 32 comprises an output unit 36, with which the data stored in the memory 34 can be read out via an output connection 37 to external devices . The input key 3 is formed as a multifunction key, with which seven positions can be switched with the thumb 102. The input unit 32 is adapted such that groups of letters of the alphabet can be assigned to the input keys 4 to 7 in dependence on the respective position of the input key 3. In such a configuration the handheld device 1 serves as a text input device , wherein texts can be input with the fingers 103 to 106 with the input keys 4 to 7 according the actuation of the input key with the thumb 102 , wherein the text can be stored in the memory unit 34 and can be read out with the output unit 36 via the output connection 37. The output unit 36 can furthermore comprise a WLAN-module for outputting the data, wherein the data can be read out with the WLAN-module via internet .

It is also conceivable that the handheld device 1 with its arrangement of the input keys 3 to 7 is designed symmetrically such that the handheld device 1 can be operated with both hands under the stimulation of the relevant reflection zones 112 to 117 , whereby the handheld device 1 can be applied with both hands , consequently the handheld device 1 can be held and be operated equivalently both from the right hand and from the left hand and therefore the handheld device 1 is suitable both for a right-hander for a left-hander .
