Definitions

  • the invention relates generally to obtaining user input for an electronic device. More specifically, the invention relates to obtaining user input with an opto-electronic arrangement.
  • One of the components having a large impact on the consumers' decision whether or not to buy a specific device is the input mechanism, such as the keyboard or dialling buttons of the mobile terminal.
  • Some manufacturers have mobile terminals which include a navigation key much like a joystick used in computers. Because the physical size of an average mobile terminal is very limited, the design of such devices is very challenging. The design gets even more challenging when such a device should reuse a maximal number of terminal components already existing, and still have an aesthetically acceptable outlook.
  • US patent 4,459,022 discloses a fibre optic angular sensor.
  • the sensor arrangement has long fibre cables and it is well suited for use in stationary equipment in areas with high electrical noise values.
  • the system comprises a concave mirror mounted on an object the orientation of which is to be measured.
  • the concave mirror is positioned over a fibre optic cable end which has the single light emitting central fibre end for receiving fibres.
  • a sensor disclosed in '022 due to its nature, is better suited to be used in stationary devices which are not so critical to the system size. For mobile terminals and similar small devices, nevertheless, the system the system disclosed in '022 is not suitable.
  • US patent 6,246,047 B1 discloses a fibre optic control with joystick.
  • the joystick has a pivot ball which has surface areas equipped with materials having different light reflecting properties.
  • the fibre optics has been realised in such a way that the system has two sets of fibre optic cable assemblies, each having a source of light and two cables for receiving the reflected light rays.
  • the pivot ball In the pivot ball there are large surface portions of poor light reflecting properties and other surface portions of good light reflecting properties.
  • a light beam is directed against various portions of the ball surface. Reflections of light from said surfaces provide output light signals which are a function of the vertical position of the ball as effected by the movements of the joystick.
  • the pivot ball has been adapted to measure the angular position of the joystick. Because angular movements usually do not suffice to fulfil the requirements set forth in the typical applications used in mobile terminals, wherein the user is expected to press or tilt a button, or to turn a joystick-like input device, the '047 approach is not considered to be a solution for the problem in hand.
  • WO 91/20022 discloses a joystick assembly for connection to a computer, including a control arm coupled to a pair of shutters which are moved independently in accordance with the direction and degree of movement of the control arm.
  • a light emitter and light sensor are arranged on opposite sides of each shutter and the light received by the light sensor varies in accordance with the degree to which the shutters block the path of light between emitter and light sensor.
  • the variable outputs provided by the light sensors are used to control movement of an image on a video display unit.
  • Another objective of the invention is to bring about a new input method, possibly even reusing some existing hardware components.
  • FIG. 1 illustrates an input device, of which the principles of detecting user input are found in prior art.
  • a light source 100 such as a light emitting diode LED emits a total light flux F.
  • Parts FA, FB of this total flux F are led to light directing means 1031, 1032 which can, for example, be a wave guide, optical fibre, transparent plastic, or just a hollow space left in the device.
  • modulation means 104A, 104B which are ready to modulate the light flux FA, FB to a modulated light flux FA', FB' respectively.
  • the modulation means 104A, 104B are responsive to a pointing device 104 which can be a navigation key, joystick, or other similar arrangement for receiving a user input.
  • the modulated light flux FA', FB' can be detected by detecting means 106A, 106B.
  • the detecting means 106A, 106B can, for example, be light sensors including a resistor, the resistance of which changes when the detected strength of the modulated light flux FA', FB' changes.
  • the detecting means 106A, 106B generate a signal SA, SB that is passed to converting means 110 which generates an input signal IS from the generated signal SA, SB.
  • the input signal IS is responsive to one or more of the modulated light fluxes FA', FB', and because the modulated light fluxes FA', FB' are responsive to the position of the modulating means 104A, 104B further being responsive to the position of the pointing device 104, the position of the pointing device 104 may be monitored by observing the values of the input signal IS.
  • the detecting means 106A, 106B are preferably assembled to measure the modulated light flux FA', FB' in the light path at point where a part FA, FB of the light flux would pass in order to achieve constructional simplicity. This can be accomplished e.g. by positioning the detecting means 106A, 106B in line with the light directing means (1031, 1032), the positioning then corresponding to the path of an part FA, FB of the light flux F, i.e. the path of the photons which they would take in the absence of the modulating means 104A, 104B.
  • the detecting means 106A, 106B are located substantially at a continuation of a path of the modulated light flux FA', FB', respectively, in absence of the user input.
  • the modulation means 104A, 104B are preferably located on a straight line between the light directing means 1031, 1032 and detecting means 106A, 106B.
  • the system includes a housing 130, such as a housing used in mobile station.
  • Shielding means 120 are preferably of elastic material, such as rubber or silicon, and they are adapted to elastically seal the space between the housing 130, the modulation means 104A, 104B, and the pointing device 104.
  • Figure 2 illustrates the input device presented above with reference to Figure 1 in a second position.
  • the differences caused by moving the pointing device 104 to a second position are that the parts FA, FB of the light flux F are modulated now in a different way.
  • the part FA becomes the modulated light flux FA' in such a way that most of the light rays can not get through the modulation means 104A, whereas the part FB is in principle not modified at all by the modulation means 104B so that the modulated light flux FB' corresponds almost in its entirety to the part FB of the light flux F.
  • the sealing means 120 on the side of modulation means 104A are compressed whereas the sealing means 120 on the other side of the pointing means are elongated.
  • the tilting of the pointing device causes a rotational motion to the pointing device 104 and thus the modulation means 104A, 104B rotate round a symmetric axis.
  • this rotational movement can be characterised by vertical movement, that is, the modulation means 104A move downwards and modulate by shadowing the part FA of the light flux F to a modulated light flux FA'.
  • the modulation means 104B move upwards thus clearing the passage of the light flux FB; i.e. the modulated light flux FB' corresponds to the light flux FB.
  • the modulated light fluxes FA', FB' are different when the pointing device is in the second position, also the modulated light fluxes FA', FB' detected by the detecting means 106A, 106B are different, which then has an impact on the generated signals SA, SB.
  • the light flux F can be divided into parts of light fluxes FA, FB by using a beam splitter, for example.
  • the beam splitter can also be a thin layer of metallic coating on a part of the transparent end of the light directing means. Using such a solution the manufacturing costs can be reduced and the device can be build using less components.
  • Figure 3 represents a first embodiment of an input device according to the invention.
  • the light source 100 is located at a different position from the embodiment according to Figure 1.
  • the light source 100 can be, as before, a LED or some other light source producing the light flux F.
  • the light source 100 in mobile stations, there are light sources such as LEDs widely used in the vicinity of the keyboard for lightening it, and, correspondingly, around the display for giving the display back light. This already existing light source 100 may thus be reused, and at least part of the light flux F emitted by the light source 100 is led to light directing means 103.
  • the light directing means 103 may be similar to the light directing means 1031, 1032, i.e. they consist of simple fibres, shallow space, or something corresponding.
  • the light directing means 103 lead at least part of the light flux F to a beam splitter 108.
  • the beam splitter 108 divides a light flux to parts FA, FB of the light flux F.
  • the advantage gained by using the beam splitter 108 in combination with the remotely placed light source 100 is that the system can be implemented using an already existing light source thus reducing the number of components needed. For mobile terminals this is important in the sense that the reliability of the device is enhanced, because the number of components having only a reduced life time is minimised.
  • the beam splitter 108 can be a mirror like element, such as a clear pyramid or tetrahedron shaped polished piece of metal.
  • the modulation step is performed in a nonreflective manner such as by filtering the light flux with an opaque filter or with a filter that has polarisation characteristics.
  • a nonreflective manner such as by filtering the light flux with an opaque filter or with a filter that has polarisation characteristics.
  • One of the purposes is to keep the physical size of the device as small as possible, another of the purposes is to keep also the fluxes needed as small as possible, because of energy considerations i.e. saving the power supply of the mobile device wherein the input device is used, and because it is more challenging to obtain good reflective properties for the beam splitter and for the modulator.
  • Figure 4 illustrates some aspects of the fastening mechanism of the pointing device 104.
  • the system comprises a number of springs 401, 402 that are placed between the pointing device 104 and the bottom 400.
  • the bottom 400 may be, for example, a part of the circuit board located in the device wherein the input device is to be assembled, or it may be also be supported to light directing means 1031, 1032.
  • the springs 401, 402 are arranged to allow tilting or small movement of the pointing device 104 in such a way that if the pointing device 104 is pressed down at one point, it allows the movement of modulation means 104A, 104B.
  • the bottom part of the joystick preferably has a flat board like member wherein the modulation means 104A, 104B are collected. The movement of this board like member causes a compressing force on the spring 401 and an extending force on the spring 402, for example.
  • FIG. 5 illustrates the input device as viewed from top.
  • the pointing device 104 preferably includes an opaque part 510 of the surface and a transparent part 511 of the surface. If there is some illumination under the pointing device 104 coming from the light source 100, the transparent part 511 of the surface is thereby illuminated. This assists the user for giving the user input, especially in bad light conditions. Further, it gives the input device 104 a very fashionable look and thereby increases the attractivity of the mobile terminal wherein input device 104 is installed.
  • the transparent part 511 may include trademarks or product names 512, and additional information 514 such as directions or input symbols. Such printings may printed on the surface provided that the area of the surface is large enough. This kind of approach increases the comfort of use, because the device is easy to handle also in the dark or under bad light conditions.
  • Figure 6 illustrates the input device 104 as seen from below.
  • a plurality of springs 401, 402, 403 and 404 are placed on the bottom surface of the pointing device and fastened there.
  • the modulation means 104A and 104B shown are adapted to modulate the light fluxes coming from the light directing means 1031 and 1032.
  • detectors 106A, 106B there are also detectors 106A, 106B.
  • the detecting means 106A, 106B detect the modulated light flux.
  • the input device 104 may have a plurality of degrees of freedom.
  • the number of light directing means 1031-1034, modulation means 106A-D and detecting means 106A-D may change.
  • the light directing means 1033, 1034 are optional and therefore marked with a dotted line.
  • the optional detectors 106C and 106D are marked with a dotted line.
  • the optional modulation means 104C and 104D modulate parts of the light flux F that are going to be detected by the optional detecting means 106C, 106D.
  • the number of degrees of freedom may vary, for example, values between 1 and 8 being the most useful degrees of freedom for two-dimensional movements, as more directions are hard for the user to point accurately using the input device 104.
  • the positioning of the spring elements 401 to 404 should be reconsidered similarly as the positioning of the light directing means 106A to 106D.
  • the calibration of the pointing device 104 can be performed by comparing the modulated light flux (FA', FB') at different positions of the pointing device 104, i.e. by comparing the signal SA, SB derived from the detecting means 106A, 106B or the input signal IS, with the position of the pointing device 104.
  • the pointing device 104 possesses multiple positions in one direction.
  • the angle of tilting of the pointing device causes a movement in the modulator 104A - 104D.
  • the converting means 110 have a table with different threshold values for each position of the pointing device 104, corresponding to the signal SA - SD, thus producing a different input signal IS.
  • This kind of approach enables reliable detection of the position of the user input having only few positions. No complex nor expensive components in measuring the fluxes are needed either.
  • the speed of movement of the pointing device 104 may also be measured by the converting means 110. This corresponds to time deviation of the generated signals SA - SD. If the time rate of change of the signals SA - SD for each signal is below a first threshold value, the position of the pointing device 104 is not moving. On the other hand, if the speed of change of the signals SA - SD exceeds the first threshold value, then the speed of change of the signal SA - SD may further be subdivided to correspond slow, medium, and fast changes, and so forth.
  • the converting means 110 preferably include this information into the input signal IS.
  • the invention is not limited to these examples, but also the movement pattern of the pointing device 104, acceleration, direction and intensity of the pointing device 104 may be measured; again an input signal IS is produced.
  • the input signal IS is responsive to the movement.
  • the input signal IS further guides the operation of the light source 100.
  • This may be implemented by using a control circuit reading the input signal IS. If the input signal corresponds to a valid user input, i.e. the pointing device 104 is in a position or has been moved accordingly, the control circuit may either switch off the power of the light source, increase it, change colour of the light source, or give a control signal to a voice circuit that makes a small tick or other sound thus informing the user that his/her input has already been registered.
  • An advantageous possibility for fixing the pointing device 104 is to use a ring-shape gasket made of an elastic material, such as rubber.
  • the springs 401 - 404 can then be installed into the rubber gasket in order to ensure a proper mechanism for guiding the movements of the pointing device 104.
  • Figure 7 illustrates how light directing means 1031 and 1032 may be made movable, i.e. they can be directly fixed to the pointing device 104.
  • the pointing device 104 acts as a modulator by moving the light directing means 1031, 1032.
  • the light directing means 1031, 1032 move together with the body of the pointing device 104, the number of photons missing the detecting means 106A, 106B changes.
  • the detecting means 106A, 106B are substantially located at a continuation of a path of the modulated light flux FA' FB', respectively, in absence of the user input.
  • the modulation achieved depends on the position of the light directing means 1031, 1032 compared to the position of the detecting means 106A, 106B.
  • the modulation means 104A, 104B are preferably located on a straight line between light directing means 1031, 1032 and detecting means 106A, 106B.
  • the sealing means 120 may now include spring elements or some other suitable elastic material in order to get a returning force which returns the pointing device 104 into its initial position after the user has released the pointing device 104.
  • springs 402 are installed in order to support the pointing device 402 and the light directing means 103.
  • Stopper 778 limits the maximum deviation of the pointing device 104 and the light directing means 103 from the normal position, i.e. maximum sideward movement.
  • Another stopper 777 may be installed at the bottom of light directing means 103.
  • a possibility for splitting the flux F to the parts FA and FB of the flux F is to use a beam splitter 108 directly installed to the pointing device 104.
  • This can be realised e.g. by spraying a thin metallic layer onto either surfaces of the pointing device 104, i.e. between the light directing means 1031, 1032 and the transparent middle part 511 of the pointing device 104.
  • This causes reflections which optically connect to wave-guides 1031 - 1034 thus forming the fluxes FA, FB to be modified by the modulator 104A - 104D.
  • the cost of the phone can be reduced because no separate beam splitter 100 is needed but this may be implemented using the pointing device 104.
  • Figure 8 illustrates the light directing means as viewed from above when the pointing device 104 has been removed.
  • the thin metallic layer referenced above may be sprayed on the light directing means 1031-1034, and the light directing means 103 as well.
  • Figure 9 shows the input device according to the present invention installed as one of its most obvious applications. Even though the input device may be used in any portable device, such as a Personal Digital Assistant, portable computer, and so forth, one of the most practical targets is a mobile terminal 900, such as a GSM or an UMTS phone. In this kind of device the size, power consumption and design matters play a significant role.
