FIELD OF THE INVENTION
The present invention generally relates to a control mechanism and more particularly to a control mechanism having an image display area.
BACKGROUND OF THE INVENTION
Hardware control mechanisms, such as for example, including but not limited to control knobs and control buttons are routinely used as input mechanisms for providing input data to different types of systems and to enable user interaction with said systems. Moving hardware controls typically provide valuable tactile feedback to the user. When a user wishes to provide an input to a system, the user typically manipulates the position of the associated hardware control mechanism to provide a desired input to the system. For example, a user may rotate a control knob to provide a desire input. In another example, a hardware control mechanism may include a plurality of control push buttons where each individual button is associated with a different input and a user selectively actuates the control button associated with the input that the user wishes to provide to the system.
As system complexities and capabilities increase, mechanisms for providing complex visual feedback at or near the control mechanism may be desirable. Examples of such visual feedback mechanisms include, but are not limited to, task icons, mode dependent menus or level controls and animated graphic schematics of the system operation affected by the control mechanism.
SUMMARY OF THE INVENTION
On aspect of the invention is directed to a control mechanism having an image display area. The control mechanism includes a housing, an input sensor, a display screen and an optical coupling system. The housing includes a display area and is moveable from a first position to a second position. The input sensor is operable to detect movement of the housing and to be communicatively coupled to a controller. The display screen is operable to be communicatively coupled to the controller and to display a first image generated by the controller responsive to detection of movement of the housing from the first position to the second position by the input sensor. The optical coupling system is operable to optically couple an area of the display screen to the display area of the housing and to optically transmit at least a portion of the first image displayed on the display screen for display in the display area.

In one embodiment, the optical coupling system 308 is a rear projection system. In one embodiment, the optical coupling system 308 is a fiber optic system. In one embodiment, the optical coupling system 308 is a material composed of parallel packed optical fibers. While a number of different types of optical coupling systems 308 have been described alternative types of optical coupling systems 308 may be used to transmit at least a portion of an image displayed on an area of a display screen 306 to a display area 106 of a housing 302.
In one embodiment, the housing 302 is manufactured using a fiber optic material and operates as the optical coupling system 308. At least a portion of the surface of the housing 302 operates as the display area 106. Such a housing 302 is positioned adjacent to the display screen 306 such that at least a portion of an image displayed on the display screen 306 is piped to the display area 106 portion of the housing 302. In one embodiment, one or more images are displayed on the display screen 306 in a first orientation. At least a portion of the one or more images is displayed in the display area 106 in the first orientation.
The housing 302 is moveable between one or more different housing positions. In one embodiment, the housing 302 is moveable independent of and relative to the display screen 306. In one embodiment, the housing 302 is moveable independent of and relative to the optical coupling system 308. Each of the one or more different housing positions is associated with specific input data. In one embodiment, when a user wishes to provide selected input data to the controlled system 104 via the control mechanism 102, the user moves the housing 302 to a housing position associated with the selected input data. In one embodiment, the housing 302 is biased towards an initial position so upon releasing the housing 302 following the selective movement of the housing 302 to a position associated with the desired input data, the housing 302 automatically returns to the initial position.
The input sensor 304 senses the movement of the housing 302 and communicates the sensed housing movement to the controlled mechanism 104 via the communication module 310. In one embodiment, the sensed housing movement is a sensed rate of movement of the housing 302. The controlled mechanism 104 receives the housing movement detected by the input sensor 304 and determines whether the housing movement data is associated with specific input data and responsively generates an image generation command to generate one or more images associated with the determined input data for display on the display screen 306.
In one embodiment, the controlled system 104 generates the one or more images responsive to the image generation command and transmits the generated one or more images to the control mechanism 102 for display on the display screen 306. In one embodiment, the controlled system 104 transmits the image generation command to the control mechanism 102 and the control mechanism 102 responsively generates the one or more images for display on the display screen 306. The optical coupling system 308 transmits at least a portion of the one or more images displayed on the display screen 306 for display in the display area of the housing 302. In one embodiment, at least a portion of the one or more images displayed in the display area 106 has generally the same orientation as the one or more images displayed on the display screen 306.
In one embodiment, the housing 302 is moveable from a reference position to one or more different positions relative to the reference position where the relative movement of the housing 302 defines the input data selected by the user. The current position of the housing 302 is defined as the reference position. In one embodiment, the reference position is the initial position that the housing 302 was placed in during or immediately prior to initialization of the controlled system 104. In one embodiment, the reference position changes every time the user selectively moves the relative position of the housing 302 to provide selected input data to the controlled system 104. More specifically, the position of the housing 302 associated with providing selected input data becomes the reference position for the next time the user selectively moves the position of the housing 302 to provided input data to the controlled system 104. When the user wishes to provide desired input data, the user moves the housing from the reference position to a relative position associated with the desired input data. The input sensor 304 senses the relative movement of the housing 302 from the reference position to the selected relative position and the detected relative housing movement data is transmitted from the control mechanism 102 to the controlled system 104 for processing.
Referring to FIG. 4 an illustration of a perspective view of a cross section of one example of one embodiment of a control mechanism 102′ is shown. The control mechanism 102′ includes a knob shaped housing 302′ that surrounds an optical coupling system 308′ in the form of a cylindrical piece of stacked fiber optic material. The fiber optic material consists of a plurality of optical fibers stacked vertically in the direction of a rotation axis 400. The knob shaped housing 302′ is rotatable about the rotation axis 400 with respect to a housing enclosure 402. The upper surface area of the control mechanism 102′ operates as the display area 106′.
The control mechanism 102′ includes a generally rectangular shaped display screen 306′. The optical coupling system 308′ optically couples a portion of the display screen 306′ to the display area 106′. The optical coupling system 308's optically couples a display screen area 404 that is approximately equal to the circular area to the display area 106′. The image displayed in the display area 106′ generally has the same display orientation as that of the image displayed on the display screen 306′.
A user provides desired input data to the controlled system 104 by rotating the knob shaped housing 302′. In one embodiment, the display can show a position marker, along with markings that appear to remain static with respect to the knob's enclosure. The input sensor 304′ is a position encoder that operates to detect the movement of the knob shaped housing 302′. The detected housing movement data is transmitted to the controlled system 104. An image generated by the controlled system 104 is displayed on the display screen 306′. The optical coupling system 308′ pipes the portion of the displayed image within the circular area 404 of the display screen 306′ for display in the display area 106′.
In one embodiment, the relative rotation of the knob shaped housing 302′ with respect to a reference position defines the input data selected by a user. When the user wishes to provide desired input data, the user moves the housing from the reference position to a relative position associated with the desired input data. The input sensor 304 senses the relative movement of the knob shaped housing 302 from the reference position to the relative position and the detected relative housing movement data is transmitted from the control mechanism 102 to the controlled system 104 for processing. In one embodiment, the input sensor 304′ detects a rate of rotational movement of the knob shaped housing 302′ where the rate of rotational movement of the knob shaped housing 302′ defines the input data entered by the user.
Referring to FIG. 5, an illustration of a perspective view of one example of one embodiment of a control mechanism 102′′ with a partially cutaway enclosure 504 is shown. The control mechanism 102′′ includes a display screen 306′′ with a plurality of push buttons 500 disposed on the surface of the display screen 306′′. The push buttons are retained within openings in an enclosure 504 that covers the display screen 306′′. The push buttons 500 are manufactured using a vertically stacked fiber optic material and operates as both a control mechanism housing 302′′ and as an optical coupling system 308′′. The upper surface of each push button 500 operates as the display area 106′′ for that push button 500. Each individual push button 500 operating as the optical coupling system 308′′ for that push button 500 pipes the portion of an image displayed on the display screen 306′′ adjacent to the lower surface of that push button to the display area 106′′ defined by the upper surface of the push button 500. The portion of the image displayed in the display area 106′′ has generally the same orientation as the orientation of the image displayed on the display screen 306′′.
Each push button 500 is associated with specific input data and can be depressed along a vertical axis 502. A user selects desired input data by pushing down the associated push button 500. In one embodiment, each push button is biased towards an initial unpushed position. The control mechanism 102′′ includes four input sensors 304′′ where an input sensor 304′′ is disposed below each corner of the display screen 306′′. The input sensors 304′′ are pressure sensors.
When a user wishes to enter desired input data, the user depresses the push button 500 (operating as the control mechanism housing 302′′) associated with desired input data along the vertical axis 502. The input sensors 304 detect the movement of the display screen 306′′ responsive to the movement of the push button 500 selected by the user. In other words, each of the four pressure sensors senses the movement of the selected push button housing 500 by sensing the pressure on the display screen 306′′ resulting from the pushing down of the selected push button 500. The sensed push button housing related movement data is transmitted from the control mechanism 102′′ to the controlled system 104 for processing. More specifically, the pressure sensed by each of the four input sensors 304′′ is transmitted to the controlled system for processing.
The controlled system 104 analyzes the received sensed pressure data to determine which one of the plurality of push buttons 500 was depressed by the user and generates an image generation command to display one or more images associated with the input data on the display screen 306′′. Each push button housing 500 pipes the portion of the one or more images displayed on the display screen 306′′ adjacent the lower surface of that push button 500 for display in the display area 106′′ defined by the upper surface of that push button 500.
In one embodiment, the control mechanism 102 is moveable on a planar surface. In one embodiment, the relative movement of the control mechanism 102 on the planar surface defines the specific input data. In one embodiment, the position of the control mechanism 102 on the planar surface defines the input data. In one embodiment, the control mechanism 102 includes a housing 302 having an extension coupled to a groove having a length along a sliding axis. The housing 302 is moveable within the groove along the sliding axis. In one embodiment, the position of the housing 302 along the sliding axis within the groove defines the specific input data being supplied by the control mechanism 102. While a number of different control mechanisms have been described, alternative types of control mechanisms may be used.
Referring to FIG. 6 a flowchart representation of one embodiment of a method of generating images for display in the display area of a control mechanism 102 is shown. An initial image(s) is generated by the controlled system 104 for display in the control mechanism 102 responsive to initialization of the controlled system 104 at step 602. In one embodiment, the controlled system 104 is initialized upon power up. The initial image(s) is transmitted from the controlled system 104 to the control mechanism 102 for display in the display area 106 at step 604. In one embodiment, the initial image(s) displayed in the display area 106 reflects the initial status of the controlled system 104. In one embodiment, the initial image(s) displayed in the display area 106 reflects the initial status of the controlled system 104 with respect to a parameter controlled by the control mechanism 102.
When a user wishes to provide input data to the controlled system 104, the user manipulates the position of the housing 302 to provide the desired input data. The input sensor(s) 304 at the control mechanism 102 sense the movement of the housing 302 and transmits the detected sensor data to the controlled system 104. The sensor data generated by the input sensor(s) 304 is received at the controlled system 104 at step 606.
In one embodiment, different pre-defined sensor data thresholds correlate to different input data. A determination is made regarding whether the received sensor data exceeds any of the pre-defined sensor thresholds at step 608. If the controlled system 104 determines that the sensor data does not exceed any pre-defined sensor thresholds, no further action is taken by the controlled system 104 with respect to the control mechanism 102 at step 610. If the controlled system 104 determines that the sensor data does exceed a pre-defined threshold, the controlled system 104 identifies the input data associated with that pre-defined threshold. The controlled system 104 issues an image generation command to generate image(s) responsive to the received input data for display at the control mechanism 102 at step 612. The controlled system 104 generates the image(s) in accordance with the image generation command at step 614 and transmits the generated image(s) to the control mechanism 102 for display in the display area 106 at step 616. In one embodiment, the image(s) displayed in the display area 106 reflects the status of the controlled system 104 responsive to the received input data. In one embodiment, the image(s) displayed in the display area 106 reflects the status of the controlled system 104 with respect to a parameter controlled by the control mechanism 102.
While the steps in the method 600 have been described in a particular order, the steps may be performed in a different order. A subset of the described steps or additional steps may be performed in addition to the described steps.
Referring to FIG. 7 a flowchart representation of one embodiment of a method 700 of displaying images in the display area 106 of a control mechanism 102 is shown. The control mechanism 102 receives the initial image(s) for display at the control mechanism 102 upon initialization of the controlled system 104 at step 702. The received initial image(s) is displayed on the display screen 306 at step 704. The optical coupling system 308 optically transmits at least a portion of the initial image(s) displayed on the display screen 306 to the display area 106 at step 706. In one embodiment, the display orientation of the initial image(s) on the display screen 306 is generally the same as the display orientation of the initial image(s) in the display area 106. In one embodiment, the initial image(s) displayed in the display area 106 reflects the initial status of the controlled system 104. In one embodiment, the initial image(s) displayed in the display area 106 reflects the initial status of the controlled system 104 with respect to a parameter controlled by the control mechanism 102.
When a user wishes to provide input data to the controlled system 104 via the control mechanism 102, the user manipulates the position of the housing 302 to provide the desired input data. The input sensor(s) 304 at the control mechanism 102 sense the movement of the housing 302. The input sensor(s) generate sensor data responsive to detection of housing movement at step 708 and transmits the sensor data to the controlled system 104 at step 710.
The controlled system 104 analyzes the received sensor data to determine whether a user provided input data to the controlled system 104. If the controlled system 104 determines that input data was provided to the controlled system 104 via the control mechanism 102, the controlled system 104 generates image(s) responsive to the received input data and transmits the generated image(s) to the control mechanism 102. The control mechanism 102 receives the image(s) generated by the controlled system 104 responsive to the input data provided via the control mechanism 102 at step 712. The received image(s) are displayed on the display screen 306 at step 714. The optical coupling system 308 optically transmits at least a portion of the image(s) displayed on the display screen 306 to the display area 106 at step 716. In one embodiment, the orientation of the image(s) on the display screen 306 is generally the same as the orientation of the image(s) in the display area 106. In one embodiment, the image(s) displayed in the display area 106 reflects the status of the controlled system 104. In one embodiment, the image(s) displayed in the display area 106 reflects the status of the controlled system 104 with respect to a parameter controlled by the control mechanism 102.
