The following embodiments of the present invention are described in sufficient detail to enable those skilled in the art to make and use the invention. It is to be understood that other embodiments would be evident based on the present disclosure, and that process or mechanical changes may be made without departing from the scope of the present invention.
In the following description, numerous specific details are given to provide a thorough understanding of the invention. However, it will be apparent that the invention may be practiced without these specific details. In order to avoid obscuring the present invention, some well-known circuits, system configurations, and process steps are not disclosed in detail. Likewise, the drawings showing embodiments of the apparatus/device are semi-diagrammatic and not to scale and, particularly, some of the dimensions are for the clarity of presentation and are shown greatly exaggerated in the drawing FIGS.
The term “horizontal” as used herein is defined as a plane parallel to the conventional plane or surface of the Earth, regardless of its orientation. The term “vertical” refers to a direction perpendicular to the horizontal as just defined. Terms, such as “above”, “below”, “bottom”, “top”, “side” (as in “sidewall”), “higher”, “lower”, “upper”, “over”, and “under”, are defined with respect to the horizontal plane. The term “on” means there is direct contact among elements. The term “system” as used herein means and refers to the method and to the apparatus of the present invention in accordance with the context in which the term is used. The term “processing” as used herein includes stamping, forging, patterning, exposure, development, etching, cleaning, and/or removal of the material or laser trimming as required in forming a described structure.
The terms keys and buttons are used interchangeably and should be construed broadly. The term physical buttons and hard keys may be used interchangeably. The term soft key may be thought of as a key on a touch screen that is activated by contacting the touch screen in the designated area of the soft key. The term soft key is to be in contrast with the term hard key. Hard keys may be thought of as physical three dimensional keys as opposed to virtual keys on the touch screen. Soft keys, i.e., a corresponding icon, for example, can be located at different positions on a display screen depending on the mode of operation or the actual operation being performed. Hard keys, by contrast, are generally fixed in a specific location, although the function associated with the hard key may be reassigned via various methods. Thus, the terms soft keys and hard keys have relative meaning and soft keys are generally associated with a display and hard keys are generally not.

While test equipment is discussed for this application, other uses will be apparent from the teachings disclosed herein. The layout arrangement and the number of the hard keys 102 may vary depending on the function of the equipment. The touch screen 104 is a tactile display screen and it may be divided into sections. Inside the data display window 106, one or more of the marker icon 112 can be displayed when the marker function tab 116 is selected on the function soft keys 108. The marker icon 112 may use different symbols, color, display intensity, or a combination thereof to indicate marker state of either ACTIVE or ON. In this embodiment example, the ACTIVE marker icon is presented by a box symbol with a higher intensity than the surrounding marker icon. The ON but not ACTIVE marker is presented by a triangle symbol with a normal intensity. This is by way of an example and any combination of color, shape, and intensity that may differentiate the marker icon 112.
The number of the marker soft keys 114 indicates how many of the marker icon 112 can be on the data display window 106 at any time. In this embodiment example, there are six of the marker soft keys 114. Each of the marker soft keys 114 is numbered and associated with the marker icon 112 having the same number either next to or inside the marker symbol of either a box or a triangle. The color, shape, and intensity association helps a user to quickly identify the marker icon 112 active location and the marker soft keys 114 active which shows measured parameters on the marker location.
The function soft keys 108 comprise function tabs and each tab comprises several soft keys for that particular function. In this embodiment example, one of the tab functions is the marker function tab 116 that includes the marker lock soft key 110 and the marker control function keys 118. The marker control function keys 118 may be used to manipulate the position of the marker icon 112 relative to the user data 120. In this embodiment example, the touch screen 104 is locked and unlocked using the marker lock soft key 110. When the touch screen 104 is locked, the screen is not sensitive to a contact or touch, therefore the tactile display is in an inactive mode causing the touch screen to be disabled. A user is able to unlock the touch screen 104 with a soft key within the touch screen 104, instead of using any one of the hard keys 102 which is away from the user's field of view. If the user desires, various measurement settings may be altered for further data analysis without unlocking the markers. The marker lock soft key 110 is located inside the touch screen 104. In one embodiment example as shown in
Referring now to
While the marker function mode is selected, as a default operation, the marker lock feature is in an OFF state 202, which means the touch screen 104 in
In order to reactivate the touch screen 104 to be tactilely sensitive again, the marker lock soft key 110 is monitored in a decision block 208. By touching the marker lock soft key 110 on the touch screen 104. The flow returns to the OFF state 202. The touch screen 104 is then unlocked and can accept input through contact with the touch screen 104. The user can continue with other activities such as, select different markers, turn on or off markers, or even start another measurement.
This may be achieved by creating software code that deactivates the display upon touch when the marker lock is in the locked state 206. The deactivation does not apply to the marker lock soft key 110 at any time. The software example is for demonstration purposes and it is clear that the functions discussed above may be implemented in hardware, software, or a combination thereof.
Referring now to
A third decision block 314 checks for the data display window 106 having been touched. If the data display window 106 has not been touched, the flow proceeds to a fourth decision block 318. If the data display window has been touched the flow proceeds to an active marker moves block 316, then progresses to the fourth decision block 318. The fourth decision block 318 monitors for the marker soft keys 114 to be touched. If the marker soft keys 114 have not been touched the flow returns to the first decision block 306. If the marker soft keys 114 have been touched the flow proceeds to a fifth decision block 320 to check for the selected marker in the off state. If the selected marker is found to be off, the flow enters a marker on and active block 322.
If the selected marker is not off, the flow progresses to a sixth decision block 324 to check for the selected marker in an on state. If the selected marker is on, the flow progresses to a marker active block 326. If the selected marker is not on, the flow progresses to a seventh decision block 328 to check for the marker being active. If the selected marker is active the flow progresses to a marker off block 330 where the selected marker is turned off. If the selected marker is found not to be active, the flow returns to the first decision block 306.
At this time, all of the marker soft keys 114 are shown but only an initial marker becomes active. In this embodiment example, there may be six markers and six delta markers available for most measurement modes. The “active” marker will appear on the touch screen 104 as the marker icon 112 at the “touched” location, exhibiting a square box, colored and highlighted with the corresponding identifier character, such as a number, an identifying symbol, or a letter. The user data values will appear on the active, highlighted on the marker soft keys 114 on the touch screen 104. If necessary, the position of the marker can be changed by pressing the left/right arrow keys of the hard keys 102. In order to activate a marker other than the marker currently being displayed as “active”, simply touch one of the marker soft keys 114 to the right of the touch screen 104, this will be detected by the marker activation system 300. The new marker changes from its former “ON/OFF” status, to its new status as the “active marker”. This means that it can now be moved while the other markers remain in-place. The former “active” marker reverts to an “ON” status, but is no longer the “active” marker.
With “one touch” on the data display window 106, at a desired location in which measurement or parameter extraction is to be done, several events happen at the same time including opening the marker control tab, placing the marker icon 112 at the desired location, activating the marker soft keys 114, making the marker icon 112 the currently active, colored, and highlighted, and recording the user data 120 parameter at that location to be placed on the corresponding marker number of the marker soft keys 114.
Referring to
In this embodiment example, six markers are available though any number of markers may be supported, only the marker soft keys 114 set to ACTIVE state will be highlighted in color; the markers soft keys 114 either in ON or OFF state will exhibit a different distinct color or white background with their respective marker number. To activate a marker other than the marker currently being displayed as “active”, simply touch one of the marker soft keys 114 to the right of the touch screen 104 as indicated in a touch marker soft key block 408. This will result in the new marker changing from its former ON or OFF state, to its new state as the “active marker”, in a activate selected marker block 412, meaning that it can now be moved while the other markers remain in-place. The former “active” marker reverts to an ON state, but is no longer the ACTIVE marker. For example to make marker number 4 active, simply touch the marker soft key 114; the button will be highlighted with a prescribed color, and the marker icon 112 symbol will appear on the screen highlighted with the prescribed color, and the pertinent data for that marker will appear on the now active, highlighted marker 4 button. To change the position of the marker for minor positioning adjustment, you can press the arrow keys on the hard keys 102.
In general, to position markers, touch the screen to make a rough placement, and then use the left/right arrow keys in the hard keys 102 to fine-tune the location, or open the marker function control tab 116, by touching marker soft keys 114 or the data display window 106, to conduct other marker functions such as Marker-to-Peak or Marker Delta.
To remove the marker icon 112 from the data display window 106, touch the marker icon 112 that corresponds to the marker to be removed in a touch marker icon block 410. The marker icon 112 will disappear and the marker soft key 114, of the corresponding marker icon, turns to a marker icon OFF block 414. The next time that the marker is activated it will appear at its previous location on the screen. To remove all markers at once, open the marker function tab 116 and touch All-Markers-Off function in the marker control function keys 118.

An important aspect of the present invention is that it employs a direct touch of the marker icon to reduce the number of key strokes and steps for transitioning between markers to be activated, and provide a well-organized control with visual enhancement for the complex transition of three state marker modes.
These and other valuable aspects of the present invention consequently further the state of the usability, efficiency and responsiveness to at least the next level of enhancing user interface experience in tactile display equipment.
Thus, it has been discovered that the tactile display locking and marker system of the present invention furnish important and heretofore unavailable method and functional aspects for enhancing user interface of tactile display equipped electronics equipment. The resulting processes and configurations are straightforward, cost-effective, uncomplicated, highly versatile, accurate, sensitive, and effective, and can be implemented by adapting known components for ready, efficient, and economical manufacturing, application, and utilization.
While the invention has been described in conjunction with specific best mode using test equipment as embodiment example, it is to be understood that many alternatives, modifications, and variations will be apparent to those skilled in the art in light of the aforegoing description. Accordingly, it is intended to embrace all such alternatives, modifications, and variations which fall within the scope of the included claims. All matters heretofore set forth herein or shown in the accompanying drawings are to be interpreted in an illustrative and non-limiting sense.
