DESCRIPTION
The present system and approach may incorporate one or more processors, computers, controllers, user interfaces, wireless and/or wire connections, and/or the like, in an implementation described and/or shown herein.
This description may provide one or more illustrative and specific examples or ways of implementing the present system and approach. There may be numerous other examples or ways of implementing the system and approach.
Heating, ventilation and air conditioning (HVAC) wall modules, thermostats and other devices may be typically implemented with buttons with fixed functionality, position and response. These buttons may be mechanical with a preset actuation and functionality. This might not necessarily allow for flexibility and expansion in, for example, HVAC systems.
A sensing area (capacitive in the present example) on a wall module (touchpad like) may result in a possibility of new levels of flexibility. The area may provide a possibility to control wall modules through icons on the display, sensing of discrete finger positions, support gestures, and the like. This system may also be flexible because it can allow programmable functionality from the sensing area. Complete sensing area may reacts accordingly to the application, situation, implementation, and so forth.
Technologies such as resistive touch layer over a display, a capacitive sensing layer over the display or touchpad solutions in general may be used on the devices. The sensing layer may be used and implemented on the surface layer of, for example, a wall module. The sensing area may then be harnessed in a freely programmable way with only changes in application programming.
Creating custom user interfaces (wall modules as examples in this case) for each application (lighting, HVAC, security, and so forth) and each brand using different design languages may be slow and costly. There appears to be a need to create separate button configurations, hardware implementations and firmware to accommodate different arrangements. The terms “button”, “key”, “touch point”, “sub-area”, “switch”, “sub-circuit”, “label” and like words, may be used interchangeably in the present description.
The present disclosure may solve the issue by allowing the wall module or other device with a display and buttons to essentially learn where the buttons are by touching them. So rather than designing dedicated non-flexible user interface solutions, one may start with a generic solution that is quickly tailored to individual needs. The solution could be implemented at design time, at production time, or by end customers depending on a system level implementation.
The present device may be implanted with a capacitive sensing grid area over the user interface surface. The grid overlay may be coupled with a capacitive sense sub-circuit and firmware framework to allow one to quickly move button locations and functions around on the interface surface.
FIG. 1 is a diagram of an example device such as a wall module, thermostat or device 11 often associated with a heating, ventilation and air conditioning system (HVAC). Device 11 may be also associated with security, fire, lighting and other systems. Device 11 may have a display 12, and function select buttons 13 and 14. Where appropriate or needed, device 11 may have magnitude or quantity adjustment buttons 15 and 16.
FIG. 2 is a diagram of a device 21 having a display 22, and a touch sensitive area 23. Sensitive area 23 may have a capacitive touch layer, a resistive touch layer, or other technology type touch layer. The touch sensing area may be harnessed in a freely programmable way with changes in application programming.
Area 23 may be, for example, be implanted with a capacitive sensing grid. Area 23 may have a thin layer with labels, such as numbers and/or letters designating various touch regions. The thin layer may be replaceable with another thin layer or layers having different labels as desired.
FIG. 3 is a diagram of an example device 31 incorporating a user touch interface area 33 having a label layer 34 situated on or adhered to an area 33. Label layer 34 may have fifteen distinct sub-areas 35 of sensitivity. However, there may be more or fewer sub-areas than fifteen for distinct tactile sensitivity of a certain area having respective labels. A signal initiated by the certain sub-area being touched may be assigned a function shown on a display 32. The function may be assigned to a selected sub-area 35, by touching a name on display 32 representing the function shown on the display.
A touch type display 32 may contain virtually all of the buttons and areas desired for scrolling and assigning functions, for selecting temporary buttons and their labels which may be changed on the display, for permanent buttons, and for other components and actions. These items may be effected electronically and by programming.
An example of operation may be noted; however, there can be variants of procedures for operation of device 31. For an illustrative example, a “P” (program) button 36 may be pressed to bring functions up on display 32. The functions may be scrolled up or down on display 32 with buttons or keys 37 and 38, respectively. One of the keys or buttons 41-50, having labels from “1” to “0”, respectively, may be pressed to select the key or button to be assigned the function shown at a center of display 32, as noted by an arrow or other indicator. For instance, button 45 with a label indicating “5” may be pressed for assigning “Function T” to button 45. Button 51 with a label indicating “A” may be pressed to accept Function T as being assigned to button 45 with label “5”. Display 32 may return to a normal operating state for the thermostat, wall module or the like of device 31, after a brief period of time which may be adjusted with an assignment of a function to a key having a particular label. When device 31 is in a normal operating state (i.e., a non-programming state), button 45 with label “5” may be pressed to go to Function T. Function T may be a temperature setpoint for a space. The setpoint may be changed or adjusted by pressing up button 37 to increase the setpoint or down button 38 to decrease the setpoint. The temperature setpoint may be displayed as a separate item by itself, or as a highlighted item on a display 32 showing a number of various items at once. Button 52 may have a label “C” which may be used for closing an assignment of a function to a button or closing a specific function brought to display 32 after pressing the pertinent button being assigned the specific button, for instance, in a case of an adjustment of setpoint or selection.
A combination of buttons in a program mode after pressing button 36 with the label “P” may be pressed for a particular function assignment. For example, buttons 42, 47 and 49 may be pressed for number 279, according to the respective labels “2”, “7” and “9”, for assignment of a function selected on the display which may be accepted by pressing button 51 with the label A. To obtain a function assigned to number 279, the buttons for labels “2”, “7” and “9” may be sequentially pressed during the normal operating state to get the function assigned to number 279.
The buttons may be reassigned functions different from the functions previously assigned to the buttons. For example, button 45 with label “5” having been assigned “Function T” may be pressed after button 36 with label “P” has been pressed, and reassigned another function selected on display 32, such as “Function H”. Button 51 with label “A” may be pressed to accept the assignment, or after a period of time the assignment, without pressing button 51, may be accepted and display 32 can return to a state for normal operation of device 31. Alternatively, if button 51 is not pressed to accept the assignment, display 32 may after a period of time return to the state for normal operation without effecting the assignment of the selected function to the button 51 pressed for assignment of the selected function. The period of time may be adjusted through selection and assignment of another function to a designated button. Functions to be assigned to designated buttons may be represented by, for example, names, labels, symbols, icons or codes on the display, which may be selected and assigned to the respective keys. A code may be entered to lock the buttons to their assigned functions so that changes made intentionally or unintentionally are ineffective.
FIG. 4 is a diagram of a thermostat, wall module or device 54 having a touch display 55 with buttons 36-38 and 41-52 on touch sensitive surface 33 of device 31 being substituted with touch sensitive buttons 56-58 and 61-72, respectively, on touch display 55. Device 54 may be operated in a same manner as device 31.
Alternatively, the functions on display 55 may be scrolled with a finger on the display in lieu of buttons 57 and 58. A function on display 55 may be accepted or assigned to a selected button with a tap or double tap on the function label, name, symbol, icon, code, or the like, on display 55 in lieu of touching button 71 with label “A”. The labels for buttons 56-58 and 61-72 may be changed electronically via programming that may be part of the functionally of device 54. An arrangement, configuration and number of sensitive areas on display 55 may also be changed. An amount of flexibility available or desired may be designed into device 54, according to choices and needs of a user or customer.
FIG. 5a is a diagram of columns of electrodes 81 for a capacitive touch area. FIG. 5b is a diagram of rows of electrodes 82. The columns of electrodes and the rows of electrodes may be overlapped proximate to each other, as shown in a resulting layout 85 of a diagram of FIG. 6, and have a thin dielectric film situated between them to avoid electrical shorts. A touch on a capacitive area may change the capacitance between an electrode of a specific row and an electrode of a specific column. The change of capacitance may be electronically detected and a location of the changed capacitance can be determined in a grid fashion by a row number and column number of the electrodes. For example, a touch at location 84 may be result in a change of capacitance between an electrode 83 at row 3 and an electrode 84 at column 4. The subject electrode elements 84 and 83 may be as shown in the electrode layouts 81 and 82, and resulting layout 85 in the diagrams of FIGS. 5a, 5b and 6, respectively. There may be virtually any number of rows and columns of electrodes in a touch sensitive area.
FIG. 7 is a diagram showing a perspective view of a fabricated touch sensitive area 85.
FIGS. 8a, 8b and 8c are diagrams of various examples of configurations of layouts 91, 92 and 93, respectively, that may be overlaid on a touch sensitive area or display as discussed herein.
FIGS. 9a, 9b and 9c are diagrams of additional configurations of layouts 94, 95 and 96 of buttons or keys that may be overlaid on a touch sensitive area or display as discussed herein. Other layouts may have some of the buttons, keys or the like, on the touch sensitive keyboard and, some on the touch sensitive display. Also, there may be buttons that are not touch sensitive situated on the module, thermostat or device.
FIG. 10 is a diagram of a schematic of example circuitry 98 that may be utilized at least in part for the present customizable user interface disclosed herein.
