In various input areas, interfaces are commonly become touchable. A touchable interface employs a touch surface or touch display (for example, capacitive or resistive touching), and reacts to a touch on a predefined portion of the surface or the display. In response to the touch, an electrical system is configured to perform a command based on the coordinate of the touch.
One such environment in which touch displays are becoming more common is vehicles. Touch screens provide an aesthetically pleasing experience, while being capable of providing a multitude of control options. Thus, a single interface may be employed to control temperature, audio, lighting, and the like. Accordingly, an implementer of a touch display system may conserve valuable real estate in the dashboard or cockpit area.
In situations where a touch display is employed, graphical user interface (GUI) elements provide an indication to an operator on the actions associated with the touch of a specific location. The GUI element may be any sort of digital indication, such as a static icon, a moving icon (i.e. mosaic icon), text, or combinations thereof.
In certain cases, the GUI element may initiate an opening of a secondary screen. The secondary screen may contain action items that are touchable as well. In certain cases, the display size may be limited, and thus, the secondary actions may be hidden until a parent GUI element is activated. The justification for an implementation such as the above is that the screen may not be capable of displaying every secondary action. Accordingly, a secondary action (or menu of action items) may only be displayed when requested.
A system and method for providing a callout based on a detected orientation is illustrated. The system includes a touch detector to detect an input to an interface; a callout detector to detect whether a callout is associated with the input; an orientation detector to determine a direction of the input, and a callout display driver to indicate a position of the callout based on the determined direction.
Other advantages of the present disclosure will be readily appreciated, as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
a) and 5(b) illustrate an example of the system of
Detailed examples of the present disclosure are provided herein; however, it is to be understood that the disclosed examples are merely exemplary and may be embodied in various and alternative forms. It is not intended that these examples illustrate and describe all possible forms of the disclosure. Rather, the words used in the specification are words of description rather than limitation, and it is understood that various changes may be made without departing from the spirit and scope of the disclosure.
An interface may be provided via a touch display. As explained in the background section, the interface serves as conduit between an operator and a system (for example, a vehicular control system). In response to an operator interacting with the interface, an electrical signal is transmitted to the vehicular control system. The vehicular control system may adjust the display of the touch display, accordingly.
A touch display may present information in a hierarchical manner. For example, a primary level of GUI elements may be presented, and when each of the primary level of GUI elements is interacted with, a secondary level of GUI elements may be presented. In this way, a singular touch display may be employed to present multiple menu items and system controls to an operator.
When one of the GUI elements is interacted with, a “callout” may be presented accordingly. The callout is essentially a secondary GUI element with additional action items. For example, if an operator initiates a GUI element for one of the items associated with the primary level, a secondary level (i.e. a menu, list, or additional GUI elements) may be presented.
In the field of touch screen displays, a finger or pointing apparatus may be employed to initiate contact with the GUI element. In response to the finger touching the display, the callout screen may be presented. Accordingly, the finger may block the callout screen, thus causing the operator to be annoyed and the user-experience to be lessened.
Disclosed herein are systems and methods for providing a callout based on a detected orientation. Accordingly, because the system and methods disclosed herein detect where an operator is relative to a GUI element, the callout screen may be provided in a non-hindered location of the touch screen display. In this way, the user-experience may be optimized and critical information association with the operation of an electronic system is presented in a more efficient manner. In systems where safety is paramount, such a vehicular control system, and an operator may spend less time interacting with the interface, and thus, experience a safer driving experience.

The touch display 250 may interact with a system bus 260. The system 200 may also interact with the system bus 260. The system bus 260 may control various devices and electronic systems. Based on an operator's interaction with the touch display 250, a feedback signal received from the system bus 260 may interact with the touch display 250, thereby modifying the presentation of information on the touch display 250. An operator may dynamically interact with the touch display 250, with various presentation screens being presented responsive to the operator's interaction.
Referring to
The touch detector 210 detects that a touch associated with touch display 250. For example, an operator may touch any of GUI elements 251-253, thereby initiating the system bus associated with the touch display 250 to perform an action. The touch detector 210 may detect which GUI element is touched. Alternatively, the touch detector 210 may be configured to not be cognizant of which element is activated.
The callout detector 220 determines whether a callout is associated with the detected touch, via touch detector 210. The system bus 260 may communicate with a data storage, such as persistent store 265, and record instructions associated with the GUI elements, such as GUI elements 251-253. The persistent store 265 may maintain a lookup table 266, with indications of whether each of the GUI elements is associated with a callout. Additionally, the lookup table 266 may also maintain information associated with the callouts size, and the menu items or additional GUI elements associated with the callout.
The orientation detector 230 detects the direction of approach associated with the touch. The orientation detector 230 may accomplish the determination through various techniques, which will be described further in regards to
The orientation detector 230 may employ eye tracking or head tracking to further control the GUI elements or to determine orientation. Alternatively, capacitive sensing technology may be implemented to further determine the orientation.
The callout display driver 240 transmits to the system bus 260 location information associated with the display of the callout 255. The location of the callout 255 may be determined in a location opposite the operator the touch display 250. For example, if the operator of the touch device is seated to the left of the touch display 250, the callout display driver 240 may transmit an indication to display the callout 255 to a portion of the screen to the right of the GUI element. In this way, a finger, hand or pointing apparatus may not effectively block a presentation of information associated with the callout 255. The system bus 260 may transmit the indication to the touch display 250.
The callout may be provided with an incremental GUI element. The incremental GUI element allows for step based settings of various control items. For example, the callout may have various icons indicating various settings. Every time one of the icons is either asserted or de-asserted, the setting of the associated control may be adjusted accordingly.
In one example, the orientation detector 230 may be implemented with a camera 231. The camera 231 captures an image or video of the operator approaching the touch display 250. Based on the captured image, the orientation detector 230 may ascertain where the operator is relative to the touch display 250. The camera 231 may be installed in a system for another purpose, such as aiding a vehicle or an electronic system perform gaze tracking.
In another example, the orientation detector 230 may be equipped and configured with an angle/pressure detector 232. By employing the angle/pressure detector 232, the touch display 250 is capable of detecting the angle and approach of a touch to the touch display 250. Accordingly, by detecting the angle/pressure associated with a touch, the orientation detector 230 may determine the direction of the touch.
In operation 410, a touch to a touch display is detected. As explained above, the touch display may be implemented along with various electronic systems, such as a touch display in a vehicle.
In operation 420, a determination is made as to which GUI element the touch is associated with. Once the GUI element is ascertained, the method 400 may cross-reference a database to determine whether the GUI element is associated with a callout (operation 430).
In operation 440, if the GUI element is associated with a callout, an orientation of the operator associated with the touch is determined. As explained above in regards to
In operation 450, based on the determined orientation, a placement of the callout is determined. The placement of the callout may be in a portion of the display not blocked by an object, such as the operator's hand. Accordingly, the callout may be visible and easy to access.
In operation 460, the callout location is transmitted to the touch display or a system or processor associated with driving the control of the touch display.
