1. Field of the Invention
The present invention relates to flexible displays and more particularly to wearable articles utilizing a flexible display.
2. Description of the Related Art
A flexible display is a display that is flexible in nature unlike a more traditional rigid display. A flexible display is a visual display for a computer formed upon a flexible substrate and often relies upon organic light emitting diode (OLED) technology. OLED technology is a flat light emitting technology, constructed through the placement of a series of organic thin films between conductors. Upon applying an electrical current, a bright light is emitted. Thus, OLED can be an effective technology for computer displays. More importantly, because OLED technology does not require a backlight, displays built upon OLED technology are thinner and more efficient than LCD display and can support a flexible substrate.
Curved (concave) display screens are one such display disposed upon a flexible substrate and represent an important new display technology innovation because curved display screens substantially improve display performance by significantly reducing and sometimes eliminating reflections from ambient light sources that washout the on-screen images. By eliminating reflections from ambient light sources, screen readability improves as does image quality. Also, the elimination of washout allows concave displays to run at lower brightness, which increases the power efficiency and battery running time for mobile devices. Of note, the notion of a wearable flexible display has been proposed in connection with curved display screens so that watch type devices may permit viewing of displayed information from different angles.
Embodiments of the present invention address deficiencies of the art in respect to wearable, flexible displays and provide a novel and non-obvious method, system and computer program product for a wearable flexible interface with interlocking modules. In an embodiment of the invention, a wearable flexible interface with interlocking modules includes a substrate integrated into a wristband, and also each of a processor, memory and power source disposed on the substrate, as well as a data bus. A multiplicity of different modules each are coupled to the data bus, each including firmware and a flexible display. Finally, a display controller is disposed on the substrate and coupled to each of the processor, memory, power source and each of the modules by way of the data bus. The display controller includes program code enabled to selectively direct the displaying of a display characteristic of a particular module either in a corresponding flexible display of the particular one of the modules, or in single composite display formed by aggregating the flexible displays of all of the modules.
In one aspect of the embodiment, the display controller selects a display of the display characteristic in the single composite display in response to determining that the substrate is in a flattened state. In another aspect of the embodiment, a sensor is included in each of the modules, such that the display controller selects a display of the display characteristic in the single composite display responsive to a transduced value by the sensor exceeding a threshold value. In yet another aspect of the embodiment, gaze tracking logic is coupled to the processor and identifies a focal point on the modules of a human gaze, such that the display controller selects a display of the display characteristic in the single composite display responsive to the gaze tracking logic identifying a focal point on the particular one of the modules. Finally, in even yet another aspect of the embodiment, an accelerometer is coupled to the processor so as to detect a particular movement of the interface, such that the display controller selects a display of the display characteristic in the single composite display responsive to the accelerometer detecting the particular movement of the interface.
Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.
The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein:
Embodiments of the invention provide for a wearable flexible interface with interlocking modules. In accordance with an embodiment of the invention, different separable segments of a flexible display can be coupled to a data bus disposed on a wristband containing an underlying data processing system. Selected ones of the segments can include different biometric sensors including temperature, pulse and pH sensors. Each display portion of each segment once positioned on the wristband can be combined into a composite display controlled by the underlying data processing system of the wristband. In this way, in response to a sensed data value by one of the sensors of a corresponding one of the segments having exceeded a threshold value, the entirety of the composite display can be controlled to provide an associated display characteristic. Further, responsive to a physical orientation of the wristband, the entirety of the composite display can be controlled to provide an associated display characteristic.
In further illustration,
Each of the modules 120 also can include a corresponding sensor 150 embedded therein. Each sensor 150 in turn can be enabled to transduce a real world physical signal such as temperature, pH or pulse rate. In response to the transduction of a real world physical signal by one of the sensors 150 of a corresponding one of the modules 120, a display characteristic 130 of the corresponding one of the modules 120 can be displayed in a flexible display of the corresponding one of the modules 120 in association with the signal transduced by the one of the sensors 150. Notably, the display characteristics 130 in each flexible display of the corresponding modules 120 can be cooperatively controlled by the substrate 110 to provide for an aggregate display 160. In particular, when a value of a signal transduced by one of the sensors 150 exceeds a threshold value, a display characteristic 130 for the transduced signal can be displayed in the aggregate display 160 rather than in only a single flexible display of a corresponding one of the modules 120. As an alternative, when the flexible interface 100 takes on a particular orientation such as being laid out flat, the aggregate display 160 can be provided in lieu of providing an individual display for each corresponding one of the modules 120.
The process described in connection with
A data bus 260 can be disposed upon the substrate 200 and communicatively linked to the processor 220 and memory 230. The data bus 260 can receive multiple different modules, each including module firmware 270A . . . 270N and a flexible display 290A . . . 290N. The flexible display 290A . . . 290N can be enabled for control by the display controller 250 to display different display characteristics such as text or imagery or both. The module firmware 270A . . . 270N can include program code consisting of different program instructions able to be loaded into the memory 230 and executed by the processor 220 so as to control a selection of display characteristics to be displayed in the flexible display 290A . . . 290N.
Of note, a sensor 290A . . . 290N can be included as part of a module. The sensor 290A . . . 290N can be configured to transduce one or more natural phenomena such as the pulse of a human being, the temperature or acidity of the human body or outside air, or other such natural conditions. The sensor 290A . . . 290N can be coupled to the processor 220 by way of the data bus 260 and processed according to instructions of the firmware 270A . . . 270N so as to trigger a display of different display characteristics in the flexible display 290A . . . 290N. In this regard, the instructions of the firmware 270A . . . 270N can be enabled to display a particular display characteristic responsive to a transduced value from the sensor 280A . . . 280N exceeding a threshold value.
Optionally, the processor 220 can determine whether or not the substrate 200 is configured in an elliptical state or in a flattened state. In response to a determination that the substrate 200 is configured in an elliptical state, display characteristics for each individual module can be determined based upon the firmware of each respective module and separately displayed in a corresponding one of the flexible displays 290A . . . 290N. In contrast, in response to a determination that the substrate 200 is configured in a flattened state, the display controller 250 can aggregate the flexible displays 290A . . . 290N into a single composite display and only the display characteristics for single one of the modules can be displayed in the single composite display.
Gaze tracking logic 210A also can be coupled to the data bus 260 and incorporated into the substrate 200. The gaze tracking logic 210A can be configured to identify a focal point of a human gaze upon one of the modules. As such, responsive to determining a particular module associated with a focal point of a gaze of the wearer of the wristband, the gaze tracking logic 210A can indicate to the display controller 250 to aggregate the flexible displays 290A . . . 290N into a single composite display and to display a display characteristic of the module corresponding to the focal point of the gaze upon the single composite display.
Yet further, an accelerometer 210B can be coupled to the data bus 260 and incorporated into the substrate 200. The accelerometer 210B can be configured to detect different movements of the wristband. In response to a specific movement of the wristband, a particular one of the modules can be selected and the accelerometer 210B can indicate to the display controller 250 to aggregate the flexible displays 290A . . . 290N into a single composite display and to display a display characteristic of the particular one of the modules upon the single composite display.
