Exemplary embodiments relate generally to systems and methods for monitoring the status of a touchscreen.
Increasing supply and decreasing costs have resulted in a greater utilization of touchscreen technology. Such touchscreens are increasingly being used in a number of applications. One such exemplary application is the digital out of home (“DOOH”) advertising industry. DOOH applications include indoor, semi-outdoor, and outdoor digital signage.
Some touchscreens require physical depression (e.g., resistive type), while others require contact with a conductive item (e.g., capacitive type). Some touchscreens suffer from inaccurate touch capture, some have slow response speeds, and many touchscreens are only capable of receiving a limited number of touch inputs at a given time. The use of sigma-delta modulation technology and/or in-cell concurrent capacitive imaging (herein interchangeably referred to as “ICCI”) may overcome some or all of these, and other, deficiencies. Such ICCI technology is available from, for example without limitation, SigmaSense, LLC of Austin Texas (see sigmasense.com). Such ICCI technology may comprise, for example without limitation, systems and method which energize an entire touchscreen array while the touchscreen is operated and monitor for signal reflections. The touchscreen's steady-state behavior may be monitored and used as a baseline to determine anomalous behavior, such as user input.
Touchscreens, particularly those in DOOH applications, may be exposed to harsh conditions. Such harsh conditions may include, for example without limitation, vandalism, smudging, wildlife, other environmental hazards, rain, sun, sleet, snow, high winds, other weather conditions, accidents, some combination thereof, or the like. Such harsh conditions may cause damage affecting the touchscreen's functionality and may result in operational downtime. Even if such damage does not affect functionality of the touchscreen, it may affect visibility-which can impact revenue, especially in the DOOH market.
Even if a touchscreen is remotely monitored, not all damage will be sufficient to trigger an alert. For example, such alerts may be generated only upon certain failure type events. Systems may not exist to monitor for other levels of damage such as, but not limited to, surface scratches, smudges, obstructions, screen cracks, or similar. Furthermore, even if an alert is generated, there is insufficient information provided to determine the type of damage to the touchscreen. For example, a remote user may be unable to determine if the whole unit needs replaced, and therefore a skilled team with replacement parts needs to be dispatched to make the repair, or if the unit is only lightly damaged in an easily repaired fashion (e.g., excess smudging or bird excrement) which might require only an unskilled technician to wipe down the screen.
What is needed is a system and method for monitoring the status of a touchscreen. Systems and methods for monitoring the status of a touchscreen are provided. One or more display assemblies may be in communication with a network operations center. Each display assembly may comprise one or more touchscreens, one or more touchscreen controllers, and a network communications device. The touchscreens may utilize ICCI technology. The touchscreens may be monitored periodically, or continuously, for damage. Such monitoring may be reported in substantially real time. The presence of damage may be determined by detecting interruptions in the touchscreen signals distributed across the touchscreen by the touchscreen controller. For example, without limitation, persisting touch input at a given area may indicate a first type of damage, persistent signal interruption across a portion of the touchscreen may indicate a second type of damage, and persistent signal interruption to the entire touchscreen may indicate a third type of damage. The location of damage may be determined based on the area where the signal is interrupted. A visual representation of the touchscreen, along with a visual representation of damage thereto, may be generated. The visual representation may indicate the type and/or location of the damage.
It may be desirable to incorporate the touchscreen into a ruggedized subassembly. The touchscreen may comprise multiple components and/or layers which provide protection, improve optical quality, facilitate thermal management, combinations thereof, or the like.

Electronic communication with the display assemblies 100a-100n may be accomplished by way of network communication devices 106 located at each respective display assembly 100a-100n. Such electronic communication may be realized through wired connections, wireless connections, some combination thereof, or the like. Such networks may comprise internets, intranets, the world wide web, cellular networks, some combination thereof, or the like. Each display assembly 100a-100n may comprise one or more touchscreen electronic displays 102 (hereinafter also, touchscreens 102). The touchscreens 102 may comprise liquid crystal displays, organic light emitting diode displays, plasma displays, or the like. Furthermore, the touchscreens 102 may be directly backlit or edge lit. The touchscreens 102 may further comprise various anti-glare layers, anti-smudge layers, protective layers, and the like. In exemplary embodiments, the touchscreens 102 utilize ICCI technology, though any type of touchscreen technology may be utilized.
If a respective display assembly 100a-100n comprises more than one touchscreen 102. Such touchscreens 102 may be arranged back to back, side by side, above and below one another, some combination thereof, or the like. Each of the touchscreens 102 may be operable by way of touch input. A touchscreen controller 104 may be placed in electronic communication with one or more of the touchscreens 102 in a respective display assembly 100a-100n. Upon receipt of touch input at the touchscreen 102, the touchscreen controller 104 may command the touchscreen 102 to alter the image displayed thereon based upon the touch input as received and processed at the touchscreen controller 104. The touchscreen controller 104 may, alternatively or additionally, monitor for touch input at the one or more of the touchscreens 102.
Where a given display assembly 100a-100n comprises more than one touchscreen 102, more than one touchscreen controller 104 may be utilized, though such is not required. Each of the touchscreen controllers 104 may comprise software utilizing ICCI technology. Such ICCI technology and software may be available from, for example without limitation, SigmaSense, LLC of Austin Texas (see sigmasense.com/). The touchscreen controllers 104 may be configured to monitor the touchscreens 102 for touch input and may change the image displayed on the respective touchscreen 102 in response to the received touch input. Activity recorded by the touchscreen controllers 104, and/or images displayed on the touchscreen 102, may be remotely monitored at the network operations center 120 and/or at other remotely located electronic devices 121 by way of the network communications device 106.
Each display assembly 100a-100n may comprise a housing 108. The housing 108 may partially or wholly enclose the electronic display(s) 102, the touchscreen controller(s) 104, and the network communication device 106 for the respective display assembly 100a-100n. The housing 108 may be ruggedized such that the display assembly 100a-100n may withstand various environmental conditions such as, but not limited to, rain, snow, wind, high temperatures, low temperatures, sunlight, hail, sleet, physical impact, vandalism, and the like.
A closed loop pathway for circulating air 114 may also be provided within the respective display assembly 100a-100n in exemplary embodiments, without limitation. The closed loop pathway may be in thermal communication with some or all of the components of the respective display assembly 100a-100n so as to remove heat generated by such components. The closed loop pathway may be placed in thermal communication with the open loop pathway to transfer heat from the circulating gas 114 to the ambient air 112. The ambient air 112 may also provide cooling for the display assembly 100a and various components thereof. Such thermal communication may be accomplished by way of an air to air heat exchanger. In this way, the circulating gas 114 may remain substantially free from contaminants that may otherwise be present in the ambient air 112. One or more fans may be provided along the closed loop pathway to facilitate the movement of the circulating gas 114. In exemplary embodiments, the closed loop pathway may pass between a transparent cover for, and a display surface of, the touchscreen 102. The various display assemblies 100a-100n may be the same or different from one another.
Referring particularly to
If damage is detected, the type and location of the damage may be identified. Identification of the type of damage may be achieved by determining the level of interference with touchscreen signals being generated and transmitted across the touchscreen 102 by the touchscreen controllers 104. For example, without limitation, if a signal is only partially interrupted or weakened, it may be determined that a first type of damage has occurred. Such first types of damage may include, for example without limitation, surface obstructions. If a signal is completely interrupted, it may be determined that a second type of damage has occurred. Such second types of damage may include, for example without limitation, scratches, cracks, or other physical damage. If no signals are returned whatsoever, it may be determined that a third type of damage has occurred. Such third types of damage may include, for example without limitation, failure or downtime events.
Alternatively, or additionally, and referring particularly to
If such signal interruptions do not represent touch input, the touchscreen controllers 104 may determine if the interruption is over part of all of the touchscreen 102. The touchscreen controllers 104 may, for example without limitation, determined that the interruption does not constitute touch input where the interruption indicates missing signals, scrambled signals, some combination thereof, or the like. If the interruption is over part of the touchscreen 102, the touchscreen controllers 104 may determine that the second type of damage has occurred. If the interruption is over the enrage touchscreen 102, the touchscreen controllers 104 may determine that the third type of damage has occurred.
Identification of the location of the damage may be achieved by determining the locations on the touchscreen 102 where signals from the touchscreen controllers 104 are interrupted. The entire touchscreen 102 may be scanned to outline the area(s) where the signals are interrupted.

The damage 132 illustrated in the visual representation 130 may be color coded or patterned to indicate that the damage 132 is a first, second, or third type of damage. The visual representations 132 may be updated in substantially real time and such updates may be performed continuously or at any interval. The repair requests may request that photographic evidence be provided of completed jobs.
In exemplary embodiments, such as but not limited to, where the touchscreens 102 utilize ICCI technology, signal interruptions may be determined where received signals vary from an established steady-state behavior. Steady-state behavior may be determined by energizing an entire array for the touchscreen and monitoring the touchscreen for an initial period of time to establish steady-state behavior. Exemplary touch input may be provided to determine exemplary touch input. In such embodiments, comparisons may be made against exemplary touch input to determine signal interruptions which do or do not represent touch input. Regardless, where signal behavior varies from the established steady-state behavior, a determination may be made that the signal is interrupted. Alternatively, or additionally, signal interruption may be determined where no signals are received following transmission.
