Companies may designate physical locations (e.g., rooms) within their operating spaces as meeting spaces. These meeting spaces may include various projectors and displays that allow meeting attendees to simultaneously view content controlled by, for example, a presenter. The companies may employ a variety of scheduling techniques and/or solutions to reduce competition over meeting room space.
The present application may be more fully appreciated in connection with the following detailed description taken in conjunction with the accompanying drawings, in which like reference characters refer to like parts throughout, and in which:
Systems, methods, and equivalents associated with projection device access are described. Access to a projection device in a physical space may be provided by generating a secret key when a user successfully reserves the physical space (e.g., for a meeting) in which the projection device is located. The secret key may also be provided, during the time period associated with the reservation, to an access module that controls access to the projection device. This may allow the user to launch a screen sharing module that facilitates showing images using the projection device. The screen sharing module may make the secret key available to the access module controlling the projection device, which may then allow the screen sharing module to control the projector to project, into the physical space, images provided from the device operating the screen sharing module.
However, physical space 160 may be a shared resource that is used, at various times, by many different people from an organization with which the user is associated. This may make physical space 160 a limited resource as multiple people operating within the same space on unrelated tasks may interfere with one another. Consequently, the organization may employ a scheduling module 130 to manage reservations of physical space 160. Scheduling module 130 may manage reservations of physical space 160 by, for example, ensuring persons scheduling reservations have appropriate permissions for reserving physical space 160, ensuring that reservations of physical space 160 do not conflict with each other (e.g., by occurring during overlapping time periods), and so forth.
When the time comes for the user to give their presentation, the user may connect device 110 to projector 180 to cause presentation 120 to be shown on display 185. If the user is physically present with device 110 within physical space 160, device 110 may connect via a cable or local wireless technology (e.g., Bluetooth, a local wireless network) to projector 180. However, when physical cables are used to connect device 110 to projector 180, certain devices 110 may be unable to connect if the proper cable connection does not exist in the device. When wireless networks are used, again assuming the appropriate hardware, applications, and/or operating systems are functioning on device 110, projector 180 and device 110 may need to be on the same network. This may kick device 110 off of another network, potentially preventing device 110 from accessing content intended for display. Further, because these pairings may be remembered by device 110 and projector 180, it may be possible for non-authorized users operating on the network to use projector 180 at the same time as an authorized user user, or for users to inadvertently interfere with one-another's presentations.
Additionally, significant time may be spent setting up projection as the user attempts to figure out the proper cables to connect, settings on device 110 and projector 180, and so forth to cause presentation 120 to be shown on display 185. In other examples, to facilitate the user presenting from a remote location, some organizations setup intermediary computers that are locally connected to projectors. In this scenario, a local user may set up the intermediary computer by, for example, setting up a screen sharing application on the intermediary computer and connecting the intermediary computer to projector 180, thereby effectively connecting device 110 to projector 180.
Instead, systems and methods disclosed herein may leverage infrastructure to automatically facilitate connections between device 110 and projector 180 to enable showing presentations 120 within physical space 160 without a complicated setup process involving a person physically present within physical space 160 to set up device 110 and/or projector 180. After reserving the physical space 160 via scheduling module 130, the user may receive a secret key from the scheduling module 130. The secret key may be received via the same infrastructure used to reserve physical space 160. By way of illustration, scheduling module 130 may be incorporated into an organization's email-based system for managing room reservations. Here, the scheduling module may be a set of scripts operating, for example, in association with an Exchange server. Consequently, when a user sends an email or meeting request to an email address associated with a physical space 160, the scheduling module may determine whether any time conflicts exist and whether the user has appropriate permissions. Subsequently, the email service may block off the time to prevent conflicts from occurring in the future, and send an email back to the user indicating that physical, space 160 has been reserved. This email may include the secret key.
When the user seeks to begin displaying presentation 120 within physical space 160, device 110 may attempt to connect to a control device 170. In this example, control device 170 is illustrated within physical space 160. In other examples, control device 170 may be located remotely. Control device 170 may be, for example, a system-on-a-chip that acts as an intermediary between device 110 and projector 180 to facilitate showing images received from device 110 on display 185.
To connect to control device 170, device 110 may provide the secret key received from scheduling module 130 to control device 170. Consequently, scheduling module 130 may also make the secret key available to control device 170 (e.g., by providing the secret key to the control device). In various examples device 110 may provide the secret key to control device 170 via a screen sharing module. The screen sharing module may be obtained from an external sever (not shown) associated with scheduling module 130 and/or control device 170. In some examples, a hyperlink in an email may cause device 110 to access a website that runs the screen sharing module (e.g., as a web based application). Consequently, the screen sharing module may be a device agnostic module that may operate without prior special configuration of device 110, control device 170, and/or projector 180. The screen sharing module may then use the secret key to connect device 110 with control device 170. In another example, the screen sharing module may operate as an add-on to, or be retrieved by, another application (e.g., web browser, email client) already operating on device 110.
In various examples, the secret key may serve as a security measure that prevents improper access to control device 170 and projector 180. Because scheduling module 130 may ensure that users reserving physical space 160 have corresponding access permissions, secret keys may be sent to persons approved to use physical space 160 and/or projector 180. Additionally, the secret key may be provided to control device 170 for a limited time period associated with the reservations. This may deter, for example, a user who has reserved physical space 170 from extending their meeting past the end of their reservation into a time period associated with another reservation. The limited time period for which the secret key may function may depend on various factors. By way of illustration, scheduling module 130 may provide the secret key to control device 170 for exactly the time period associated with the reservation. In other examples, scheduling module 130 may extend a window during which the secret key functions to accommodate setup time and/or a meeting running beyond a reservation period. Extended windows may be avoided in scenarios where two reservations operate in consecutive time periods.
Once device 110 has connected to control device 170 by providing control device 170 the secret key, control device may configure projector 180 to facilitate displaying images received from device 110. Configuring projector 180 may include, for example, turning on projector 180, changing display settings on projector 180, setting an input mode of projector 180, and so forth. After configuring projector 180, control device 170 may continue serving as an intermediary between device 110 and projector 180 to facilitate showing presentation 120 into physical space 160. When control device 170 is capable of turning on projector 180, control device 170 may also be able to turn off projector 180 once device 110 is no longer seeking to show images into physical space 160 via projector 180.
