## Title
Notification system for providing awareness of an interactive surface

## Abstract

A system for providing awareness of an interactive surface is disclosed. The system may include a processor that is communicatively linked to an interactive surface. The processor may determine a position and a velocity of an object that is within range of the interactive surface based on one or more of media content, vibrations, air movement, sounds and, global positioning data associated with the object. Additionally, the processor may determine if the object has a trajectory that would cause the object to collide with the interactive surface based on the information associated with the object. If the processor determines that the object has a trajectory that would cause the object to collide with the interactive surface, the processor can generate a notification.

## Background
FIELD OF THE INVENTION
The present application relates to collision warning systems, and more particularly to a system and method for preventing a collision with an interactive surface.
BACKGROUND
In today's technologically-driven society, interactive glass surfaces and displays are at the forefront of innovation and, while not yet ubiquitous, will become increasingly popular with users in the coming years. This is particularly true considering the very rapid commercial acceptance of products that utilize touchscreen technologies such as touchscreen phones, tablets, computers, televisions, and displays. As a result, users will have many more opportunities to interact with such interactive glass surfaces or other similar surfaces. For example, network-connected computers can display computer interfaces on a glass table for users sitting at the table during a meeting; glass walls can have interfaces that users can interact with to perform a variety of functions; sliding glass doors in homes can have computer displays that users can interact with, and patient bedrooms in hospitals can have glass walls that doctors can use to view medical information.
As interactive glass surfaces become more widespread, the chances of users or objects colliding with such glass surfaces will increase substantially. Unfortunately, glass surfaces can be quite dangerous to those who do not see them. A user that collides with an interactive glass surface can incur significant injuries or even cause the glass to shatter or malfunction. For example, if an interactive glass surface is used in a hospital, two doctors discussing and walking at the same time may collide with a clear interactive glass display. Also, kids running around a household may accidentally run into interactive glass doors or other displays and sustain serious injuries. Additionally, users may accidentally place inappropriate materials on a computer display that may ultimately damage the display. Furthermore, when a person is walking in the dark in the middle of the night to get a glass of water, the person may walk right into an interactive glass display. Although the future of interactive displays is exciting, there are many unique nuances associated with the use of interactive displays.
SUMMARY
A system and accompanying methods for providing awareness of an interactive surface are disclosed. The system may be configured to generate various types of notifications or perform other actions if a person or an object has a trajectory that indicates that the person or object will collide with an interactive surface. For example, various types of notifications may include, but are not limited to, one or more of adjusting the opacity of the interactive surface, presenting different types of messages on the glass surface, emitting sounds and vibrations, and displaying various types of images or colors on the glass surface. Notably, the trajectory of the person or object may be determined based on determining position and velocity by using one or more cameras, sensors, location positioning systems, and other systems and devices that can capture and process information about the person or the object. If the person or object continues on a trajectory to collide with the interactive surface, the notifications may increase in intensity. On the other hand, if the person or object changes its trajectory such that the person or object is no longer on a path to collide with the interactive surface, the system may cause the notifications to decrease in intensity or remove the notifications altogether.
The system for preventing a collision with an interactive surface may include a memory for storing instructions and a processor that is communicatively coupled to the interactive surface. The processor may execute the instructions to perform operations comprising receiving media content associated with an object that is within a range of the interactive surface. Additionally, the processor may be configured to detect a position and a velocity of the object that is in the range of the interactive surface. The processor may detect the position and the velocity based at least in part on the recorded media content. Also, the processor may determine if the object has a trajectory that would cause the object to collide with the interactive surface. The trajectory may be determined based on the position and the velocity of the object. Furthermore, the processor may generate a notification if the object is determined to have a trajectory that would cause the object to collide with the interactive surface.
In another embodiment, a method for providing awareness of an interactive surface is provided. The method may include receiving media content associated with an object that is within a range of the interactive surface. Additionally, the method may include determining a position and a velocity of the object that is in the range of the interactive surface based at least in part on the media content. A processor may be configured to determine the position and the velocity of the object by executing instructions stored in a memory. The method may also include determining if the object has a trajectory that would cause the object to collide with the interactive surface. The trajectory of the object may be determined based on the position and the velocity of the object. Furthermore, the method may include generating a notification if the object is determined to have the trajectory that would cause the object to collide with the interactive surface.
According to another exemplary embodiment, a tangible computer-readable medium comprising instructions for providing awareness of an interactive surface may be provided. The computer instructions, when loaded and executed by a processor, may cause the processor to perform operations including the following: receiving media content associated with an object that is within a range of an interactive surface; determining a position and a velocity of the object that is in the range of the interactive surface based at least in part on the media content; determining if the object has a trajectory that would cause the object to collide with the interactive surface, wherein the trajectory is determined based on the position and the velocity of the object; and generating a notification if the object is determined to have the trajectory that would cause the object to collide with the interactive surface.
These and other features of the system and methods are described in the following detailed description, drawings, and appended claims.

DETAILED DESCRIPTION OF THE INVENTION
A system 100 for providing awareness of an interactive surface 110 is disclosed in the present disclosure. The system 100 alerts a person to the presence of an interactive surface 110 to prevent a collision with the interactive surface 110. The system 100 for providing awareness of an interactive surface 110 may be configured to generate various types of notifications or perform other actions if a user or an object 105 has a trajectory that indicates that the user or object will collide with an interactive surface 110 or other surface. For example, various types of notifications may include, but are not limited to including, one or more of adjusting the opacity of the interactive surface 110, presenting different types of messages on or near the interactive surface 110, emitting sounds and vibrations from or around the interactive surface 110, or displaying various types of images or colors on or near the interactive surface 110.
The system 100 may determine the trajectory of the person or object 105 based on determining the person or object's position and velocity by using one or more image capture devices 120, sensors, location positioning systems, and other systems and devices that can retrieve or process information, or both, relating to the person or the object 105. If the person or object 105 continues on the trajectory to collide with the interactive surface 110, the system 100 may increase the intensity of the notifications or actions. However, if the person or object 105 adjusts its trajectory so that the person or object is no longer on a path to collide with the interactive surface 110, the system 100 may decrease the intensity of the notifications or even remove the notifications altogether. Also, the system 100 may utilize sensors to determine one or more of air movement, sounds, vibrations or other detectable information associated with the person or the object 105, and may generate notifications based on such information.
Although FIGS. 1-6 illustrate specific example configurations of the various components of the system 100, the system 100 may include any configuration of the components, which may include using a greater or lesser number of the components. For example, the system 100 may include multiple servers 150, multiple location determination devices 115, and multiple image capture devices 120. As another example, the system 100 may be configured to not include the air movement sensor 125, but may include the sound sensor 130 and the vibration sensor 135.
Object 105 in FIGS. 1A-2C is shown as being a person that is approaching the interactive surface 110. However, the object 105 is not limited to being a person, but may also be any animal or thing that could potentially collide with the interactive surface 110. Additionally, the object 105 may be anything that may be sensed by the various components of the system 100.
The interactive surface 110 may be any device that a user or potentially an animal could interact with and may be configured to display a wide range of notifications to users. As shown in FIGS. 1A-2C, the interactive surface 110 may be an interactive glass display, a computer, a mobile device, a tablet device, a wall display, an interactive table display, any interactive monitor or television display, any touchscreen device having a display, a plasma display, a liquid crystal display, a 3-dimensional (3-D), or any other device that has a display. In one embodiment, the interactive surface 110 may be an electrochromic device, a suspended particle device, a polymer dispersed liquid crystal device, mechanical smart windows, or a device having the capability of changing its opacity, color, visual appearance, or temperature, or a combination thereof.
The interactive surface 110 may include or otherwise be communicatively linked to one or more electronic processors 112 that may be configured to perform a variety of operations in the system 100. The electronic processors 112 may perform the operations in the system 100 or may direct various components in communication with the interactive surface 110 or other components of the system 100 to perform the operations, or both. For example, the electronic processors 112 may direct the electronic processors 116 of the location determination device 115 to determine position and velocity information for the object 105. As another example, the electronic processors 112 may direct the image capture device 120 to capture media content associated with the object 105. Notably, the interactive surface 110 may be configured to display colors, adjust its opacity, display images and messages, display user-interactive programs, emit sounds of various pitches, volumes, and timbres, emit vibrations, adjust its temperature, receive input from users, display outputs, or perform any computer operations by utilizing the electronic processor 112 or other means. Additionally, the interactive surface 110 may be communicatively linked to one or more of the location determination device 115, the image capture device 120, the air movement sensor 125, the sound sensor 130, the vibration sensor 135, the ultrasound device 137, the mobile device 140, the communications network 145, the server 150, and the database 155.
The location determination device 115 may be any device that may be utilized to determine a position or a velocity, or both, of the object 105, which, in FIGS. 1-6, is a person. The location determination device 115 may include or otherwise be communicatively linked to one or more electronic processors 116 that may be configured to perform a variety of operations. The electronic processors 116 may perform the operations in the system 100 or may direct various components in communication with location determination device 116 or other components of the system 100 to perform the operations, or both. The electronic processors 116 may be software, hardware, or a combination of hardware and software. The location determination device 115 may include a global positioning system, a device that determines location by triangulation, or any device that can determine the position or velocity of the object 105, or both. Notably, the location determination device 115 may be configured to determine a current position or a current velocity of the object 105, or both, with respect to the position of the interactive surface 110. Furthermore, the location determination device 115 may be communicatively linked with any of the components in the system 100 and can transmit data, such as the position or velocity data, or both together, with any other necessary information, to any of the components in the system 100. Although the location determination device 115 is illustratively shown on the interactive surface 110, the location determination device 115 may be placed anywhere that the location determination device 115 can effectively capture information associated with the object 105. In one embodiment, the location determination device 115 may be located in close proximity to or even within the interactive surface 110 itself.
The image capture device 120 of the system 100 may be a camera, such as, but not limited to, a video camera or other type of surveillance device that may be utilized to capture and record media content associated with the object 105. The media content can include visual content, audio content, content associated with vibrations that the object 105 makes, and other content. For example, if the object 105 is a person, as shown in FIGS. 1A-2C, the image capture device 120 can record video of the person and any sounds that the person makes when the person is in range of the interactive surface 110 or the system 100. The image capture device 120 may record sounds by utilizing a microphone, which may reside within the interactive surface 110 or in proximity to the interactive surface 110.
In one embodiment, the image capture device 120 may be configured to determine the position, size, and the velocity of the object 150 based on the media content that the image capture device 120 records. In another embodiment, the image capture device 120 may be able to generate a 3-D image that can be utilized to show where and how fast the object 105 is moving with respect to the interactive surface 110. Furthermore, the image capture device 120 may be communicatively linked with any of the components in the system 100. Although the image capture device 120 is illustratively shown above the interactive surface 110, the image capture device 120 may be placed anywhere that the image capture device 120 can effectively capture media content associated with the object 105. In an embodiment, the image capture device 120 may be a component of the interactive surface 110 itself, and may be positioned within the interactive surface 110 or outside of the interactive surface 110.
The air movement sensor 125 of the system 100 may be configured to detect changes in air movement, which may be generated by the object 105, that are in the general vicinity of the interactive surface 110. For example, if a person is running towards the interactive surface 110, the air movement sensor 125 can detect changes in air movement caused by the person's running. Additionally, the sound sensor 130 may be configured to detect changes in sound in the general area of the interactive surface 110 that may be caused by the object 105. For example, if a person is making sounds near the interactive surface 110, the sound sensor 103 can detect the sounds that the person makes. Furthermore, the vibration sensor 135 may be configured to detect changes in vibrations in the general area of the interactive surface 110 that may be caused by the object 105. For example, the vibrations that a person makes while walking or running towards the interactive surface 110 may be detected by the vibration sensor 135 and may be used by the system 100 to determine where the person is and how fast the person is moving.
One or more of the air movement sensor 125, the sound sensor 130, and the vibration sensor 135 may be configured to transmit detected information to any of the components of the system 100 and may be configured to include electronic processors. Also, the information detected by the air movement sensor 125, the sound sensor 130, and the vibration sensor 135 may be utilized in determining the position and velocity of the object 105. Although the air movement sensor 125, the sound sensor 130, and the vibration sensor 135 are illustratively shown on the interactive surface 110, the sensors may be placed anywhere that the sensors can effectively detect the information about the object 105.
In one embodiment, the system 100 may also include an ultrasound device 137, which can be configured to emit an ultrasonic sound in the direction of the object 105. Once the ultrasonic sound is emitted, an echo may be returned from the object 105 based on the ultrasonic sound. The echo may be utilized by the system 100 to determine various information about the object 105 such as, but not limited to, the size, shape, position, and velocity of the object 105. Additionally, the echo may be utilized by the system 100 to generate an image, such as a 3-D image of the object 105 so that the interactive surface 110 can determine what is approaching it and display any necessary warning notifications.
The mobile device 140 may be cellular telephone, a tablet, a personal computer, or any other similar device that may be utilized by a person that is approaching the interactive surface 110. Notably, the mobile device 140 may be communicatively linked with any of the components in the system 100 and may transmit position or velocity data, or both, associated with the object 105 to the interactive surface 110 or other components in the system 100. For example, if the mobile device 140 is a cellular phone with a global positioning system (GPS), then position information, identification information, velocity information, or other types of information associated with the mobile device 140 or the person 105, or both, may be transmitted to the system 100 by the GPS. Additionally, the mobile device 140 may utilize triangulation or other location determination mechanisms to determine the position and velocity of the objection 105. The information transmitted to the system 100 may be utilized in determining a trajectory of the object 105 with respect to the interactive surface 110.
The communications network 145 may be any other suitable network that may be utilized to allow the various components of the system 100 to communicate with one another. For instance, the communications network 145 may be a wireless network, an ethernet network, a satellite network, a broadband network, a cellular network, a private network, a cable network, the Internet, or any other network. The server 150 may include an electronic processor and may be configured to handle any necessary processing for carrying out the various operative functions of the system 100. For example, the server 150 may receive data from the interactive surface 110, the location determination device 115, the image capture device 120, the air movement sensor 125, the sound sensor 130, the vibration sensor 135, the mobile device 140, the communications network 145, the ultrasound device 137, and the database 155 to determine the precise location of the object 105. In one embodiment, any of the electronic processors disclosed herein may perform the operations in the system 100 or may direct various components in communication with the components of the system 100 to perform the operations, or both. Additionally, the server 150 may be configured to transmit signals to the interactive surface 110 so that the interactive surface 110 can display notifications. As an example, if the system 100 determines that a person is about to collide with the interactive surface 110, the server 150 may send a signal to the interactive surface to display a message on the interactive surface 110 that can warn the person of the impending collision. Furthermore, any and all data that traverses the system 100 may be stored in the database 155.
Operatively, the system 100 may be configured to provide awareness of the interactive surface 110 in a variety of ways. In a first example scenario, which is illustrated in FIGS. 1A-1C, an object 105 (in this case a person) is approaching the interactive surface 110. In this example, the interactive surface 110 is a large interactive glass display. In FIG. 1A, for example, the person is illustratively shown at a location far away from the interactive surface 110. One or more of the location determination device 115, the image capture device 120, the various sensors 125, 130, and 135, the ultrasound device 137, the mobile device 140, the communications network 145, the server 150, and the database 155, can all work in concert with one another to determine the person's position and velocity with respect to the interactive surface 110. Notably, not all of these devices are required to determine the position and velocity of the person, but rather any subset of the devices in the system 100 may be utilized to determine the person's position and velocity.
Once the position and velocity of the person are determined, the system 100, via server 150 or any other device in the system 100, can determine a trajectory of the person with respect to the interactive surface 110. If the trajectory indicates that a collision will occur, the system 100 may send a signal to the interactive surface 110 to display or emit a notification that can be perceived by the person. The notifications may include, but are not limited to including, a displayed image or message, a change in color of the interactive surface 110, emitted sounds and vibrations, or a change in the opacity of the interactive surface 110. In FIG. 1A, the person is far enough away from the interactive surface 110 that the system 100 does not cause the interactive surface 110 to generate a notification and the interactive surface 110 can remain in a transparent state.
In FIG. 1B, however, the person is shown at a location that is closer to the interactive surface 110 than the person is in FIG. 1A. The various devices in the system 100 may determine that the person is located at a position and is moving at a velocity such that the person may eventually collide with the interface surface 110. If the person is determined to be moving on a trajectory to eventually collide with the interface surface 110 based on his or her position or velocity, then system 100 may generate a notification and transmit the notification to the interface surface 110. In one embodiment, the notification may be a message such as “Warning! Nearing Glass Surface!,” or another message that can notify the person of the presence of the interface surface 110. Additionally, the system 100 can cause the interface surface 110 to emit sounds and vibrations to notify the person of the presence of the interface surface 110 as well. At this point, the person may either change his or her trajectory based on the notifications displayed or emitted by the interface surface 110, or may continue to proceed on the trajectory towards the interface surface 110. If the system determines that the person stops moving, or moves in an alternate trajectory that would not cause the person to collide with the interface surface 110, the system 100 may remove any displayed notifications or cause any emitted warning sounds and vibrations to stop.
However, if the person continues to move on the trajectory to collide with the interface surface 110 as illustrated in FIG. 1C, then system 100 may transmit a signal to the interface surface 110 to display a more intense message such as “Warning! You Are About To Collide With This Glass Surface!,” or another message that can urgently notify the person of the presence of the interface surface 110. Additionally, as shown in FIG. 1C, the system 100 can cause the interface surface 110 to emit sounds and vibrations of increased intensity to notify the person of the presence of the interface surface 110. Hopefully, after sensing or seeing the notifications of increased intensity, the person will change their trajectory to avoid a collision with the interface surface 110. If, however, the person was merely rushing to use the interface surface 110, and the person eventually slows down to a point where the system 100 no longer considers the person to be on a trajectory to collide with the interface surface 110, the interface surface 110 can either reduce the intensity of the notifications or remove the notifications altogether. In one embodiment, the interface surface 110 can display a program that the person may want to use or display instructions to teach the user how to use the interface surface 110.
In another example scenario, which is illustrated in FIGS. 2A-2C, an object 105, which is shown as being a person, is approaching the interactive surface 110, which in this case is a large interactive glass display. In FIG. 2A, the person is shown at a location far from the interactive surface 110. As in the previous example, the various components of the system 100 can all work in concert together to determine the person's position and velocity with respect to the interactive surface 110. However, as mentioned above, not all of the devices in the system 100 are required to determine the position and velocity of the person, but rather any subset of the devices in the system 100 may be utilized to determine the person's position and velocity. Once the position and velocity of the person are determined, the system 100, via server 150 or any other device in the system 100, can determine the trajectory of the person with respect to the interactive surface 110. If the trajectory indicates that a collision will occur, the system 100 may send a signal to the interactive surface 110 to display or emit a notification that can be perceived by the person. In FIG. 2A, the person has been determined to be far enough away from the interactive surface 110 that the system 100 does not cause the interactive surface 110 to generate a notification. As a result, the interactive surface 110 remains in a transparent state.
In FIG. 2B, however, the person is shown at a location that is closer to the interactive surface 110 than the person is in FIG. 2A and closer than a threshold distance. When the person proceeds closer than the threshold distance, the system 100 may determine that the person has a position and velocity such that the person may collide with the interface surface 110. If the person is determined to be moving on a trajectory to eventually collide with the interface surface 110 based on his or her position or velocity, then system 100 may transmit a signal to the interface surface 110 to adjust its opacity or color so that the system 100 that can alert the person of the presence of the interface surface 110. As shown in FIG. 2B, the interface surface 110 is more opaque than the interface surface 110 illustrated in FIG. 2A. Alternatively or additionally, the system 100 can cause the interface surface 110 to emit sounds or vibrations, or both, to notify the person of the location of the interface surface 110. Upon sensing the notifications from the system 100, the person may either change his or her trajectory or may continue to proceed on the trajectory towards the interface surface 110. If the system determines that the person is no longer on a trajectory to collide with the interface surface 110, the system 100 may cause the interface surface 110 to remove or reduce any notifications. However, if the person continues to move on the trajectory to collide with the interface surface 110 as illustrated in FIG. 2C, then the system 100 may transmit a signal to the interface surface 110 to increase the opacity of the interface surface 110 to further notify the person of the presence of the interface surface 110.
In one embodiment, the interface surface 110 may be given a signal by the system 100 to display a darker or brighter color on the interactive surface 110. For instance, as shown in FIG. 2C, the interface surface 110 is more opaque than the interface surface 110 illustrated in FIG. 2B. Additionally, the system 100 can cause the interface surface 110 to emit sounds or vibrations, or both, of increased intensity to notify the person of the interface surface 110. Hopefully, after noticing the notifications of increased intensity, the person will change their trajectory to avoid colliding with the interface surface 110. However, if the person was merely rushing to use the interface surface 110, and the person eventually slows down to a point where the system 100 determines that the person is not on a trajectory to collide with the interface surface 110, the interface surface 110 can either reduce the intensity of the notifications or remove the notifications. In one embodiment, the interface surface 110 can display a program that the person may want to use or even display instructions that can teach the user how to use the interface surface 110.
An exemplary method 300 for providing awareness of an interactive surface 110 as shown in FIG. 3 involves a situation where a child is running around a family home. The method 300 may include, at step 305, having a child running around his family's house. While the child is running around the house, the system 100 may determine, at step 310, whether the child is in the range of the interactive surface 110, which in this case may be an interactive glass display. At step 315, the system 100 may determine that the child is on a trajectory to collide with the interactive surface 110. Once the system 100 determines that the child is on the trajectory to collide with the interactive surface 110, the system 100 can transmit a signal to the interactive surface 110 to cause the interactive surface 110 to increase its opacity. Alternatively or additionally to sending a signal to increase opacity, the system 100 can send a signal to the interactive surface 110 to generate and vibrate a low-pitch tone at step 325. At step 330 of the method 300, the child can see or hear, or both, the interactive surface 110 based on the increased opacity and the low-pitch tone. Once the child sees or hears, or both, the interactive surface 110, the child can change his trajectory so that he will no longer be on course to collide with the interactive surface 110 at step 335. At step 340, the system 100 can determine that the child is on a new trajectory that would not cause a collision with the interactive surface 110. At step 345, the system 100 can send signals to the interactive surface 110 become transparent once again and to stop vibrating the tone.
Another exemplary method 400 for providing awareness of an interactive surface 110 (in this case a glass display), as shown in FIG. 4, involves a situation where a child does not take the first warning from the interactive surface 110. The method 400 may include, at step 405, having the child running around his family's house as in the previous example. While the child is running around the house, the system 100 may determine, at step 410, the child's movement information, such as his position, velocity, and trajectory. At step 415, the system 100 may determine that the child is getting too close to the interactive surface 110. As a result, the method 400 may include having the system 100 send a signal to the interactive surface 110 to increase its opacity such that the interactive surface 110 is 20% white at step 420. At step 425, the system 100 can cause the interface surface 110 to emit a 700 hertz (Hz) vibration.
At step 430, the system 100 can determine that, despite the initial notifications, the child is getting even closer to the interactive surface 110. Now, the system 100 can send another signal to the interactive surface 110 to increase its opacity such that the interactive surface 110 is now 40% white at step 435. Additionally, at step 440, the system 100 can cause the interface surface 110 to adjust the 700 Hz vibration to a 1400 Hz vibration. At this point, the child may see or hear, or both, the interactive surface 110 at step 445. At step 450, the system 100 can determine that a collision with the interactive surface 110 has been avoided because the child has changed his trajectory. At step 455, the child can run elsewhere and the system 100 can determine the child's new position, velocity, and trajectory and find that the child is no longer at risk of a collision. At step 460, the system 100 can transmit a signal to the interactive surface 110 to return to a clear or transparent state. Finally, the system 100 can transmit a signal to the interactive surface 110 to stop emitting vibrations at step 465.
In yet another an exemplary method 500 for providing awareness of an interactive surface 110, as shown in FIG. 5, the method 500 may include, at step 502, recording media content associated with an object 105 that is in the range of an interactive surface 110. The media content can be sound content, visual content, or vibrations, any combination thereof, or any other content. The media content may be recorded, for example, by the image capture device 120 or other appropriate device. At step 504, the method 500 may include determining a position and a velocity of the object 105 based on the media content or on any of the information gathered by any of the components in the system 100, or any combination thereof. The position and the velocity, for example, may be determined by the location determination device 115, the interactive surface 110, the server 150, the computer system 600, any combination thereof, or other appropriate device. The method 500 may include, at step 506, determining if the object 105 has a trajectory that would cause the object to collide with the interactive surface 110 based on the position and velocity of the objection 105. The trajectory may also be determined based on sensed vibrations, sounds, images, or other information gathered by the components of the system 100. In one embodiment, the trajectory may be determined by the location determination device 115, the interactive surface 110, the server 150, the computer system 600, any combination thereof, or other appropriate device.
At step 508, if the object 105 is determined not to be on a trajectory to collide with the interactive surface 110, then the method can return to step 502 or the method can conclude. However, if the object 105 is determined to be on a trajectory to collide with the interactive surface 110, the method 500 may include generating a notification on or near the interactive surface 110 to indicate the location of the interactive service 110 at step 510 via the location determination device 115, the interactive surface 110, the server 150, the computer system 600, any combination thereof, or other appropriate device. At step 512, the method 500 may include determining if the object 105 is still on the trajectory to collide with the interactive surface 110 despite the notifications. Step 512 may be performed by the location determination device 115, the interactive surface 110, the server 150, the computer system 600, any combination thereof, or other appropriate device. If the object 105 is no longer on course to collide with the interactive surface after the initial notifications, the method 500 may include reducing or removing the notifications from or around the interface surface 110 at step 514. However, if the object 105 is still on course for a collision with the interface surface 110, then the method 500 may include increasing the intensity or number of notifications, or both, so that the object 105 hopefully changes its trajectory at step 516. In one embodiment, steps 514 and 516 may be performed by the interactive surface 110, the server 150, the computer system 600, any combination thereof, or other appropriate device.
In one embodiment, the system 100 and methods described herein may include presenting the notifications only on a portion of the interactive surface 110. For instance, while notifications are presented on some portions, other portions of the interface surface 110 can remain in normal operational mode. In another embodiment, the systems and methods may include enabling a person to use the interactive surface 110 as a whiteboard. For example, if the system 100 causes the interactive surface 110 to become opaque as a notification to a person approaching the interactive surface 110, the opaque portion may be used as a whiteboard by the person. In an embodiment, the trajectory calculated by the system 100 may be a predicted path that the person or object 105 may be determined to be following.
In another embodiment, the system 100 and methods may include providing a specific sequence or pattern of notifications based on the situation that presents itself. For example, the system 100 may cause the interactive surface 110 to emit a specific low sound, multi-pulse sequence that can indicate when the interactive surface 110 can be utilized as a computer display, whiteboard, or for certain other purposes. In another embodiment, the system 100 and methods may include having the interactive surface 110 visually or orally identify its functions to users and any data to which it has access. In another embodiment, the system 100 and methods can utilize infrared technology, motion detectors, laser detectors, or any other type of detector to assist in determine a position, velocity, or other information associated with an object 105. In another embodiment, the method 500 may include determining the positions and velocities of multiple objects 105. Multiple trajectories may be determined either for a single object 104 or for multiple objects 105 and notifications may be generated so that they are tailored to each object 105 that is approaching the interactive interface. It is important to note that the methods described above may incorporate any of the functionality, devices, or features of the systems described above, or otherwise, and are not intended to be limited to the description or examples provided herein.
