## Title
System and method for communication using ambient communication devices

## Abstract

Interactive communication devices in communication with a central server support ambient communications between two or more remotely located users. Each device has embedded sensors, lights, and speakers. The sensors allow the device to sense ‘outgoing’ interaction (e.g., a squeeze or hug), and the lights and speakers allow the device to demonstrate ‘incoming’ interaction. A central device is activated when someone interacts with any of the other devices within the network. The other devices in the network—the peripheral devices—are activated both when the interaction originates from the central device as well as from the other peripheral devices. When the server determines that a user has interacted with one of the devices, messages are sent to other devices in the network to reflect the user interaction. The communication devices allow the users in the network to send messages to each other by simply squeezing their respective devices.

## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to U.S. Provisional Application Ser. No. 61/173,997, filed Apr. 30, 2009, titled SYSTEM AND METHOD FOR COMMUNICATION USING AMBIENT COMMUNICATION DEVICES, the content of which is incorporated by reference as if fully recited herein.


FIELD OF THE INVENTION
The present invention relates generally to computerized communication systems and methods. In particular, the disclosed embodiments relate to interactive communication devices that support ambient communications between remotely located users.
BACKGROUND OF THE INVENTION
It is common today for the generations of a family to live in different neighborhoods, cities, states, and even countries. Similarly, an increasing number of divorces as well as job-related travel requirements cause family members to be separated for varying periods of time. Although staying connected across distances is facilitated with the use of mobile phones and computers, there are practical limitations to the types of communications and interactions that family members can have using these devices. The devices require users to have a certain level of physical as well as mental dexterity. The family members that use them must be able to dial, type, talk, etc. As a result, older family members may have difficulty using them and very young family members may not be able to use them at all.
Furthermore, because of the complexity, overhead, and intrusiveness of the devices as well as the need for privacy associated with using the devices, and in some cases costs, many families limit their use of the devices to situations in which they need to communicate an important message or a long message. When two family members connect by phone or computer, they may engage in a series of communications and remain engaged for a longer period of time than expected. For very busy families, they may intentionally avoid initiating a communication with another family for fear of becoming occupied in ongoing communications longer than they intended. In other words, they may avoid simply saying “hello” to each other for fear that a longer sequence of communications will ensue. In other situations where privacy cannot be assured, family members may simply choose not to establish communication. As a result, communication devices that are capable of supporting and typically used for long and in-depth conversations are not used for simple, short communications such as saying “hello” or “I'm thinking of you.”
For a variety of reasons, family members that are separated from one another have or take few opportunities to simply say “hello” or “I'm thinking of you” to one another. There is a need for communication devices that support short and simple interactions between family members in different households. There is a need for communication devices that are easy to use, especially for very old and very young family members that may have difficulty using conventional communication devices such as telephones and computers. Finally, there is a need for communication devices that support ambient communications between family members in different households.
SUMMARY OF THE INVENTION
An interactive communication device in communication with a central communication server supports short, simple, ambient communications to and between two or more remotely located users. A computerized system connects the devices and allows multiple users to communicate with each other in an ambient way using the interactive devices. In an example embodiment, the communication devices are a set of interactive stuffed bears. In this embodiment, the computerized system is centered on a one-to-many interaction between a small child and several close family members or friends. Each bear has embedded sensors, lights, and speakers. The sensors allow the bear to sense ‘outgoing’ interaction, and the lights and speakers allow the bear to demonstrate ‘incoming’ interaction. The child's bear—the central bear—is activated when someone interacts with any of the other bears within the network. The other bears in the network—the peripheral bears—are activated both when the interaction originates from the central bear as well as from the other peripheral bears. In an example embodiment, peripheral bear interactions are more subtle than central bear activations to distinguish them from central bear activations.
In an example embodiment, each bear is equipped with a pressure sensor that measures a “squeeze,” “hug,” or “touch.” One bear—the central bear—has the ability to provide two kinds of feedback by different actuators: sound and light. The two types of feedback allow each peripheral bear to trigger a unique or different effect in the central bear. The peripheral bears also have both feedback mechanisms to show a different reaction when the central bear has been squeezed, hugged, or touched. The communication devices allow the users in the network to send short and simple “hello” or “I'm thinking of you” messages by simply physically interacting with a bear or similar type of item equipped with the sensors, actuators, and electronics.

DETAILED DESCRIPTION
The present invention comprises a computerized network of ambient communication devices. In an example embodiment, the communication devices are stuffed bears that are equipped for communication via the network. In addition to bears and other animals, any item that can be equipped with the sensors and actuators may be used in the communication network in order to implement such tangible interaction and interface. Such items include dolls, pillows, balls, and similar types of toys that may be squeezed, hugged, or touched.
Each bear is equipped with an embedded pressure sensor that measures a “squeeze,” “hug,” or “touch.” One bear is designated as the central bear and other bears are designated as peripheral bears. The central bear has the ability to provide two or more kinds of feedback (such as a sound, vibration, or glowing element) while the peripheral bears have one feedback mechanism. When a user interacts with the central bear, the feedback mechanism (actuators) in the peripheral bears is triggered. When users of the peripheral bears respond, the different feedback mechanisms in the central bear are triggered to distinguish the feedback from each peripheral bear. Each peripheral bear may trigger a different effect in the central bear.
In an example embodiment, each bear or other ambient communication device is equipped with the following components. Referring to FIG. 1, a sample ambient communication device 100 in the form of a bear is shown.

Referring to FIG. 2, a diagram of a computer system architecture according to an example embodiment is shown. In an example embodiment, each bear is equipped with a microcontroller, a WiFi serial bridge, a tactile sensor, a light or other glowing element, and a speaker 200. The bears are distributed to users that are located remotely from one another (i.e., in different households). For example, a central bear 202 may be given to a child and the peripheral bears 212, 218 may be given the child's maternal grandparents and paternal grandparents, respectively. Each bear 202, 212, 218 communicates via a respective base station 204, 214, 220 and home network router 206, 216, 222. Communications are routed through the Internet 208 to a central server 210 that manages the communications between the devices by sending appropriate messages to each device.
A software application at the server 210 controls the triggers and responses at the bears 202, 212, 218. In an example embodiment, one bear is designated at the server to be the “central” bear while the other bears in the network are “peripheral” bears. The bears may be used to facilitate communications between members of a family. The ambient communication devices are particularly useful in facilitating communications between a grandchild and grandparents, especially if the grandchild is so young as to be unable to use a telephone or computer without assistance from an adult.
In an example embodiment, the communication server runs on a Mac in a MAMP (Mac, Apache, MySQL, PHP) structure. In the example embodiment, the bears communicate on an 802.11b network over TCP/IP with the central communication server that accepts and dispatches messages. Bears can poll the server asynchronously using HTTP, with arbitrary frequency, to report interactions and collect feedback messages (e.g., sound and light ASCII encoded messages). Interaction messages (or tactile input messages) are sent to the communication server by the bears using HTTP-get-requests, and then the communication server, according to rules defined in PHP server scripts, prepares display output messages for feedback (e.g., sound and light messages). A MySQL database on the server stores the feedback messages or display output messages (e.g., sound and light messages) for each bear until it polls the server HTTP to retrieve them. Once a bear has polled the server and received any waiting messages, the messages are cleared from the database.
Referring to FIG. 3, a diagram illustrating various communication scenarios is shown. In the scenarios, the central bear (Bear 1) is controlled by a child, a first peripheral bear (Bear 2) is controlled by the child's maternal grandmother or grandfather, and a second peripheral bear (Bear 3) is controlled by the child's paternal grandmother or grandfather.

As indicated in the scenarios, each peripheral bear (i.e., each grandparent's bear) responds when the grandchild interacts with the central bear. When each grandparent responds by interacting with a peripheral bear (e.g., squeezing or hugging), the central bear responds with a communication that uniquely identifies the peripheral bear (i.e., the respective grandparent). For example, the central bear may play a sound when the first peripheral bear is squeezed and blink a light when the second peripheral bear is squeezed. The sound may be a recording of a voice, music, etc. In addition, each peripheral bear responds when the other peripheral bear is squeezed. The response at the non-initiating peripheral bear may be subtle so that the user recognizes that the communication was initiated at a peripheral bear rather than the central bear. For example, the response may be a short, soft display of a sound or light.
In other embodiments of the invention, the ambient communication devices may be configured to provide various types of sensory feedback including vibrations or other forms of tactile feedback as well as visual, aural, and vocal feedback. Various combinations and patterns of feedback may be used to allow individuals in the network to distinguish communications received from the different users. User interactions with the device may be vocal in addition to tactile. A variety of input or interaction and output or feedback messages may be supported. The ambient communication devices may also take on a variety of forms, shapes, sizes, appearances, etc. depending upon the needs of the users. One of skill in the art would recognize that many different types of ambient communication devices could be designed and configured to provide the described communication features and functionality.
The disclosed ambient communication devices allow remotely located family members to spontaneously “touch” one another. When a user's bear plays a sound, displays a light, etc., the user knows that another family member is sending a squeeze or hug. The user receiving the “squeeze,” “hug,” or “touch” through the device can return a “squeeze,” “hug,” or “touch” to the sender. The invention allows family members and friends to communicate with one another in a new and different way.
While certain embodiments of the present invention are described in detail above, the scope of the invention is not to be considered limited by such disclosure, and modifications are possible without departing from the spirit of the invention as evidenced by the claims. For example, specific features of the ambient communication devices may be modified in a variety of ways but still allow for remote communications as described. Other aspects of the architecture and overall communication model may be varied and fall within the scope of the claimed invention. One skilled in the art would recognize that such modifications are possible without departing from the scope of the claimed invention.
