## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an interactive educational system for elementary school age children. More particularly, the present invention is an interactive learning tool for collecting and displaying scientific data and presenting that data to children age 5 and over in such manner to encourage the child to learn more about the scientific principle involved.
2. Description of Related Art
Current educational teaching systems and youth science experiment kits require adult help to set up the experimental activity and expect the children to be, at a minimum, technology savvy. While there are systems available for collecting data and transmitting the data to another location and there are gaming systems available that provide entertainment for children, there has been little effort made to utilize technology to teach elementary school age children.
Educational learning toys enhance intellectual, social, and/or physical development and are designed to encourage reasonable development milestones within appropriate age groups. There is little doubt that education tools and toys play a constructive role in the modern education curriculum. Interactive electronic toys such as robots and the like are frequently used as part of the curriculum in high school and post-secondary education. Existing electronic learning toys for elementary aged kids are designed to aid a child's educational growth in such areas as spelling, vocabulary, mathematics and language. These interactive learning toys include electronic laptops, video games and other educational tools.
It is also known that children respond to tools that allow them to design and build things, and increase participation or demonstration in hands-on learning related to science, technology, engineering, mathematics and entrepreneurship.
However, there remains a need for interactive educational tools for use in the science and technology areas that are directed to children aged 5 and over. It has been stated that a child's engagement in scientific inquiry gives them the opportunity to receive accurate feedback directly from the outcomes of their own inquiry. The system of the present invention aids in providing that learning opportunity.
SUMMARY OF THE INVENTION
It is therefore the general object of the present invention to provide an easy to use learning tool for teaching elementary school age children scientific principles relating to phenomena, such as temperature, sound, light, gravity and the like.
The interactive educational system of the present invention has a base module that houses a complement of sensors and end effectors and an interactive application hosted on a smart device such as devices like a tablet, cell phone, or laptop. The base module has a housing with an outer configuration that is appealing to children. The housing contains the electronic circuitry that gathers data from the sensors and effectors within the housing and provides the information in a display on the base module. The base module transmits state information and sensor data wirelessly to a smart device. Multiple base units can communicate with the smart device and allow the smart device to collaboratively control and display multiple base units' data.
The housing of the base module may include retaining sockets used to retain accessories. The sockets preferably contain magnets in the bottom of each socket to attract and retain the arms and/or legs. The housing may be made of plastic, metal, or similar material and over-molded with a silicone-like material on the common body to seal the circuitry inside the housing. Over-molding provides a soft, durable body, and allows for custom colors and features for each modular design. The over-molded features can be changed for each base module design contemplated. The configuration of the housing of the base module may take a variety of shapes and sizes to form characters that are appealing to children.
The control circuitry includes a power supply and a voltage regulator which powers a controller. The controller is preferably an integrated circuit containing a processor core, memory, and programmable input/output peripherals. Data from the sensors and end effectors are sent to the controller where they can be transmitted to a smart device and presented on a base module's video display.
The base module has a wireless transceiver. The transceiver can receive data from a smart device to change the base module's mode of operation and articulate an end effector. The base module wirelessly sends sensor data, effector data, and base module state information to the smart device where the smart device can complete further processing on the data, store the data, or transmit it to the internet cloud. Different complements of sensors are included in the base modules such as a temperature sensor, a light sensor, sound pressure sensor, and an accelerometer to name a few. The base modules include a complement of end effectors. Some examples of end effectors include lights, buzzers, linear actuators, and rotary actuators to name a few. Examples of light and audio feedback responses include flashing LEDs and playing the different tones and tunes with the buzzer.
The smart device includes a common transceiver to talk wirelessly with the base modules. It is conceived that the smart device can come in many forms; for example, the smart device may be a fun toy form factor like the base modules, a dongle that plugs into a computer, a smart phone, a tablet, or any variation thereof. The smart device includes an application that allows the user to easily pair one or more base modules with the smart device, display state data and sensor data of the base module's connected to it, control the mode and state information of the base modules, and allow for collaborative programming of the base modules. For example, if a base module's sensor exceeds a preset limit set in the smart device's application, it may cause one or more of the base modules to make a mode change, play a tune, or light up. It is also conceived that the smart device transmitting the base module network information through the internet can allow kids to collaboratively control base modules linked to other smart devices.
Other objects, features, and advantages of the invention will be apparent to those skilled in the art from the following detailed description taken in conjunction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT(S)
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to the elements throughout.
The interactive educational system of the present invention is a learning tool for elementary school age children. Rule-based controls allow the interactive educational system to provide a network to work together to become, for example, an alarm clock that beeps the base module of the interactive educational system that is placed, for example, in a child's room when another base module of interactive educational system with a motion sensor present has been placed on a dog's collar is reading movement. In addition, other base modules may include a light sensor that can be set to alert its base module or multiple base modules when the light intensity has reached a predetermined level. Another example of interactive educational system is that the system can become a sibling intrusion alert that makes all the base module components play a sound and light up when the base module with a motion sensor senses movement in the child's room. A smart device hosts an interactive application for configuring and reporting the sensors and effectors of the base modules. Programs and settings for the base modules, once set within the application, are transmitted wirelessly to the base modules. Base module sensors and end effectors data is transmitted along with base module state information to the interactive application. The base module comes in a fully assembled operational state for simple use.
The interactive educational system of the present invention is a smart collaborative sensor system and science experimental pal for children aged 5 and over. The interactive educational system includes a smart device with an interactive application and one or more base modules. The base modules house single or multiple sensors (e.g., acceleration, temperature, sound and the like) and one or more end effectors (e.g., lights, buzzer, lift mechanism, rotational turn mechanism, and the like). The base modules can wirelessly communicate with a smart device and to other base modules. One example of the base module 100 is shown in FIG. 1 in which the base module has a housing 102 with an outer configuration in the shape of a character that is appealing to children. The housing 102 contains the electronic control circuitry 120, shown more clearly in FIG. 4 that gathers data from the internal sensors, said data being associated with a scientific principle for teaching said principle to said children. The data gathered can be presented to the user as shown in display 104 in FIG. 1 on the front of the character housing the base module 100. The data is also transmitted wirelessly to the receiving smart device 800 where it is displayed in the interactive application 700, which is shown more clearly in FIG. 10.
In the embodiment shown in FIGS. 1-3, the housing 102 of base module 100 includes retaining sockets 106, 108. The sockets 106, 108 may be seen more clearly in FIG. 3 and which may be used to retain arms, such as the flexible arms shown in FIG. 5B. In addition, housing 102 may have retaining sockets 110 and 112 which may be used to retain legs for the base module in place, such as shown in FIG. 6B. The sockets preferably contain magnets in the bottom of each socket to attract and retain magnets attached to the arms and/or legs of the character. While the sockets are shown protruding from the housing, the sockets may be conformal, below the outer surface, or in other orientations.
The housing 102 may be made of plastic, silicon, or similar material and over-molded by a silicon-like material on the common body to seal it (e.g., make it waterproof). Over-molding provides a soft, durable body, and allows for custom colors and features for each modular design. The over-molded features can be changed for each modular design contemplated. As shown in FIGS. 1-3, the base module 100 has decorative feature such as molded hair 105. In the base module 100 shown in FIG. 1 the digital display is reading 70° F. which indicates the temperature emanating from the base modules present surroundings.
The control circuitry 120 of the interactive educational system of the present invention is shown in FIG. 4. The control circuitry 120 includes a power supply. In the example shown in FIG. 4 the power supply comprises a 3V coin cell battery 122 and a DC/DC power controller/conditioner 124 that regulates the voltage to a controller 126.
The controller 126 is preferably an integrated circuit containing a processor core, memory, and programmable input/output peripherals operatively connected to a wireless transceiver 134. Preferably, the MCU will be an 8-bit AVR microcontroller, such as those supplied by Atmel®.
Data from the base module's 100 sensor group 140 is displayed on the video display 104 from information passed to the controller 126. The video display is preferably a reflective LCD, graphic on some models and alphanumeric on others. In the case of graphics, they would be built into the controller. Alphanumeric displays require an I/O expander or similar. Other graphic displays, such as, flexible electronic ink displays or other low power consumption screens could alternatively be used. LEDs 131 mounted in or reflected through the housing 102 provide feedback to user. The base module 100 sensor data may also be stored in the controller 126 or EEPROM 144 with time data for later download, graphing and analysis. The data is wirelessly communicated to the internet or an interactive application 700 of a PC or mobile device, also known as a smart device 800.
Alternatively, or in conjunction with the visual display 104 and the LED lights 131, audio responses may be provided. For example, the audio 128 may be a speaker capable of playing different tones and tunes. A microphone 130 and other sensor group 140 components will be selectively populated, depending on the particular base module. A reed switch 132 is connected to the controller 126 that allows the user to interact with the base module 100 of the educational system by opening and closing the switch with a magnetic field. It is conceived that some base modules 100 may contain additional mechanical effectors 151, 152 (e.g., rotary actuators, linear actuators, and other such devices) that respond when conditions are met or commands are sent wirelessly from the smart device to the specific base module.
The base module 100 has a wireless transceiver 134 for sending sensor/effector data and state information to the smart device and receiving commands and programs from the smart device. Preferably, the wireless transceiver 134 is housed in the base module 100 and connected through a bus 136 where the data is sent to or received from the controller 126.
The sensor group 140 are a selectively populated group of sensors used to gather and monitor scientific data and send the scientific data to controller 126 through the bus 136 in the circuitry of base module 120. The sensor group 140 may have only one sensor, e.g., a temperature sensor 145 but will preferably have several sensors such as light sensor 148, and accelerometer 147. Other sensors optionally include; sound, motion, rate, GPS, magnetic field, moisture, distance, color, humidity, barometric pressure, force, proximity, radiation, current, biometrics, camera, voltage, displacement, and capacitive touch. These sensors will likely be digital sensors capable of communicating via I2C or SPI but some may be analog and routed through an analog-to-digital converter. The data from the sensor may be stored in EEPROM 144 and sent to the wireless transceiver 134 or displayed on the sensor in display 142. The wireless transceiver 134 is preferably a Bluetooth low energy module. In operation, the child may, in this example, place a base module 100 populated with the temperature sensor 145 in a refrigerator and the sensor will gather data on the temperature inside the refrigerator and send that data to another base module 100 and the smart device 800 with the interactive application 700 for display.
The configuration of the base module 100 may take many shapes and forms such as, for example, those shown in FIGS. 5-8.

The base module 500 has a housing 502 having sockets 506, 508 for arms and a digital display 504. In the embodiment in FIG. 8, the base module 500 is similar to that of FIG. 1 except that the housing 502 is a unitary construction in which the legs 517, 518 are built into the module as shown in FIG. 8.
FIG. 9 represents a variation on the embodiment of FIG. 1 of the base module of the interactive education system of the present invention. The base module 600, has a housing 602 with a graphical display 604. Custom graphics, sensor data, effector states, time data, and system modes are some of the items that may be shown on the graphical display 604. The base module 600 has bendable legs 617, 618 that include a wire structure molded over by silicon to allow the legs to be formed in many shapes or wrapped around items to secure the base module 600. The feet 619, 620 are magnetic suction cups that allow the feet to be secured to each other so they can be clasped to objects like a collar, backpack, or handlebars to name a few, or surfaces that are smooth or magnetic.
