1. Technical Field
Embodiments of the present disclosure relate to an electronic toy, and more particularly to a system and a method for displaying an emotion of an electronic toy using an emotion unit.
2. Related Art
Nowadays, many electronic toys are intelligent. Electronic toys can walk, speak, and display different emotions by obtaining ambient information (for example, light, sound, temperature, and actions) and internal information (for example, power supply, and body temperature). In one example, U.S. Pat. No. 6,415,203, U.S. Pat. No. 6,442,450, and U.S. Pat. No. 6,667,593 disclose toys capable of changing their own emotion by apperceiving external or/and internal information.
In another example, toys can display different emotions by emitting different colored lights. For instance, a toy named “iCat” is produced by the Japanese company, Segway. The iCat employs the use of seven pieces of triple-color LEDs positioned on a face of the iCat in order to emit different colors corresponding to different emotions.
The iCat only emits a simple color by one or more triple-color LEDs to display one kind of emotion at one time. The iCat cannot change the color of the triple-color LEDs during an action according to the one kind of emotion.
SUMMARYIn view of the foregoing disadvantages inherent in the known electronic toys present before, the present invention provides an electronic toy capable of displaying an emotion using an emission unit.
The electronic toy includes an emission unit, a memory system, and a controller capable of displaying an emotion of the electronic toy. The emission unit includes lamps capable of emitting light of at least three primary colors and a light mixer configured for mixing at least one color of the at least three primary colors emitted by the lamps into a displayed light corresponding to an emotion of the electronic toy. The memory system is configured for storing a color-emotion table, wherein the color-emotion table is configured for recording a relationship between the emotion of the electronic toy and the primary colors of light emitted by the emission unit. The controller, electrically connected with the emission unit, is configured for turning on or turning off the lamps according to the relationship between the emotion and the primary colors of light emitted by the emission unit.
A method of displaying an emotion for an electronic toy by a plurality of lamps includes the following steps: determining an emotion of the electronic toy; accessing a color-emotion table to obtain at least one emission time length according to the emotion; turning on or turning off at least one lamp according to the at least one emission time length; emitting different colored light with different intensities according to the at least one emission time length; and mixing the different colored light to generate a resultant color light to display the emotion of the electronic toy.
The ambient sensor unit 30 is configured for apperceiving external information from a surrounding environment of the electronic toy. Based on the external information received by the ambient sensor unit 30, the electronic toy may display one or more emotions as will be further explained herein. In one embodiment, the ambient sensor unit 30 includes, but is not limited to, an image sensor, a sound sensor, and a touch sensor, for example, for detecting brightness, sound, and pressure, respectively. The ambient sensor unit 30 may further or alternatively include other sensory elements. In one example, in order to imitate a live pet, at least one sensor from the ambient sensor 30 may be appropriately placed in predetermined positions in or around the electronic toy 1. For example, image sensors can be positioned inside an eye of the electronic toy 1, sound sensors can be positioned in an ear of the electronic toy 1, and touch sensors can be positioned around the neck and the stomach of the electronic toy 1.
The internal sensor unit 70 is configured for apperceiving internal information about the electronic toy 1. Based on the internal information from the electronic toy 1, the internal sensor unit 70 may correspond with the MCU 10 and/or other components of the electronic toy 1 in order to control and/or operate the electronic toy 1. In one embodiment, the internal sensor unit 70 includes, but is not limited to, a battery sensor, a heat sensor, and a time senor, for example, for detecting a battery power, a body temperature, or a system time, respectively, of the electronic toy 1. In one embodiment, the internal sensor unit 70 may be positioned inside the electronic toy 1.
The output unit 50 is configured for moving the electronic toy 1 and/or outputting audible sound to an environment external to the electronic toy 1. In one embodiment, the output unit 50 includes at least one speaker, such as a speaker 51 for outputting audible sound, and a plurality of motors, such as a motor 52 for driving the electronic toy 1 to move or to perform actions. In one embodiment, the speaker 51 can be positioned in the mouth of the electronic toy 1.
The MCU 10 is configured for obtaining ambient condition information based on the ambient sensor unit 30, and is further configured to obtain body characteristic information based on the internal sensor unit 70. Because the MCU 10 is a well-known technology on how the electronic toy 1 determines an action according to the characteristics detected by the ambient sensor unit 30 and/or the internal sensor unit 70, embodiments of the present disclosure omit detailed analysis of how the electronic toy 1 performs these actions. Rather, embodiments of the present disclosure detail how the electronic toy 1 emits different colored lights under the control of and according to the MCU 10 and the emission unit 60.
As shown in
The memory 20 is typically a memory system that is configured to record a relationship between an emotion and at least one colored light emitted from the emission unit 60. Depending on the embodiment, the memory 20 may include flash-based memory or any other static or dynamic memory system.
In one embodiment, the memory 20 includes a color-emotion table 21 as shown in
In another example, the MCU 10 may access the color emotion table 21 in order to display an emotion by the electronic toy 1. The accessing may include obtaining an emission time length of at least one LED corresponding to the emotion and then transmitting the emission time length to the controller 40. The controller 40 may turn on one or more lamps for a duration of time according to the emission time length. The emission unit 60 provides the resulting color based on the turned on lamps.
It may be appreciated that three primary colors can generate thousands of colors on the condition that the three primary colors are proportionally mixed. In one embodiment, the three primary colors may be red, green, and blue (RGB), while in another embodiment, the colors may be cyan, magenta, yellow, and black (CMYK).
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments of the invention.
