The realistic educationalgame scenario created by interactive educational toys for children not only brings emotional pleasure experience to children so that learning is no longer boring for them with a purpose of mobilizing the enthusiasm of study and developing creative thinking, but also enhances children39。s social munication ability to help children establish good social character favorable for their life. 3. DEVELOPMENT OF INTERACTIVE EDUCATIONAL TOY— FUNNY TAP Parents are headached on children39。s learning English, so we focus on developing an interactive English learning toy to help the children remembering words in game scenario and stimulate their interests in learning English, and training children39。s hand operation and brain coordination. The development practice procedure of interactive toy for childrenfunny tap is shown in Figure 2 as following: Fig. 2. The development practice procedure of funny tap . The development process of interactive concept of interactive educational toyfunny tap It is the development process of funny tap interactive concept. After investigating the object group of children and parents about their needs of English learning machine, we summarized six key indicators such as security, fun and incentive. Here we mainly describe three models of interactions shaded in Figure 3. To meet the requirement of fun, the author designed a narrative interactive process, as is shown in Figure 3: Fig. 3. The narrative interactive process of funny tap The word learning process is conceived as a game of whackamole, imagining there are N mole holes, and there are M letters in a word (. M moles with a letter). If you tap down M jumping moles in accordance with the order, you will get the cheers, if the tap is not correct, it will continue to call e on。 meanwhile, the action of tap is not only funny, but also effective to train children39。s hands and brain coordination. Voice interaction was prepared by the microcontroller program to control the voice modules. There are two features regarding the funny pat: one is word pronunciation。 the other is the design of the applause and cheering voices for reward and punishment, which help to reach the goal of incentive. In the first stage, video interaction was prepared by displaying the letters on buttons through LED dot matrix character display modules mainly controlled by microcontroller。 in the second stage, we provided toy with 3D projector for projecting the whole process in the air to construct a 3D emotional scenario, and the action of tap is to tap the projections in the air. . Principle diagram of interactive educational toy for childrenfunny tap The operation principle of funny tap is shown in Figure 4: Fig. 4. The operation principle of funny tap The system consists of six ponents, such as voice module, LED indicator, action back module, MCU, power module and LED dot matrix character display module. Among these, the three formers are connected with MCU through 8bit data bus。 LED dot matrix character display module is connected with the microcontroller through the 12C bus. Voice module stores English word pronunciation documents needed in the game, and MCU pronounces the word by controlling the voice module via the bus. LED dot matrix character display module consists of driver chips and the 8*8 LED matrix. MCU bus control LED dot matrix character display module via I2C to show the corresponding English letters. Action back module tests and captures the player39。s actions during the game for the MCU to judge whether the player conducts normal actions to control the game process. . Appearance design process of interactive educational toyfunny tap The following Figure 5 is a design process from sketch, modelling, modelmaking to the final product and the drawing of the product structure explosion. Fig. 5. Appearance design process of funny tap . Interaction test Sample of N (N is an odd number) preschool children was randomly selected to test the product39。s availability, usability and user39。s willingness of using it. Mainly onsite testing observation and questionnaire survey, and then we improve the product according to the test results. Testing times are equal to or more than I so as to find the products with highest interaction. In the product final trial, most of parents fed back that this toy bined fun and knowledge well and the whole learning process was very smooth and the children were very happy when learning. 4. SUMMARY AND PROSPECT China is a large country of toy manufacturing, but it still remains in the stage of imitating foreign design, especially in educational toy design. The research and practice of interactive educational toys in this study is expected to give some thought and inspiration to toy designers so as to further promote the development of Chinese toy industry.
