【正文】 ell in the development of toys for the old persons, and most toy panies have produced toys for seniors, and continued to introduce new products. 2． The meaning of the development of toys for the seniors Retiring from work, the senior people get more time than before. Besides watching TV at home, they have no many alternative entertainments. Some old people have been for a long period in loneliness. Over time, they are prone to depression, anxiety disorder and Alzheimer’s, seriously affecting their physical and mental health and bee burden to children and society. Li guangqing in department of rehabilitation of Beijing Xuanwu Hospital once said: “with age increasing, the function of the body of the seniors gradually degraded, and their reaction will be clumsier. At the same time, retirement from work, the opportunity for the old to use their brain reduces, which further brings the decline of attention and cognitive ability. Except to maintain good habits and moderate exercise, to slow down brain aging, putting hands and brain in work at the same time is the most effective way, which is exactly the function of toys. for people with Alzheimer’s, playing with toys, to some extent, would alleviate the condition. Therefore, toys can develop people’s thinking ability, and improve our intelligence. If the seniors play with toys constantly, the aging of the brain and the Alzheimer’s would be effectively prevented. Medical experts found that to maintain old people’s intelligence, we must first fully protect the brain. In addition to proper nutrition and adequate sleep, the seniors should make most of the brain. Just as Chinese saying tells that” water does not rot, and the door hinge is never wormeaten “, the more one use his brain, the more sensitive it bees. Playing with toys is exactly a good way to use the brain. With toys, the old people not only receive more information, at the same time bee more optimistic than before, thereby enhancing their immune system function. 3． The needsanalysis of toys for the old What is a needs analysis? This approach is to focus on the users’ needs. Users’ needs are sources of many new products. What is the demanddesign? it is the most frontend process for new product in its life cycle, and decides the success or failure of the new products. Needsdesign starts from the businesses and designers’ judgment of the market or the needs of users, and ends at planning proposals or technical specifications on description of the product development. Understand the market or user demand is a highlevel investment for the success of the product. The development and design of toys for old persons should start from the needs of the seniors. Only a real understanding of the old consumers and their psychological and physiological needs can bring toys that give practical cares for the seniors physically and spiritually. Toys for the old should bring human care. Toy design process should be integrated into this concept. The aim of the toy design for the old is enhanced, with seniorscentered design principles, and with the help of analysis on the seniors’ physiological psychological characteristics, cultural level and lifestyle. The toy design principle that shows humane care for the seniors is reflected at the same time. (1)Safety first To varying degrees, the judgment, cognitive ability and ability to respond of the old people weaken, thus in the process of using the product, they inevitably make mistakes. In case a threat to physical and mental health occurs, they usually are unable to escape the danger. Therefore, toys for the seniors should be faulttolerant. So that, the old people even make a mistake, there will be no danger. Here the reduction of operation process and the set of message for safe operation is an effective way to ensure the safety of the seniors with toys. (2)Moderate difficult The design of toys for the old should be of moderate difficulty, and the purpose is to arouse their interest in playing. If too simple, it would not enhance the interest of the seniors and thus would not achieve the aim of exercising the brain。s Social Intelligence, Anhui People39。s availability, usability and user39。 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。 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。 meanwhile, the action of tap is not only funny, but also effective to train children39。s learning English, so we focus on developing an interactive English learning toy to help the children rememb
