Disney studies playmate robots for perfect verbal communication with children

March 7 news, according to Techcrunch reported that Disney's research department Disney Research is studying the influence of speech mode and style, looking for ways to improve the quality of interaction between humans and robots. In the research, Disney's humanoid robot can imitate the play mode and style of playmates and try to create a perfect communication experience. In general, computer-generated speech and interaction patterns are very rigid and people may not want to communicate with them. And between people, such as children playing with each other, they conduct more verbal communication and are often more successful. In the study, the researchers teamed up with children and robots to allow them to play platform games. One player told the character to go and another player told the character to jump. They developed this system by listening to the child's voice and extracting some basic features: loudness, byte length, and frequency. For example, some children may respond quickly, but when they jump, they may be prolonged. The other children responded with a bit of hesitation, but they were faster and louder when they said they were going. When the child's speaking style is confirmed, the robot can choose verbal responses from slightly different sound files, and the tone and speed of speech are also slightly changed. In one case, it chooses the style of speech that is closest to the child. In other cases, it basically can choose any style other than children. Each child plays synchronous and asynchronous multiplayer games with the robot. The results showed that children with a similar choice of speaking style robots have higher participation and scores. And when they play an out-of-synch version, the child scores lower and is less active. In further analysis, it was found that this difference only affects older children. This means that people’s willingness to cooperate is through socially learned skills.

Concave Lens

Reasonable selection of materials (texture, bubbles, impurities, uniformity); When grinding, it is considered that there is no scattering (scratch, dent, gloss) when it is used for interference light.

It is possible to provide an anti reflection multilayer lens without coating and coated with a visible band domain.

The focal length of a single lens is the distance from the main point to the focus. The design wavelength of the lens is 546.1 nm (E-line of green mercury line). Since the focal length changes with the wavelength, when it is used for other wavelengths, the focal length also changes.
