Research Service Design Based on Online Public Service Platform — APP Design for Mutual Learning Through Sign Language Short Video

Deaf people is a special group whose biggest social barrier is that it is difficult for them to communicate with hearing people. Puji Public Service Net Platform has been devoted into the popularization of the sign language culture, with the convergence of all kinds of stakeholders such as volunteers, public service organizations, deaf groups and government administration department. Cooperated with Puji Public Service Net Platform, our designing team has established an ideal multiple-contact service mode through the factual and desktop research, the service designing tools such as personas and case studies etc. The designing of “The Taste of Sign Language” APP is devoted into promoting equal communication through video communication of learning sign language between the hearing people and the deaf. Through recording the life little by little, sharing thoughts and online social scenes of the information, the short video application motivates the ‘performance’ desire of the users, builds the empathy, gradually improves the user stickiness and helps the users to form a habit. The development and application of the service designing has provided new trainof thought and solutions for public welfare undertakings.
