Design Practice Of Child Lost Prevention App Based On Context Awareness

With the progress of society and the improvement of people’s living standards,tourism has become an important form of people’s leisure activities.The scenic spot has also become the main place for people to carry out parent-child activities.One of the hidden dangers and urgent problems.Based on the context perception theory,the author uses the situation analysis method and service design thinking to design the functional design and interface visual design of the Chongqing Zoo Child Lost Prevention App,and designs its peripheral derivatives.This article discusses from the following aspects:First,from the perspective of services,the author analyzed the existing representative child loss prevention system and summarized the following problems:Ignoring the relevant education before the child loss,lacking the linkage tracing in the child loss,and lacking the psychology after the child loss Counselling and care services.Secondly,through a comparative analysis of existing child loss prevention related applications,the author finds that the current Child Lost Prevention App function is only for information release after child loss,and the front-end display and back-end tracing links are separated,which cannot meet the needs of users to see the search process on the front-end interface demand.Therefore,the author uses the situation analysis method to analyze the use situation of the anti-lost child application,innovate the anti-lost child system concept,and build an interface design model.Finally,the author designed the user behavior model for parents,tourists,and employees in the design of the Child Lost Prevention App function:"One-click report of loss-early warning process-go to claim" parents report the behavior of the loss;"Receive lost Children’s information-find suspected missing children-provide clues "tourists provide clue behavior patterns;employees who" receive child-seeking tasks-go to lost places-update the tracing process "immediate feedback behavior patterns.In terms of visual design,the author uses traditional semiotic methods to extract the main design elements.While ensuring the function,the environment and culture are also integrated into the overall visual design of the interface.Need to pay attention.Child Lost Prevention App design is a topic that requires multidisciplinary cooperation to complete.This topic only completes the work on the interaction and visual design of the Child Lost Prevention App,and the background implementation technology requires other relevant professional interventions to complete.With the continuous development of technology and the growing awareness of people’s safety,it is believed that child lost prevention mobile applications will truly open up the front and back barriers in the near future,which can quickly find lost children and promote the peaceful development of society.
