RETRACTED ARTICLE: App interaction design in the pop music singing teaching system based on differential evolution algorithm

The dynamic spectrum management of cognitive technology can greatly increase the utilization of network spectrum, but while bringing convenience to our daily lives, this new technology will also greatly increase the consumption of nodes. At present, the short video industry is growing rapidly with the development of smart phones. Among them, the emergence of online popular music singing teaching platforms (mainly software for shooting short videos with music as the background) has brought significant changes to people’s lifestyles. We can learn from the three-stage theory of flow experience to design and explore the method of plan implementation, and propose a targeted interaction design strategy for each flow characteristic, so that the overall design strategy becomes more practical and practical. In the design of this paper, the principle of cognitive wireless sensor network is applied in the technical aspect and the principle of interactive design is applied in the product design. When a user reaches a state of flow while using the online popular music singing teaching platform, it can be evaluated that the user experience of the app is the best. The research on the interaction design of the online pop music singing teaching platform under the flow experience is intended to propose an interactive design strategy that can guide the online pop music singing teaching platform to better create a flow experience for users.
