Description

Interactive path guide system

Technical Field

The invention relates to the technical field of path guide, in particular to an interactive path guide system.

Background

The guide, as a part of a culture or culture, not only has the functions of guiding, explaining, indicating and the like, but also is an important link of environment layout and an important component for building style and shaping the culture. Its function can be fully exerted only by fully understanding and correctly recognizing it.

The identification system mainly comprises four aspects of vision, hearing, smell and touch.

The guiding can be understood as guiding, indicating, guiding and line of sight according to the meaning of the words.

The guide system is also called as a guide system, and learners think that the concept of the guide system is more accurate in the identification industry. While other experts consider these two concepts to be identical, in fact, the two concepts are not very different in the early stages. However, as the signage industry has matured, the "guide" and "guide" have in fact gradually separated into two concepts. The 'guide system' is based on the function of indicating guide, focuses more on the improvement of visual image, and even some theories incorporate the 'guide system' into enterprise VI. The 'guidance system' focuses more on the implementation of the guidance and visual function. Whether the 'guide system' or the 'guide system' is a medium for environment information and human communication. Particularly, in a complex urban environment, the function of the 'guide system' is more prominent.

The guidance system is an overall collection of individual identification tags, each carrying environmental information, and is therefore said to be an information interface system that incorporates the relationship between the environment and a person. Only in the course of vision and cognition is the observer who is the individual identification tag the object of recognition, so that it is embodied as an individual shape of the identification tag. But for the overall environment, the navigation system is a well-established system that includes a plurality of identification signage singlets.

With the continuous improvement of the requirements of people on living environment, the application range of the guide system is more and more extensive, the guide system is widely applied to public spaces such as modern commercial places, tourist attractions, public facilities, urban traffic, real estate communities, industrial parks and the like, and the guide system is not an isolated single design or a simple label or identifier any more, but a systematic design integrating brand images, building landscapes, traffic nodes, information functions and even media interfaces. For example, in tourist attraction ratings, a sophisticated navigation system has become one of its rating criteria.

However, the conventional route guidance system mainly uses static indicators, cannot be interacted with each other, is not very recreational, and generally cannot attract users to use the route guidance system first. In addition, the traditional path guide system is based on the non-interchangeability in the front, so the information display is single-layer, and a user can only find information on the indicator and determine a path from the current position to a destination by himself or herself when using the system, which wastes time and labor, and causes great visual load and cognitive load for the user.
