In daily life, human beings interact with the real world in an intrinsic multi-sensory way, obtaining information and interacting through the use of various senses that allow them to perceive the environment. At a computational level there are virtual environments with which people are allowed to interact with certain degrees of freedom in which the user experience is sought to be as friendly as possible and allowing the user to feel comfortable and involved with the virtual environment. This work presents a collection of information on related work of multi-sensory human-computer interaction, in which users interact with a virtual environment through the use of various senses. The user experience, can be defined as dealing with how the user feels and understands the virtual environment when using it. Collaborative decision-making, which is the process in which two or more people meet to solve a concern cooperatively seeking to achieve a consensus after analyzing the situation and the different scenarios that it has. A Decision-Making Centers allows decision-makers to visualize and carry out large-scale analysis in person, interacting and collaborating with each other to reach a consensus that benefits all parties involved, immersive virtual reality, which are virtual environments in which the user has a greater sense of presence within the environment, and remote sessions in real-time, which are the way to communicate at a distance in real-time. In addition, this work addresses the need to have an immersive multi-sensory virtual environment in which people can come together to make collaborative decisions remotely in real-time, allowing decision-makers to feel as if they were in a traditional Decision-Making Center in person, but with the advantages offered by multi-sensory, immersive, remote, collaborative virtual reality in real-time. Therefore, a software architecture is proposed that allows the creation of Multi-sensory Virtual Decision-Making Centers (MVDC) with the capabilities of being collaborative, immersive, and remote in real-time. Together with this architecture, a multi-sensory environment was created which is the first MVDC that exists, this MVDC has the characteristics and capabilities to carry out remote collaborative decision-making sessions in real-time in addition to adding an immersive multi-sensory experience while using it, ensuring that the sense of presence among decision-makers is not lost and allowing the remote decision-making session to be as similar to a face-to-face session. Along with this, an experiment and analysis of the results are carried out to validate the improvement of the user experience when carrying out remote decision-making sessions in real-time with the MVDC environment. Finally, the conclusions obtained from the work carried out are presented and some ideas and recommendations are presented for future work related to what has been presented.

Information is one of the most valuable resources, and its use is critical during the decision-making process within the organization. Technological evolution has given way to the development of tools that allow organizations to have more efficient processes. The information visualization tools are a resource that facilitates the analysis of critical information and that allows decision-makers to consider the different variables and their effect when taking a resolution. However, before the rise of the visualization tools as well as their diversity arise some questions. What characteristics should these tools have to be effective and give dedicated support to the decision-making process by visualization of information? How can we ensure that an information visualization tool is competent and conforms to the needs in the decision-making process? In this work, we make a metric proposal for the evaluation of visualization tools. In our metric proposal, we consider criteria that are important for specific use in the decision-making process. The objective of our metric proposal is facilitating the selection of an information visualization tools since the selected criteria will permit the evaluation of tools to find those who fulfill the decision-making process needs. We also made an architecture proposal for the development of visualization tools, considering the criteria defined in our metric proposal. In this way, we can ensure that our architecture proposal meets the needs of the decision-making process and that its use will allow obtaining benefits as knowledge generation, ease of analysis through the simultaneous presentation, interaction, collaboration, and real prospective in a multi-screen environment with information update in real-time. This work includes the review of related work in terms of existing visualization tools and existing evaluation methods. Likewise, we did the corresponding tests and analyzes that demonstrate its validity. Finally, we conducted the conclusions, and in future work, we consider the possibility of continuing this proposal that requires a more extensive development.
