Evaluation Research Based on VR, EEG and ERP

Brief Introduction of the Experiments This project aims to evaluate people's user experience in recreational center in VR environment.

Experience of people in recreational center can be divided into two main categories: 1. long-term experience; 2. short-term decision-making. Therefore, the author designs and conducts two experiments to depict these two experience: one is watching

Stimuli of Short-term Decision-making in Sports 360 videos in Cave VR environment to collect EEG and eyetracking recreations and the other is taking decision-making tests after watching to collect behavior features, ERPs and eyetracking reactions. Below are diagram of the experiemental flow and introduction of the paradigm used to test the performance of decision-making in sports.

Currently, most research uses third-person camera to collect the stimuli of decision making in sports. In order to present a first-person perspective of situations on the court, the author adopts both third view camera and first-person observer. Below is the recording status of the observer.

Basketball stimuli are collected from BT, XT1 and ZT, while badminton stimuli are collected in XT1 and ZT only. (Due to venue regulations) Observer Status

Behavior Result Analysis

Correlation and Adjustment Factor

This research bases on behavior results to explain the performance of ERP, because behaviors are large-scale performance.

Behavior data is based on the average performance of participants.

In terms of basketball, accuracy shows significant difference

between venues: ZT is equivalent to BT and is better than XT. Reaction time shows no significant differences.

In terms of badminton, there no significant difference between venues.

BADMINTON

For basketball, there is a weak negative correlation between the latency of the frontal P100 component and visual search efficienc).

Renovation of West Gymnasium (XT), Tsinghua Univ.

West Gymnasium of Tsinghua University is the earliest gymnasium in Tsinghua University, and probably in all Chinese universities.

Front main hall was designed by Henry Murphy from 1916-1919, and back main hall was designed from 1931-1932. The middle hall of the gymnasium was the earliest indoor swimming pool in China where chairman Mao once came to swim.

Enhancement of Spatial Experience The renovation mainly concerns front and back main hall. The strategy is derived from the evaluation results, and falls into three categories: 1. Enhancement of spatial experience; 2. Enhancement of performance efficiency; 3. Accessible design.

The strategies for improving spatial experience in the cognitive load comfort evaluation were explained, focusing on four main aspects: 1.Enhancing the attractiveness of spatial node: mainly targeting the current main entrance, front plaza, foyer space, and the corridor between the two gymnasiums, to enhance the aesthetic 1F Plan 1:600

2. Increasing the spatial permeability of the main venue: partially opening the interfaces between the front, middle, and rear areas of the venue, allowing for active interaction between these spaces and the surrounding landscape resources.

Accessible Design

The current issue in the front hall is that the excessive amount of spatial visual information affects sports decision-making. It is recommended to unify the forms and color elements of different interfaces.

Reorganize the types and forms of the visual guidance system according to functional use, and design a more effective spatial

visual guidance system. Additionally, introduce furniture tailored to behavioral characteristics.

Participatory Design Based on AI, EEG and PAD

Background: AI-assisted Decision Making in Design

Theory: Perception and Cognition of Space

The traditional design process shows notable discrepancies and risks in terms of decisions and iteration frequency; along with client and user satisfaction. Introduction of AI into this process can enable reduced time in conceptualization, and a big potential for more scientific and user-engaged decision-making, enabling multiple iterations. Throughout the process, AI can also be trained on the feedback and decision patterns of clients and users, further optimizing the design process.

Human- environment interaction relies on two processes: Perception and cognition.

Cognition is mostly vision dominated, occuring in a wider range of surroundings.

Perception relies on multiple sensory systems exploring environments, including taste, touch, hearing, etc. This process often occurs in the closer vicinity of the person. For deep learning, human spatial perception response can serve as a dataset.

How Enivronment Relate to People through Perception and Cognition

Framework: Human Emotion Dataset Using the text generator I designed, a series of spatial scenes can be generated using the generative TEXT2IMAGE diffusion model. The outcome images are then rated by participants providing emotional assessments. A CNN model or other relevant models could be developed to train the AI to learn the correlation between the emotion data set and the input prompt. Due to the time constraint, I have used Stable Diffusion to generate the dataset for the experiment instead of training a CNN model.

With this protocol, it is possible to establish a direct connection between the written prompt and emotional outcome. In other words, AI can predict the emotional feedback of a scene based on its description.

Participatory Design Based on AI, EEG and PAD

Text Generator: Prompt Structure for Architecture Based on natural language, spatial information can be grouped into three categories: "T for Tectonics, M for Materiality, and A for Ambiance." T encompasses basic scale, shapes, and details construction within a space; M focuses on the attributes of materials in different areas; A includes non-architectural elements like time, light, and plants, etc. Each prompt must begin with this

overarching structure for consistency. After establishing the primary structure, content is further divided into secondary elements, such as Tn, Mn, and An in the diagram. The provided diagram illustrates a widely applicable prompt structure prototype, and by assigning weights to different elements, a dataset of visual stimuli with consistent difference can be efficiently generated.

ITERATION 01 Num = 2x8 Selected = 5 Drop Rate = 68.75%

ITERATION 02 Num = 2x8 Selected = 8 Drop Rate = 50%

ITERATION 03 Num = 2x8 Selected = 3 Drop Rate = 81.25%

FINAL SELECTION Num = 2x8x3 Selected = 2x8 Drop Rate = 66.67%

Paticipatory Design Based on AI， EEG and PAD

Process The experiment is divided into four steps: pre-experiment, selection, PAD assessment, and self-report.

The "PAD Scale" typically refers to a scale that measures three dimensions in emotional responses: Pleasure (P), Arousal (A), and Dominance (D).

Based on the established definitions of the PAD values for the eight basic emotions, I conducted cluster analysis and correlation analysis to obtain conclusions.

Conclusion In the positive group, there is a moderate negative correlation between Materiality and Dominance. In other words, the stronger the materiality is, the less control people feel over the space.

In the negative emotional space, the stronger the negative spatial Atmosphere is, the more negative the emotions become.

Taking a comprehensive view, Tectonics, Materiality, and Atmosphere are moderately negatively correlated with Valence and Dominance. Tectonics is strongly positively correlated with Valence.

Independence Test P (Pleasure, Arousal) = 0.00026 P (Pleasure, Dominance) = 0.000096 P (Arousal, Dominance) = 0.000000 (P<0.05 means independence)

Confirmatory Design: Museum of Emotions

Attention Allocation: EEG and Eye Movement

Using conclusions from AI experiments, the museum project designed two halls with the intention of evoking contrasting emotions. Remaining spaces serve the purpose of connecting between these emotions. The concept of the spatial sequence extends from the land into deep underwater, returning to the sea level at the end. This sequence of spaces allows individuals to follow an emotional journey starting from neutral state to positive emotions, then to slightly subdued negative emotions, returning to ultimately a calm state.

Analysis focused on anterior frontal cortex reactions that are related to positive and negative emotional responses.

Results show enhanced positive responses in samples from BIN 01, 02, and 03, while BIN 04 and 05 exhibits calming effects.

In eye-tracking analysis, individuals are observed to first focus on prominent figures in the space, followed by areas with special shapes. In places without specific design features, scan patterns tend to be more scattered.

Laboratory Setup

Record

The laboratory is located at the Sports Rehabilitation Center of Tsinghua University. The experiment setup used a combination of polymer jump boxes in different heights to simulate different interfaces.

Experiment equipment includes planting tools (succulent plants, plant pots, shovels, spray bottles, beakers, planting soil), wearable devices (EEG equipment, Xsens devices), recording tools (Canon camera), and preparation tools (alcohol swabs, cushions).

The experiment involved a total of 9 male participants, aged between 21 and 23, with no vigorous physical activity within the 24 hours before the experiment. Each participant was required to complete the described experimental tasks on 6 interfaces, and I recorded their actions while collecting real-time data throughout the process.

Process Participants are required to complete four planting tasks in 60s. After completing the tasks, participants are required to fill out a fatigue assessment scale, rest for 1 minute, and proceed to the next. There are 7 formal experiments in total.

Futurniture Design Based on Ergonomics and EMG

Conclusion

Ergnomic Design

By processing electromyographic (EMG) data using Relative Integrated EMG (Relative IMEG) and Relative Root Mean Square (Relative RMS), features of different interfaces are compared.

The data indicate that 45-30 and 45-45 IFs effectively increase energy expenditure during the experience of farming activities. Additionally, most subjects exhibit a characteristic of greater muscle activation on the left side.

According to the experimental findings, designs were developed around 30-30, 45-30, 45-45, 60-45, and the standard interface 75-30, which can increase muscle energy expenditure. The baseline was set at the 75-30 interface, a height that is generally comfortable for most individuals. The design takes into account considerations such as adjustable lighting and storage function. An assistive device has been set up on the left side of the human body to address the issue of easier fatigue in the left-side muscles.

Detailed Section

Planting Space on 1F

The detailed design carefully considers both the physical requirements for optimal crop growth and the interactive planting experience for visitors. The overall structure is constructed using 50x50x4.8mm angle steel. The selected interfaces for visitor planting include configurations of 75-30, 60-45, 45-45, and 30-30. Interfaces positioned above 200cm are designated for staff maintenance, with lighting seamlessly integrated into the load-bearing panels.

The planting system utilizes a drip irrigation setup, and water pumps in containers below 30cm supply nutrient solutions for cultivation. The floor ventilation system addresses the necessary temperature and humidity requirements for ideal crop growth. Adjustable lights cater to various interface heights.

At 75cm, an accessible facility aids standing up, specifically designed for the right-handed people. At 160cm, there is an LED screen attached to the toolbox, providing real-time information on crop growth, environmental CO2 concentration, etc.

The individual in the image is scanning the code to monitor the crop's growth progress. The hydroponic tanks in the foreground serve as interactive elements for individuals to engage with.

Personality

Shostakovich was a Soviet musician. He was considered one of the most influencial composers fo the 20th century. His music was full of emotional expression and deep thoughts of his time and his experience. His famous work including Symphony No. 5, Symphony No. 7, Jazz Suite No. 2,etc.

- Shostakovich wants to use music to express his real thoughts and feelings.

- Shostakovich wants to use music to commorate his "vanished" loved ones.

-Shostakovich wants to use music to record the the darkness of Soviet Politics under the rule of Stalin.

- Shostakovich felt hard to sleep at night because he was afraid of being arrested and executed unexpectedly.

- Shostakovich felt reluctant to express himself openly in the public.

-Introverted -Reserved and conventional -Cautious and thoughtful -Emotional and sensitive

Relationship With Joseph Stalin Shostakovich kept a subtle and complex relationship with Joseph Stalin. On one hand, Stalin expressed open disagreements with some of Shostakovich's work. On the other hand, Stalin didn't execute Shostakovich like what he had done to other artists.Instead, he appreacited shostakoviche's talents very much, especially for his Symphony No.7 . Therefore the music of Shostakovich is always full of contradictory and complicated expressions.

DMITRI SHOSTAKOVICH 1906.09--1975.08 Composer, Painist, Teacher

Study on the Score of Symphony No.7 Shostakovich's Symphony No. 7 consists of four movements, titled "War," "Memories," "My Native Field," and "Victory." The first movement is renowned for its nearly 26-minute duration.

Deviating from the traditional symphonic structure of "Exposition, Development, and Recapitulation," the first movement innovatively inserts an 11-section episode depicting the invasion of the troops.

The symphony delineates four distinct images: the people, soldiers, troops, and the composer. A visualization method, invented by Iannis Xenakis, has been employed to analyze the visual presentation of these themes. This approach defines the character of each theme from the perspectives of rhythm, melodic trajectory, and the primary instruments used in the performance.

Theme 02 Soldiers Consisting mainly of archi, the melodic character of the higher voices is a definite continuation of the upward or downward movement, expressing a color of perseverance and optimism.

Theme 03 Troops The long lines of brass, accompanied by strong rhythmic and monotonous rhythms, express the color of horror.

Theme 04 The Composer Consisting mainly of woodwind harmonies, the curved and blurred downbeat tune expresses a mysterious and hesitant color.

Problem : Color on Mars

Method : Color Therapy

Concept : Home as a Digital Life

The mineral composition on Mars, characterized by the presence of iron oxide (hematite), gives the planet a reddish-brown color. Red is believed to trigger intense emotional reactions in humans, such as excitement and tension. These emotions often manifest with increased left-hemisphere EEG activity.

Prolonged exposure to such an environment may result in increased heart rate, elevated blood pressure, and diminished sleep quality. Consequently, the psychological challenges faced by individuals on Mars could indeed become a critical factor for the survival of the human species.

Color therapy is a holistic healing approach that utilizes colors to enhance health and well-being. The practice of color therapy dates back to ancient India, as depicted in the illustration below.

The main idea of color therapy is that different colors are linked to specific energies and vibrations. Then Exposure to these colors is thought to exert diverse effects on the mind and body.

We believe that the habitats on Mars should assume the role of companions, transforming residents from a state of typically limited interaction to active engagement, combined with the color therapy theory mentioned. Unlike traditional AI assistants, we posit that a Digital Life could be a form of a biological nervous system, possessing its own thoughts and emotions.

User Journey Map Based on the synchronization of emotions between users and the digital life, we propose 6 primar y scenarios. The Digital Life is composed of an inflatable membrane structure (as shown in the diagram below), which interacts with individuals through varying degrees of hardness. For example, when both are in a happy state, the inflation pressure of the membrane increases, allowing for experiences akin to playing ball games.

Conversely, when the user is down, the pressure decreases, fostering a softer interaction between them.

Pipeline for Form Generation

II. Kangeroo Physics Simulation

Our concept is that homes on Mars should have the potential for customization. Therefore, we employed cellular automaton to define framework, allowing individuals to choose. Then we usd

kangaroo physics simulation to integrate the form of the inflatable membrane. Finally, we employed Culebras particle dynamics to generate the pipelines for the life support system.

We utilized the inflation simulation in Kangaroo to achieve the desired spatial effects. To reduce computational complexity, we divided the inflation and collision into three steps. The 3.6m

frames were first computed to define the framework for the next step. The 1.2m units were then further computed on this basis, and finally, inflation was carried out based on the defined positions.

To achieve a more natural and organic pipeline form, we used Culebra for simulation. We initially defined the starting position, quantity, and movement speed of the particles.

The entire process can be divided into three stages: the first stage involves particles coming into contact with the outer shell; in the second stage particles move onto the outer shell; and in the third stage, particle trajectories depart from the starting position, covering the entire outer shell.

Detailed Section The detailed design is based on existing lunar bases and conceptual proposals for Mars habitats. The inner shell membrane retains the possibility of continued inflation, inspired by the design of spacecraft portholes. The outer shell refers to the construction methods of existing lunar bases, using inflatable membranes to form the main structure, filled with Martian soil, reinforcing agents and coated with protective substances. The energy platform draws on the MARCO POLO system proposed by the European Space Agency. The support structure is modeled after NASA's Athlete structure, generated through 500 iterations of graphical statics.

Generation of the Community Form

Systems of the Community

In the crater located in Mawrth Vallis, there are 40 Digital Life households. They have the ability to move to different locations based on different tasks, forming a nomadic society.

To achieve urban planning based on this mobile concept, we employed the Particle Swarm Optimization (PSO) algorithm. Four tasks were defined: charging, working, wandering, and resting.

Different force inputs were then defined for trajectory simulation, resulting in the formation of a unique urban structure.

We defined several types of community zones: residential, industrial, green, energy, and undeveloped areas. The relationships between these zones are determined by the results of the previous simulations.At the same time, cluster analysis of

Problem: What Happens to Human Bodies in Space?

Method: Motion Capture

Due to the microgravity conditions in space, the human body encounters formidable challenges across various physiological systems. The nervous system is particularly susceptible, experiencing disruptions in brain regulation due to the absence of distinct day and night cycles. Subsequently, the fluid and circulatory systems are also affected...(as elaborated below). After adapting for about one and a half months, the functionality of the human body significantly diminishes compared to terrestrial conditions.

Therefore, ensuring the physical and mental well-being of astronauts is a critical challenge.

I conducted motion capture research on the freestyle swimming movements of members from the Tsinghua University swimming team. In this study, the athletes wore Xsens motion capture devices on land to simulate freestyle swimming for a duration of 45 seconds. In the subsequent data processing phase, I selected the mid-section of the motion sequences for frame-by-frame analysis. Each cycle of the freestyle swimming motion lasted approximately 1 second.

Nervous System Crowding of the sulci can be seen at the vertex. The gyrus (asterisk) is the precentral gyrus (primary motor cortex). *J.Effects of Spaceflight on Astronaut Brain Structure as Indicated on MRI.

Muscular System In space, the muscular system undergoes atrophy and decreased muscle mass. Weightbearing muscles, especially in the lower body, are particularly affected.

Circulatory System The heart has to work less against gravity in microgravity, leading to a decrease in its mass and changes in its shape, resulting in changes of blood volume and blood pressure.

Skeleton System In space, the microgravity environment leads to bone density loss, increased bone resorption, and changes in bone architecture.

Posture Analysis Comparing motions obtained directly in the global coordinate system with those analyzed relative to the shoulders, swimming postures in the global coordinate system exhibit an X-shaped symmetry, with hand movements notably having a larger range than leg movements. The trajectory of hand movements in the sagittal plane can be roughly equivalent to an ellipse.

In the analysis relative to shoulders, hand movements are primarily in the lower part, while leg movements sometimes occur above. Shoulder-coordinate effectively reduces the spatial volume occupied by hand movements and increases the range of leg movements. Therefore, subsequent designs will follow the shoulder coordinate system.

Scenarios During the space travel between Earth and Mars, land swimmer proves to be a versatile tool in supporting astronauts' physical well-being across different scenarios.

Its utility extends beyond the confines of space, starting with its application on Earth. Acting as a home or gym fitness apparatus, it not only serves the practical purpose of exercise but also offers an engaging and enjoyable workout experience for users.

When utilized within spacecraft or space stations, the equipment's compact design doesn't compromise its effectiveness. It efficiently integrates muscle resistance training and aerobic exercises, presenting a holistic health solution tailored for astronauts.

Looking ahead to the Martian landscape, where gravity is only a third of Earth's, this land-based swimming equipment could become a focal point for training in homes or community centers. This equipment can play a pivotal role in addressing the diverse health needs of individuals living or working on the Red Planet.
