What is HAII?

HAII focuses on exploring and designing the ways in which humans and AI systems interact and work together. AI systems are computer programs capable of performing tasks that typically require human intelligence, such as processing natural language, recognizing images, making decisions, and learning from data. The goal of HAII is to develop AI systems that are intuitive, reliable, ethical, and advantageous for humans. This field encompasses various forms of AI, including narrow AI, general AI, and generative AI.

History of HAII

HAII has evolved from rule-based systems to deep learning technologies, and the future aims to foster more collaborative and human-centered AI. The history of HAII can be summarized in the following stages:

1. Origins (1950s-1960s)
   The history of HAII development can be traced back to the early stages of AI. Alan Turing proposed the Turing Test, laying the foundation for AI. Early AI systems performed specific tasks (like playing chess and translation) but were limited to simple rule-based logic and struggled with complex or uncertain situations.

1. Exploration of New Methods (1970s-1980s)
   Researchers shifted towards neural networks, fuzzy logic, and expert systems to simulate human thinking and learning processes, advancing technologies like speech recognition and computer vision. However, these systems still faced challenges related to explainability and reliability.
2. Breakthroughs in Deep Learning (1990s-2000s)
   Deep learning enabled AI to surpass human abilities in tasks like image recognition and natural language generation, leading to innovations such as conversational agents and recommendation systems.
3. Future Directions (2010s-present)
   Current AI research focuses on improving transparency, responsiveness, fairness, and explainability, aiming to create systems that adapt to user needs while addressing ethical and societal issues. This reflects a shift from purely technical tools to more interactive, human-centered systems, as seen with early virtual assistants like Siri. AI is increasingly integrated into daily life, and developers must ensure its decisions are transparent, fair, and adaptable to diverse cultural and individual contexts.

Artificial Intelligence (AI) technology is bringing numerous benefits to humanity, but currently, many AI systems are still developed with a "technology-centric" approach. Research indicates that inappropriate AI technology development has led to many incidents that harm humans. The AI Incident Database (AIID) tracks cases of ethical misuse of AI, such as pedestrian fatalities caused by autonomous vehicles and wrongful arrests resulting from facial recognition systems. Data shows that there were 123 reported AI-related incidents in 2023, a 32.3% increase from 2022. Since 2013, the number of AI incidents has grown more than twentyfold. Based on these facts, AI researchers emphasize that future AI development should place humans at the center, rather than focusing solely on algorithms and technology itself.

While HAII focuses on the ways humans interact with AI systems, Human-Centered AI (HCAI) ensures that these interactions are designed with human needs at the core. As such, the growth and trends in the HCAI market provide valuable insights into the broader evolution of HAII practices. In recent years, the development of HCAI has garnered significant attention, especially as AI technologies continue to evolve and integrate into daily life. The global HCAI market is projected to reach approximately USD 68.8 billion by 2033, up from USD 9.5 billion in 2023, reflecting a compound annual growth rate (CAGR) of 21.9% from 2024 to 2033. In 2023, Virtual Assistants and Chatbots led the By Application segment of the HCAI Market, capturing more than 31.5% of the market share. These technologies have played a crucial role in improving customer engagement and automating communication processes across various industries.

In 2023, the Healthcare sector led the By Industry Vertical segment of the HCAI Market, accounting for over 24.1% of the market share. This dominance highlights the significant impact of AI in transforming patient care, improving medical diagnostics, and enhancing operational efficiencies within the industry.

GenAI

Generative AI (GenAI) is a type of HAII. It enables interactive experiences by generating content like text, images, and music based on user input. Through natural language processing and machine learning, GenAI allows for personalized interactions, such as chatbots that respond to queries or tools that create content like articles or artwork. By offering tailored, creative, and adaptive responses, GenAI enhances HAII, potentially boosting business efficiency and profitability. The McKinsey survey reveals that many industries are increasingly allocating a larger portion of their digital budgets to generative AI. This trend is expected to continue, with 67% of respondents anticipating that their organizations will increase AI investments over the next three years. As a result of these investments, organizations are already seeing tangible benefits, including cost reductions and revenue growth in the business units that have adopted generative AI technology.

Healthcare

As we previously mentioned, the healthcare sector holds the largest share in the global HCAI market within industry verticals. In Mckinsey's Q1 2024 survey, over 70% of healthcare organizations reported that they are actively pursuing or have already implemented gen AI technologies. This growing adoption underscores the significant potential of gen AI to enhance patient experiences and optimize healthcare operations. Clinician productivity is identified as a key area where gen AI can have a substantial impact, with 60% of users already seeing or expecting a positive return on investment (ROI). Furthermore, there is increasing focus on how human-AI collaboration can improve patient engagement, administrative efficiency, and overall care delivery, further highlighting gen AI's potential to improve clinical efficiency and the entire healthcare industry.

Furthermore, a scientific report explores the collaboration between humans and artificial intelligence (AI) in medical decision-making. AI provides powerful data processing capabilities and offers intuitive cues of reliability. This allows doctors to effectively balance their own judgment with AI recommendations, resulting in more accurate diagnoses. This human-AI collaboration leverages the strengths of both parties, demonstrating the complementary benefits this partnership brings to medical decision-making, ultimately improving the quality of diagnostic outcomes.

Current Challenges：

While HAII offers numerous advantages and has made significant progress, there are also several challenges that it currently faces.

1. Large Pretrained Models

·      Challenges: Current large models require substantial computational resources and storage, with speed still being a significant issue, especially during training and inference. Running these models on resource-constrained devices, such as smartphones or wearable devices, can result in delays and inefficiencies. Additionally, applying these large models to specific domains (such as healthcare, finance, or law) and delivering personalized and accurate services is another challenge.

·      Development Direction: The future development of HAII will focus on addressing these issues by researching advanced technologies to optimize the efficiency and scalability of AI systems, particularly in resource-constrained environments, while ensuring that AI can provide accurate, domain-specific solutions.

2. Explainable AI (XAI) and Interpretability

·      Challenge: Despite the power of large models like deep neural networks in various tasks, their "black-box" nature makes their decision-making processes difficult for humans to understand and trust. In critical decision-making scenarios, especially in fields like healthcare and law, it's essential to know how AI arrives at its conclusions.

·      Development Direction: Future HAII systems will place greater emphasis on explainability and transparency. AI will need to clarify its decision-making process to help users understand the rationale behind its suggestions. In healthcare, for example, when AI provides diagnostic recommendations, being able to explain the reasoning behind these suggestions will help doctors assess their appropriateness more effectively.

Conclusion

HAII has made significant strides in improving efficiency and personalization. However, challenges such as the need for large computational resources and the "black-box" nature of AI models persist. Future developments in HAII will aim to address these issues, focusing on optimizing AI systems for resource-limited environments and ensuring transparency and trust through explainable AI.
