In this article, we’ll dive into the history of AI, tracing its origins and major milestones. Continue reading to the end to discover how AI has evolved through history.

The Early Imaginings and Theoretical Foundations

Long before the term “artificial intelligence” was coined, humans dreamed of creating intelligent machines. Ancient myths and stories from various cultures feature mechanical beings endowed with intelligence, showcasing early human fascination with mimicking life through machinery. For instance, in Greek mythology, Hephaestus, the god of craftsmanship, created mechanical servants.

Fast forward to the 17th and 18th centuries during the Enlightenment, when philosophers and mathematicians like René Descartes and Gottfried Wilhelm Leibniz began pondering the possibility of machines thinking like humans. They discussed the human mind in terms of a complex machine, laying the groundwork for computational thinking.

The Formal Birth of AI (1950s – 1960s)

The actual term “Artificial Intelligence” was first used in 1956 by John McCarthy, a young assistant professor at Dartmouth College, who organized a pivotal conference – now considered the birth of AI as a field of study. 

This event, known as the Dartmouth Summer Research Project on Artificial Intelligence, brought together researchers interested in neural networks, the study of intelligence, and the possibility of replicating human thought in machines.

During this era, AI research received significant attention and funding. Early successes included programs that could perform algebraic equations and play checkers at a high level. These developments led to optimistic predictions about AI’s future, setting high expectations for rapid progress.

The First AI Winter (1970s)

Despite early enthusiasm, progress in AI research did not keep pace with expectations. By the mid-1970s, the limitations of existing AI technology became apparent, leading to the first AI Winter, a period marked by reduced funding and waning interest in AI research. This downturn was largely due to the overly ambitious expectations that could not be met by the technology of the time, which struggled with real-world applications.

The Resurgence and Rise of Machine Learning (1980s – 1990s)

AI experienced a resurgence in the 1980s, thanks in part to the adoption of machine learning. Instead of trying to directly encode AI with extensive knowledge and rules about the world, researchers focused on creating algorithms that could learn from data. 

This shift was significant, leading to more robust and adaptable AI systems. The introduction of backpropagation by researchers such as Geoffrey Hinton allowed neural networks to learn from their errors, improving their performance over time.

During this period, governments and industries began investing heavily in AI again, intrigued by its potential applications. AI started to be used for logistics, data management, and within expert systems in fields like medicine and engineering, marking its transition from a purely academic pursuit to a practical tool in business and other areas.

Artificial Intelligence (AI) has made significant strides in many fields, and art creation is no exception. AI art generators, like those powered by machine learning models such as DALL-E or GANs (Generative Adversarial Networks), can create stunning images that dazzle the imagination. 

These tools are used for everything from generating abstract art for digital spaces to crafting backgrounds for games and virtual realities. Despite their capabilities, these AI systems often struggle with a peculiar challenge: drawing human hands accurately. 

Our article will explain why AI art generators frequently produce hands that look awkward, distorted, or downright eerie, and why hands are a particularly tough challenge for AI. Read on to know why AI finds hands so difficult to get right, and why this matters more than you think for the future of AI-generated art.

Why AI Struggles With Generating Human Hands

Human hands are one of the most complex and detailed parts of the body, involving a wide range of motions and configurations that can express a multitude of gestures and actions. This complexity presents a significant challenge for AI image generators, not just for one but for several reasons.

Below, you’ll find why AI art generators struggle with drawing hands.

High Variability

Hands are highly variable in their appearance and position. They can interact with numerous objects, appear in countless poses, and each hand gesture can convey different emotions or actions. 

For AI, which learns from a dataset of existing images, the immense variability of hand positions and their interactions with other objects can lead to a lack of comprehensive learning material. As a result, the AI often struggles to accurately recreate hand positions that it hasn’t encountered frequently in its training set.

Intricate Detailing

The structure of a hand is intricate, with fine detailing in the knuckles, nails, and skin texture. Each of these details needs to be rendered accurately for a hand to look realistic. 

AI systems typically generate images based on patterns they have learned from data; if the details in the training images are not diverse or detailed enough, the AI will have difficulty replicating them accurately. This often results in hands that look flat, malformed, or overly simplified.

Complex Interactions

Hands are rarely seen in isolation; they are usually interacting with objects or other parts of the body. This interaction adds a layer of complexity to the image generation process. 

AI must not only generate the hand but also understand and replicate how it interacts with its environment. This requires an understanding of physics, space, and object dynamics, which are challenging for AI to learn completely.

Data Limitations

The quality of the data used to train AI significantly impacts its output. If the dataset is not diverse enough or lacks high-quality images of hands in various poses and interactions, the AI will struggle to generate high-quality images of hands. 

Moreover, biased or insufficient training data can lead to repetitive errors, such as consistently generating an incorrect number of fingers or unrealistic hand shapes.

Other Parts of the Human Body AI Struggles to Generate

While AI’s difficulties with generating realistic human hands are well-documented, this challenge extends to other complex parts of the human body as well. Features such as faces, feet, and hair also present significant hurdles for AI image generators. 

The reasons for these struggles often overlap with some of those seen in hand generation. Let’s explore why AI particularly struggles with these features.

Faces

The human face is a centerpiece of identity and expression, involving subtle micro-expressions that convey a wide range of emotions, from joy to sorrow. AI often struggles to replicate these nuances for several reasons:

• Complexity of Expressions: Human expressions involve small, often rapid changes in facial muscles. AI systems find it challenging to capture these nuances accurately because they require an understanding of how muscles interact and how expressions change dynamically over time.
• Symmetry and Proportions: Human faces have a specific symmetry and proportion that can be difficult for AI to replicate accurately. Even slight deviations in symmetry or proportions can make a face look unnatural or unsettling.
• Eye Detailing: The eyes are particularly expressive and detailed parts of the face. AI systems often struggle to render the depth and sparkle of human eyes, which are critical for a face to appear lifelike and relatable.

Feet

Like hands, feet are complex structures that involve many small bones, joints, and types of movements. AI struggles with feet for similar reasons:

• Variability in Position: Feet can appear in numerous positions depending on the body’s actions, such as standing, running, or resting. Capturing these positions accurately, along with the associated shadows and textures, is challenging for AI.
• Interaction with Surfaces: Feet often interact with various surfaces, which can affect their appearance. AI must understand and replicate these interactions, such as the flattening of the soles when standing or the arching of the toes when walking, which is a complex task.

Hair

Hair presents another significant challenge for AI due to its fluid and dynamic nature:

• Texture and Flow: Hair has different textures and styles that can change with movement and environmental conditions, such as wind or humidity. AI systems often struggle to generate hair that looks natural and flows realistically.
• Volume and Light Interaction: Accurately rendering how hair volumes interact with light and shadow is complex. Hair also has varying degrees of transparency and reflectivity, which are difficult for AI to replicate, often resulting in hair that looks either too heavy or too light.

All of these features require a deep understanding of human anatomy, the physics of light and materials, and the subtleties of human expression, all of which are areas where AI still has room for improvement. 

As AI technology evolves, the ability to handle these complex human features with greater accuracy will continue to grow, driven by advances in machine learning models, increased computational power, and more extensive training datasets. 

These improvements will help AI overcome its current limitations, allowing for more realistic and nuanced representations of human features in digital art and other applications.

How to Help AI Get Human Features Right

If you’re using AI and tired of it not getting parts of the human body right, there are a few things you can do to fix this – or at least make it easier for the AI to generate better-looking images.

Here are several practical steps that can help improve the accuracy of AI-generated human features:

Use High-Quality, Detailed Images

The quality of images used in training datasets significantly impacts AI’s output. High-resolution images that show detailed features of hands, facial expressions, and interactions can provide the AI with a better understanding of subtle details. This is particularly crucial for intricate parts like the texturing of skin, the way light plays on muscle, or the specifics of hand positioning.

Implement Advanced Modeling Techniques

Employing advanced neural network models that focus on depth and texture can aid in generating more realistic human features. Techniques such as Generative Adversarial Networks (GANs) have been particularly successful in creating photorealistic images. These models learn to simulate fine details more accurately by pitting two neural networks against each other: one generates images; the other evaluates their realism.

Community Feedback

The AI development community can be a tremendous resource. Platforms like Reddit often feature discussions where users share their experiences with different AI tools, providing insights into common issues and potential solutions. By engaging with these communities, you can find solutions to your common problems with AI-generated images.

AI Is Getting Better at Generating Images Every Day

Despite the current challenges, AI technology is improving rapidly, and the quality of images it can generate is getting better every day. Developers are continually working on refining AI algorithms, expanding training datasets, and incorporating user feedback into the development process. These efforts are gradually overcoming the difficulties AI faces with complex human features like hands, faces, and hair.

Several AI tools are already making significant strides in this area. For instance, newer versions of AI image generators have begun to show improved capability in handling human anatomy with greater accuracy. These advancements suggest a promising future where AI can not only match but potentially exceed human capabilities in creating detailed, realistic images.

As AI continues to evolve, it holds the potential to transform artistic creation, offering tools that augment human creativity with digital precision.
