Corrective Instruction Generation for Motion Improvement
Introduction
In the world of sports and fitness, getting the right move is essential. Think of it like trying to dance but stepping on your partner's toes. Nobody wants that! This is where corrective instructions come in handy. They are like friendly reminders to help you correct your movements so that you don't end up looking like a confused robot. Recent developments in technology have made it possible to create systems that generate these corrective instructions using advanced computer models.
The Need for Corrective Instructions
When people learn a new skill, especially physical ones like sports, they often need guidance. Without feedback, learners might adopt bad habits or do moves that are not safe, like trying to lift weights with the wrong posture. These mistakes can lead to injuries and slow down the learning process. As more people use motion-sensing technology in sports, the demand for smart systems that can guide users is on the rise.
Motion Corrective Instruction Generation Explained
Imagine being able to take a video of yourself playing basketball, and then receiving specific tips on how to improve your shot. This is what motion corrective instruction generation aims to do. It involves creating text-based instructions that help users adjust their physical movements. By using what we know about how humans move, we can provide better feedback for sports coaching, rehabilitation, and skill learning.
How it Works
The process starts with analyzing a person's current movement – let’s call it the "source motion." Then, we establish an ideal movement – the "target motion." The system generates instructions to help the user transition from the source to the target motion. It's a bit like taking a map that shows your current location and guiding you to your favorite ice cream shop.
To make these instructions, we use Large Language Models, which are like fancy text generators that can understand and produce human-like text. We collect data by editing and generating motions based on examples, creating a set of triplets that includes the source motion, the target motion, and the corrective instruction.
Data Collection Through Motion Editing
Getting the right information for generating instructions is crucial. Traditionally, collecting data meant hiring experts to record and analyze movements, but that can take a lot of time and is expensive. Instead, we can use motion editing techniques to gather large datasets more efficiently. Think of it as having a robotic assistant that can quickly generate the necessary information without needing a coffee break!
By utilizing pre-trained motion models, we can collect data that tells us how to edit movements. This way, we can easily create pairs of motions and their corresponding corrective instructions without having to rely solely on people to give their feedback.
Using Motion Editing Models
The motion editing model is like a talented puppet master, capable of modifying movements accurately. It takes a motion sequence and adjusts it based on corrective instructions. This means if someone isn’t doing their yoga pose correctly, the model can tweak the movements to show the proper pose.
The editing process involves adding noise and cleaning it up, which may sound like a chaotic party, but trust us, it results in smoother and better movements!
Fine-Tuning Large Language Models
Once we have the data ready, we fine-tune our language models to ensure they can generate effective corrective instructions. This is a bit like teaching a toddler how to speak – they need plenty of examples to learn the words and phrases properly.
We use the gathered triplet data to train the models to associate specific movements with clear instructions, so when a user performs a certain action, they receive the right guidance. This is how the magic of communication between movement and text happens.
Evaluation of Instructions
Once the instructions are generated, it’s important to check how good they are. We measure their quality by looking at how closely they match human-made instructions and how clearly they direct the user to improve their movements. It's like comparing your mom's famous chocolate chip cookies with the store-bought ones — you want the best!
To assess the accuracy of the generated instructions, we also look at how well the users can perform the target movements based on the generated guidelines. After all, the goal is to not just sound smart in writing but also be effective in changing the way people move!
Comparing Different Methods
In the quest for the best corrective instruction generator, we compare our method with others. Picture a sports competition where each system tries to prove it can give the best advice for improving movement. We see how our method stacks up against other large language models and motion generators.
Surprisingly, our approach often wins — like a well-trained athlete outperforming a weekend warrior. The results from various tests show that our system produces better instructions, which means people can learn and adapt their movements more effectively.
Real-World Applications
Imagine a busy gym where people are trying to get fit. Instead of relying solely on personal trainers, clients could use an app that analyzes their movements and offers immediate feedback. Our method could easily fit into such a setting, helping individuals improve their form while working out, making their sessions safer and more productive.
We also see potential in rehabilitation settings, where patients recovering from injuries can receive tailored instructions to help them regain their strength and coordination.
Limitations and Future Work
While our approach shines bright, it's not without its challenges. The dataset we create is specific and focused on certain movements, which means it might not cover every possible action someone might perform in sports.
Moreover, the current system only works with motion pairs that have the same length. Imagine trying to fit a square peg into a round hole — not going to happen! We are working on ways to overcome these hurdles to make the system even more robust.
Additionally, there is the risk that the technology could be misused. For example, it might generate inappropriate instructions if not carefully monitored, akin to letting a mischievous child run wild with a box of crayons.
Conclusion
Our work in generating corrective instructions is a step toward making sports training and rehabilitation smarter, safer, and more efficient. By blending motion editing with the latest language models, we create a system that helps users improve their physical movements, much like a personal trainer whispering guidance into the ear of an athlete.
With continued advancements, we hope to refine these instructions further and ensure they meet the highest standards, helping people become better at their craft, whether it's weightlifting, dancing, or just trying to be the best they can be!

Title: CigTime: Corrective Instruction Generation Through Inverse Motion Editing
Abstract: Recent advancements in models linking natural language with human motions have shown significant promise in motion generation and editing based on instructional text. Motivated by applications in sports coaching and motor skill learning, we investigate the inverse problem: generating corrective instructional text, leveraging motion editing and generation models. We introduce a novel approach that, given a user's current motion (source) and the desired motion (target), generates text instructions to guide the user towards achieving the target motion. We leverage large language models to generate corrective texts and utilize existing motion generation and editing frameworks to compile datasets of triplets (source motion, target motion, and corrective text). Using this data, we propose a new motion-language model for generating corrective instructions. We present both qualitative and quantitative results across a diverse range of applications that largely improve upon baselines. Our approach demonstrates its effectiveness in instructional scenarios, offering text-based guidance to correct and enhance user performance.
