This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

We meet to learn and practice American Sign Language and to grow our familiarity with Deaf culture. Facilitated by hearing folks (with a connection to a professional interpreter) using Deaf-created content. People of all ASL skill levels are welcome! As we learn, we hope to connect more with the Deaf community in Central Ohio. Join us as you're able! Come regularly or just once - whatever you're looking for! Each meetup will explore different topics related to ASL/Deaf culture, and will feature time to practice conversation with one another. Just bring yourself and a willingness to learn!

Let's get together and listen to **[Eric Rico](https://www.linkedin.com/in/ericrico/)** from Unity3D (**From Joints to Gestures: Reading Hands in Unity**). A hand tracker gives you joints, not a gesture. This talk shows how you get from raw joints to a "thumbs-up" in Unity: the pipeline that cleans up the data, how a gesture becomes a few 0-to-1 values within tolerance, and why orientation matters as much as finger shape. Includes a live demo of tuning gesture thresholds. Eric also runs the **[Columbus Unity User Group](https://www.meetup.com/columbus-unity-user-group/)**. Check it out! ***Bring your laptop and expect to write some (non-AI-generated) code!*** Food and drinks will be available. **LOCATION:** 6515 Longshore Loop, Suite 300, Dublin, OH 43017 **FREE PARKING:** 6725 Longshore Street, Dublin, OH 43017

Most people use LLMs by feel: ask a question, read the answer, decide whether it “seems good,” and move on. That works for casual use. It does not work when you are building software, automating workflows, writing important documents, or relying on AI for anything that needs to be repeatable. In this talk, we’ll look at how to improve and evaluate the inputs and outputs of LLMs using practical measurement techniques. We’ll cover how prompt changes affect results, how to compare outputs, how to build simple evaluation sets, and how math-based methods like similarity scoring can help you move beyond guesswork. This will be beginner-friendly, so even if you don't know anything about AI, you should get something out of it. However, this will be a little more technical than our intro talks. You do not need to be an AI researcher, but programmers and technically curious attendees will get a lot out of it. We’ll cover: * Why “it looks good” is not enough * How to improve prompts by changing the input, context, and constraints * How to compare LLM outputs more systematically * Basic evaluation techniques for accuracy, consistency, and usefulness * How embeddings, cosine similarity, and scoring can help evaluate results * Where automated evaluation works — and where humans still need to stay in the loop By the end, you’ll have a practical mental model for treating LLMs less like magic and more like systems you can test, measure, and improve. LOGISTICS AND PARKING: The talk starts at 7:00 PM. The first half hour is reserved for everyone to get set up and mingle. Free pizza and drinks! The cheapest parking option is to find street parking, which will only cost you a few bucks. Otherwise, park in the nearby veteran's museum lot for $8. It's highly recommended you avoid the nearby $15 garage parking.
