#### 🎓 Thesis Title
**"Improving Crowdsourcing-based QoE Studies for Point Clouds via Interaction Incentives"**
---
### 🧠 Summary
Point clouds serve as the digital foundation for numerous modern technologies, including:
- **Autonomous driving**
- **Manufacturing applications**
- **Virtual Reality (VR)**
In VR, point clouds enable highly immersive and realistic environments due to their spatial accuracy. This allows users to engage more naturally, and industries—such as manufacturing—benefit by simulating environments for training, maintenance, and operation without real-world risks.
> 💡 **Example**: A virtual training module where a trainee practices machinery maintenance using point cloud-rendered equipment.
However, **despite their potential**, widespread adoption of point cloud applications in VR is limited due to:
- **Poor user experience**
- **Low perceived quality**
- **Hardware limitations**
- **Bandwidth constraints**
These limitations often lead to **point cloud size reduction techniques**, which, while improving performance, negatively affect user experience (QoE).
---
### ❓ Why Evaluate QoE?
To ensure a good user experience, **user-centered evaluations** are essential.
Yet, technical metrics **alone do not reflect true user satisfaction**.
#### 📉 Current Challenges
- QoE studies are often **costly**, **limited in scale**, and **lack quality feedback**.
- Current methods do not scale well or incentivize active user engagement.
---
### 💡 My Approach
This thesis explores the **feasibility and optimization** of using **crowdsourcing** to evaluate point cloud QoE.
#### Key Contributions:
- ✅ Designed and implemented a full **interactive point cloud QoE study** using a crowdsourcing approach.
- 🎯 Investigated how **interaction incentives** can:
- Increase user engagement
- Improve feedback quality
- Enhance overall study effectiveness
- 🔍 Analyzed whether these mechanisms result in **better and more scalable QoE evaluations**.
---
### 📈 Outcomes
- Developed a complete framework: **Design → Implementation → Deployment → Analysis**
- Demonstrated that **interactive incentives** significantly improve **participant engagement** and **data reliability** in crowdsourced QoE studies.
