Literature Review

Org Mode Studies

"Org Mode as Knowledge Management System"   paper

Abstract

This paper explores the use of org-mode for personal knowledge management.

Key Findings

• Structured text improves information retrieval
• Hierarchical organization aids comprehension
• Plain text format ensures longevity

Methodology

The study involved 50 participants using org-mode for 6 months.

Data Collection

• Weekly surveys
• Usage analytics
• Interview sessions

Analysis

Statistical analysis revealed significant improvements in:

1. Information organization
2. Task completion rates
3. Note-taking efficiency

"Tree Visualization of Hierarchical Data"   paper

Research Question

How do different tree visualization methods affect user comprehension?

Experiments

Experiment 1: Static vs Interactive Trees

Interactive trees showed 23% better comprehension scores.

Experiment 2: Vertical vs Horizontal Layout

No significant difference in comprehension, but users preferred vertical layout.

Data Analysis

User Feedback

Survey Results

Satisfaction Ratings

• Ease of use: 4.2/5
• Visual clarity: 4.5/5
• Performance: 3.8/5

Common Requests

1. Better mobile support
2. Collaborative editing
3. Integration with other tools

Usability Testing
