ReSEARCH WORK

Welcome to my comprehensive research portfolio, showcasing a collection of studies that explore the intersection of technology, education, and human well-being.

 

My work spans across multiple domains, with a focus on understanding how emerging technologies like Mixed Reality and smartphones influence learning outcomes, user behavior, and overall mental and physical well-being.

​

Each study contributes to the broader understanding of how technology shapes our experiences, interactions, and well-being. Whether you are an educator, researcher, or technology enthusiast, I invite you to explore these findings and their potential applications in designing user-centric technological solutions.

Touch and Type: Assessing the Impact of Virtual Keyboard Size on Typing Efficiency

This study examines how virtual keyboard size affects typing performance by comparing an iPhone (small keyboard) and an iPad (large keyboard). Using a within-subjects design with 9 participants, the research measured typing speed (WPM), accuracy, and consistency.
 

Findings revealed that participants typed faster and with greater consistency on the smaller iPhone keyboard, while accuracy remained similar across both devices. Despite the larger screen of the iPad, users reported greater comfort and ease of use with the iPhone, likely due to familiarity.
 

These results challenge the assumption that larger keyboards enhance typing efficiency, suggesting that device familiarity plays a more significant role. The study offers insights into optimizing virtual keyboard design for touchscreen devices.

Insights of Smartphone Usage Across Generations

This research explores generational differences in smartphone usage through interviews with individuals aged 18 to 65. Key findings show:
 

  • Younger users (18-24) use smartphones heavily for social media, entertainment, and creativity.

  • Middle-aged users (25-54) prioritize practical functions, such as organization and productivity.

  • Older adults (55+) focus on basic communication but face challenges with new interfaces and smaller screens.
     

The study used qualitative thematic analysis to uncover these trends, offering insights into the diverse needs of users from different generations. It highlights the importance of designing customizable, age-inclusive smartphone interfaces that cater to varying preferences and skills.​

Assessing the Influence of Smartphone Screen Time on User Well-Being

This study explores the link between smartphone screen time and well-being, focusing on mental health, sleep quality, stress, and life satisfaction.

Data from 39 participants, collected via an online survey, revealed that:​

  • Increased screen time is associated with higher stress, poorer sleep, and more depressive symptoms.

  • Social media usage, in particular, was linked to negative well-being outcomes.

  • However, purposeful smartphone use, especially for work, can have neutral or positive effects.
     

This research highlights the complexity of smartphone screen time's influence on well-being and underscores the need for balanced digital habits.

Impact of Mixed Reality on STEM Learning Outcomes

This study investigates the effectiveness of Mixed Reality (MR) in improving STEM education. Using the Apple Vision Pro platform, it compares MR-based learning with traditional methods, focusing on knowledge retention and spatial awareness. Key objectives include:

​

  • Assessing whether MR enhances engagement and understanding of complex STEM concepts.

  • Measuring the impact of MR on learning outcomes in comparison to conventional methods.

  • Exploring the potential for MR to transform STEM education through interactive and immersive learning experiences.
     

The findings are expected to provide insights for educators and developers to design MR tools that cater to the specific needs of STEM education, promoting more effective learning environments.
