Beyond traditional manuals: A comparative analysis of instruction manual effectiveness in handheld consumer products

Modern consumer products often come with instruction manuals that play a crucial role in guiding users through their complexities. However, a widespread lack of enthusiasm among consumers to engage with these manuals is rooted in negative experiences. This research evaluated the usability and effectiveness of traditional paper-based instruction manuals versus the redesigned version, using the HS210 drone as a case study. Employing a dual-phase methodology, this study first conducted a thorough analysis of the HS210 drone's existing paper manual, identifying its strengths, weaknesses, and user perceptions. The subsequent phase entailed the creation and evaluation of an improved manual informed by initial findings. This comparative analysis sought to measure user performance, experience, and preference regarding both the original and redesigned instruction manuals, aiming to enhance engagement and effectiveness in drone operational guides. Data collection utilized a comprehensive methodological approach, incorporating contextual inquiry, think-aloud protocols during usability tests, a pre-test survey, and post-test semi-structured interviews. The findings revealed a pronounced preference for multimedia instruction manuals, showcasing higher levels of user satisfaction, better engagement with the manuals, and significantly enhanced usability. This research underscored the potential of innovative instructional design in improving user interaction with complex consumer products. This research holds substantial potential to advance our understanding of instructional materials' effectiveness in the context of technological products. As technology becomes increasingly integrated into everyday life, the ability to effectively use and understand technological products is crucial. This study will contribute to this understanding by identifying the most effective ways to guide users in navigating new technologies, thereby reducing the frustration and time often associated with learning new devices. Moreover, the findings from this research could significantly benefit businesses and educators by providing evidence-based recommendations for instructional material design. For businesses, this means creating more user-friendly manuals that could lead to increased customer satisfaction and reduced the need for customer support

Gaze-augmented manual interaction

This project will demonstrate a new approach to employing users gaze in the context of human-computer interaction. This new approach uses gaze passively in order to improve the speed and precision of manually controlled pointing techniques. Designing such gazeaugmented manual techniques requires an understanding of the principles that govern the coordination of hand and eye. This coordination is influenced by situational parameters (task complexity, input device used, etc.), which this project will explore in controlled experiments
