Interaction history Introduction and eye-tracker Context (2/2) Z´ ephyrin Soh Introduction Context Background Motivating Example Related Work Program Exploration Research Trends Limitations of Previous Work There are three research trends on program comprehension: Research Questions ◮ Theories: process, knowledge, model. RQ1: Exploration Strategies and Program Structure RQ2: Exploration Strategies ◮ Factors: program, developer, task. and Triggers RQ3: Exploration Recommender ◮ Exploration: developers’ behavior, task. RQ4: Maintenance by Analogy We focused on the exploration trend. Preliminary Results Feasibility Study Research Plan Conclusion 4 / 28

Interaction history Introduction and eye-tracker Background (1/2) Z´ ephyrin Soh Introduction Program Exploration Context Background Two main concepts: Motivating Example Related Work ◮ Interaction history : a sequence of interaction events Program Exploration Limitations of Previous that describe accesses of and operations performed on a Work Research program’s artifacts within a user’s IDE [2]. Questions RQ1: Exploration Strategies ◮ Task context : the program elements and relationships and Program Structure RQ2: Exploration Strategies relevant to completing a particular task [3]. and Triggers RQ3: Exploration Recommender We focus on the interaction histories build by the Mylyn RQ4: Maintenance by Analogy Eclipse plugin: Industrial tool and use by all Mylyn Preliminary Results contributors.

Interaction history Introduction and eye-tracker Background (2/2) Z´ ephyrin Soh Introduction Eye-tracker System Context Background ◮ Eye-tracker : device used for measuring eye Motivating Example Related Work movements [4]. Program Exploration Limitations of Previous ◮ Eye movement data allow to know the observer’s visual Work Research attention (focusing on a particular location). Questions ◮ Eye-tracker collects two types of eye-gaze data: RQ1: Exploration Strategies and Program Structure RQ2: Exploration Strategies ◮ Fixation : stabilization of the eye on an object of and Triggers RQ3: Exploration interest for a period of time. Recommender RQ4: Maintenance by ◮ Saccade : movements of the eye from one fixation to Analogy another. Preliminary Results Feasibility Study Research Plan Conclusion [4] A.
