Core Concepts
A novel approach using genetic algorithm-based support vector machine to extract and score key usability features of a mobile learning application as per user requirements.
Abstract
The study proposes a novel approach for intelligent usability assessment of mobile learning applications. It involves the following key steps:
Collecting user feedback and requirements regarding the usability of a mobile learning application (in this case, the LMS-IUB application) through a questionnaire-based survey.
Extracting key usability features (efficiency, effectiveness, ease of use, learnability, memorability, cognition, and consistency) from the user feedback data.
Scoring the extracted usability features using a genetic algorithm-based approach. The genetic algorithm is used to optimize the scoring of the features based on user requirements.
Applying a GA-based support vector machine model to cluster and classify the usability features based on their importance and quality.
Ranking the usability features into categories like "very good", "good", "fair", and "average" based on the scoring and classification results.
The proposed approach provides a systematic and intelligent way to assess the usability of mobile learning applications from the user's perspective. It helps identify the key usability issues and prioritize them for improving the overall user experience.
Stats
The study used a sample of 200 students from the Islamia University of Bahawalpur to collect user feedback on the usability of the LMS-IUB mobile application.
Quotes
"In the field of human computer interaction (HCI), the usability assessment of m-learning (mobile-learning) applications is a real challenge."
"There is neither any theory nor any tool available to measure or assess a user's perception and assessment of usability features of a m-learning application for the sake of ranking of the graphical user interface of a mobile application in terms of a user's acceptance and satisfaction."
