—Many instructors in academic institutions rely on traditional media, like the mouse and keyboard, for controlling their multimedia presentations. This restricts the freedom of movement of the instructor during presentations thus affecting classroom management. This is also the case in Malayan Colleges Laguna. In this study, the researchers have developed SmartLITE, a tool that is able give the instructor control over the mouse using a camera-tracked laser while also giving freedom of movement during laboratory demonstrations. Using several Image Processing techniques, specifically in computer vision, the tool can track the laser and move the mouse cursor with it, as well as actuate mouse functionalities such as left, right, double click, and dragging. Put simply, it makes the traditional projection screen into an interactive laser-controlled interface. The researchers evaluated the effectiveness of SmartLITE as perceived by instructors and students in an IT laboratory setup. The two groups of respondents namely: the instructor-respondents and the student-respondents had different surveys to easily assess the data. To measure the tool effectively the researchers have identified a set of criteria to rate the tool, namely: Freedom of Movement, Student Engagement, and Communication. The questionnaires utilized Likert-scale type questions to determine the respondents’ level of satisfaction or dissatisfaction toward each criterion. Results of the survey was tallied and summarized by computing for the weighted mean average of each item. To determine the score of each criterion, the arithmetic mean of the scores of each item in a particular criterion was computed. The scores are then interpreted and SmartLITE was found to have above average scores on all criteria. From the results of the survey, it can be said that SmartLITE is not only a viable teaching tool but also effective as perceived by instructors and students.
