Abstract

Geography heavily relies on visual aids to convey various information. However, it faces significant challenges in meeting the educational needs of visually impaired students due to the lack of suitable learning resources. Traditional teaching tools like globes are inaccessible and impractical for this group. These globes lack the tactile features needed to distinguish geographical elements, especially the vast continent of Asia, known as the largest continent in the world. Additionally, these globes are easily displaced, making it difficult for visually impaired students to accurately identify countries, often requiring continuous verbal assistance from teachers. The primary objective of the current research initiative is to develop an innovative tactile globe that not only addresses these issues but also promotes inclusivity and ease of use for all students, particularly those with visual impairments, by enriching the learning experience in geography education. The design concept is based on a thorough analysis of identified challenges and relevant literature, offering a comprehensive solution to existing limitations. Key features of this design include a Raspberry Pi as the controller, a stepper motor as the moving mechanism that allows the globe to rotate along the x-axis, mimicking the Earth's rotation, specific buttons corresponding to different areas within the continent of Asia, integrated speakers for auditory feedback, and distinct indicators associated with each button to enhance usability. The selection of components and functions aligned with the research goals is crucial to ensure the development of a truly transformative educational tool. Experiments were conducted to evaluate the prototype, and post-experiment questionnaires were administered to volunteers consisting of both normal and disabled students to record their experiences. The questionnaire included five elements: usability, ease of use, attitude towards use, behavioral intention to use, and enjoyment. During the experiment, time data was collected to assess the system's effectiveness throughout the experiment. Survey results showed an average score of 4.7 for efficiency, 4.9 for ease of use, 4.6 for confidence, 5.0 for recommendation, and 5.0 for enjoyment. Calibration results also indicated that the motor took only 4.72 seconds to move from the origin to each area in the continent of Asia. Overall, this research project lays a solid foundation for the development and implementation of more effective learning tools for all students, regardless of their health status.
