Title
Evaluation of educational applications in terms of communication delay between tablets with Bluetooth or Wi-Fi Direct.
Abstract
This study conducted a survey to implement educational applications that can share information even in environments where access points cannot be used. In particular, we investigated whether Bluetooth (widely used for many years) or Wi-Fi Direct (developed recently) is more suitable when creating educational applications using an ad hoc network. To survey the influence of hand movements on delay time while operating tablets, we created a paint application that shares a drawing screen across two tablets and conducted an experiment. In addition, to survey the influence of human presence on delay time, we conducted an experiment in which we changed the number of students seated between the two tablets in the classroom. From the results of these experiments, we conclude that Bluetooth is less influenced by hand movements and human presence than Wi-Fi Direct. We also verified the practicality of educational applications using Bluetooth communication. We developed an educational application, and students used the application in their actual class. A questionnaire to investigate whether they were conscious of communication delay was administered.
