FlipMe Learning Companion

Online Learning Companion

FlipMe is an IoT companion designed to promote active and interactive online learning by augmenting peer-to-peer interaction in real-time. Through a user validation study, FlipMe's tangible interfaces and embodied feedback, such as the flipping book metaphor, were found to promote interaction between paired peers during online learning activities. This unique approach enhances communication for students compared to conventional online learning services that primarily rely on textual information through discussion boards.

FlipMe was realized using various fabrication techniques, including 3D printing and computer numerical control (CNC), to create a high-fidelity prototype that closely approximates the aesthetic and functional characteristics. The design incorporates ash wood for its natural beauty and CNC machining to ensure durability. The flipping card mechanism utilizes a polycarbonate sheet and a small aluminum needle for holding and releasing the cards. The rotation of the cards is achieved through a timing belt and a pulley system powered by a step motor. The handle includes a rotary encoder module to sense rotations and transmit the same pattern and number of rotations to a paired FlipMe product.

The physical dimensions of FlipMe are 100mm (width) x 100mm (depth) x 144mm (height), with an inclination of 86° for easy observation of the main interfaces. The mobile application design is optimized for the latest iPhone models, with portrait and landscape views of 1125x2436 px and 2436x1125 px, respectively.

FlipMe's unique design features and functionality make it an ideal tool for online learning. The flipping top provides real-time feedback through a book-like motion triggered by a paired peer's viewing of video content. Group study activities are expressed through a rolling ball feedback, and the rotatable handle enables nudging for peer-to-peer interaction. By conveying information in a more memorable and intuitive way, FlipMe enhances the online learning experience beyond traditional screen-based interfaces.

The FlipMe project was conducted at UNIST (Ulsan National Institute of Science and Technology) in the Republic of Korea from March 2018 to February 2019. The design was supported by a research study that evaluated FlipMe's potential to stimulate peer-to-peer communication during online video content engagement. The study involved 22 participants and provided insights into the effectiveness of tangible interfaces in promoting active engagement in peer learning activities.

FlipMe has been recognized for its innovative design and practicality, receiving the Iron A' Design Award in the Education, Teaching Aid, and Training Content Design category in 2019. This prestigious award acknowledges FlipMe's integration of industry best practices, competent technical characteristics, and its contribution to a better world.
