The challenge and application development goals

The client approached our company with a clear vision for an edtech app: to create an interactive, feature-rich, e-learning book on Kyokushin karate at an affordable cost. Beginners often feel overwhelmed by the complexities of the techniques. Even simple movements engage multiple muscles, making it difficult to track on their own.

Our firm's task was to develop a detailed, visual, and interactive mobile book, complete with guidance, images, video lessons, and personalized advice. The goal was to make e-learning with an app as seamless and intuitive as a live class. Users should gain a comprehensive understanding of their muscle activity during training to perform techniques correctly.

The edtech app's interface and features

Our company's developers tackled the challenge by focusing on two key areas: creating intuitive mobile UI/UX design and building responsive, seamless functionality for the e-learning app. It quickly became clear that the app would need to handle large volumes of data, including text, images, and videos.

To ensure the app remained fast and lightweight, we compressed all these files efficiently. The app's features had to be sophisticated yet straightforward, making it easy to navigate even for first-time online learners.

3D body model

All techniques are visualized with a 3D animated character, allowing users to zoom in on the skeleton, muscles, circulatory, and nervous systems, and view internal organs. The edtech app shows techniques from both an external viewpoint (like a mirror) and an anatomical perspective. To build this feature, we integrated and compressed thousands of 3D images, researched anatomical structures, and created detailed representations of the human body.

To achieve this, we integrated and compressed thousands of 3D images, researched anatomical structures, and worked on detailed representation of the human body.

Image rendering

Our company's team developed a custom image rendering system to enable the seamless upload of additional e-learning content. This system reduces the size of the app's multimedia content, improving storage efficiency and ensuring quick access to requested files. We also tested and optimized CPU performance to minimize resource waste.

Multimedia pages

The app was built to provide access to 4,500 pages featuring techniques, anatomical descriptions, real-time representations, proverbs, and motivational quotes. Combining theoretical models, practical advice, and encouraging content, App Kanku offers a comprehensive e-learning approach.

Responsiveness

We adapted the app's UI/UX design for iOS and Android smartphones and tablets. Ensuring that all text and multimedia content displays correctly in various sizes and orientations, we created multiple screens for a single multimedia page.

Content categories

The application contains various content types essential for efficient Kyokushin e-learning. Essentially, it's multiple solutions in one comprehensive app.

  1. One category focuses on organizing the training environment, preparing clothes and belts, and following the main principles of martial arts. Users can also learn Japanese numbers and explore the writing system.
  2. Another app's category covers basic techniques, such as stances, using hands and legs, practicing breathing, and understanding necessary anatomy.
  3. A third category is dedicated to complex techniques for intermediate and advanced learners familiar with the basics.

For each category, our agency developed different ways of displaying content. Some focus on 3D displays of the learner's body, while others feature extensive images and text. Our UI/UX designers analyzed user needs for each app's category to find the optimal combination of multimedia materials.
