NinjOrAItor

Introduction to NinjOrAItor, an AI Video Analysis Platform

"NinjOrAItor" is an innovative AI platform  designed to enhance English oral presentation skills among students in Hong Kong by providing AI feedback on video presentations, opportunities for practice, and targeted learning modules to address common pronunciation challenges. Through the integration of advanced technology and educational expertise, NinjOrAItor offers a unique, student-centred approach to language learning.

With NinjOrAItor, students can analyse their recorded presentation videos in the One Button Studios and receive valuable insights into various aspects of their delivery, including clarity, content, appropriateness, pronunciation, intonation, eye contact, facial expressions, hand gestures, and other key presentation skills. This empowers students to recognise their strengths and identify areas for improvement, helping them build effective communication skills essential for academic success.

   • Use the iPad to adjust the camera position.
     
      
   • Ensure the audio output device is set to “Speaker (RealTek® Audio)” and the input device is set to “Microphone (USB Audio Device)”. Then, start recording your video.

3. AI Analysis

   • Click the "AI Analysis" button to review the analysis once the Status is shown as “Submitted”. Otherwise, the result will not be displayed, and you will need to re-upload your video.
