The Echo Smartpen is used to take notes in class while recording the lecture. The audio is synced with the notes as they’re being written. The user can tap notes with their pen to hear the audio that corresponds to that section of notes. The synced audio and notes can be transferred to the user’s computer, where they can listen to the audio by section, sort and save notes, and search for specific words in the handwritten notes.
Digital recorders can be used to record audio and listen back at later times. CSDTech has several of these devices available for students to loan.
