Challenges and Solutions

We found that conventional video recording methods for lectures were often too expensive and complicated for individual creators.

In particular, recording lecture content while taking notes required specialized equipment, platforms, and advanced editing skills, making the process difficult and costly for many users.

We wanted to break down these barriers by creating a more accessible, affordable, portable, and easy-to-use tool that would allow more creators to share their lectures online.

We developed a solution that combined a mobile device, a smartpen, and a paper controller to simplify the recording process.

Prototyping

Designing a seamless multitasking experience was one of the main challenges.

Through design research and persona interviews, we found that capturing a person's face and body language, such as hand gestures, required the camera to be positioned roughly two feet away, approximately an arm's length.

This distance also allowed users to comfortably monitor the screen. However, it made interacting directly with the touchscreen difficult. Users had to twist their bodies to reach the screen, making it challenging to control multiple buttons quickly and accurately.

PaperTube Controller

PaperTube Controller is a single sheet of paper that users can place on a desk to control multiple recording features by tapping it with the smartpen.

These features include starting and stopping recordings, adding sound effects, selecting pen colors, and zooming.

By moving these controls from the mobile device to the paper controller, creators can control recording features without reaching for the screen. This allows them to maintain the proper distance from the camera and move freely while recording their body gestures.
