Getting Started

SketchStudio is a Web-based prototyping tool for 2.5D animated scenarios. SketchStudio enables to create and represent design ideas involving multiple artifacts and people.


Spatiotemporal Timeline
New Way to Specify Dynamic Attributes

SketchStudio has differnt interface with existing video-editing tools. It creates a node graph of human's journey on the plane that has axes of time and space. Each node represents that human interacts with which spatial object at which moment.

A Sketch World Changing over Time

SketchStudio involves two types of sketch planes, permanent Main Sketch and changable State Sketch. State Sketch superimposes onto the Main Sketch. This configuration is applied to both human and object.

Dynamic Behavioral Representations

SketchStudio supports keyframe-based action making. It enables simple action recording with touch and drag as well as detail manipulation with rotating skeletons. Created actions are played when the assinged nodes are activated.

Parallel Universe
Exploring Various Alternatives

SketchStudio provides parallel universes to explore various alternative scenarios. Each universe involves separated node graphs and sketches. While playing, the activated universe can be decided using Shift.

Immersive Scenario Playback

SketchStudio enables users to experience indirectly. It supports immersive experience of sketch world with chasing specific human or VR mode using Google Cardboard VR.
