ZipCrit: SketchAR
Short Design Critique for SketchAR app for SI 559: Introduction to AR/VR course at University of Michigan
Introduction of the feature in focus
SketchAR is an application with personalized drawing courses. This ZipCrit will be focused on the design critique of the app’s AR Drawing feature. AR Drawing enables users to:
choose a sketch to draw and the app will guide you through the sketching process, or
upload your sketches and the application will provide an AR projection of the sketch on paper and you can outline it.

I like: Automatic Flashlight Activation for Improved Drawing Visibility
The app adapts to varying light conditions in the user’s room and automatically activates the phone's flashlight when the lighting drops below a certain threshold. I like that the app considers environmental changes that impact the user’s experience and provides an effective solution. Pictures below show that feature in the work.
The light level icon above the left image indicates that the room’s lighting is moderate, allowing drawing to proceed without additional light. On the right, the icon turns orange, signaling poor lighting conditions, and the app automatically activates the flashlight.
I like: Adjusting Image to Drawing Alignment After Camera Movement
The app accounts for hand movements when the user holds the phone above the canvas for AR drawing. If the phone shakes or moves, the app allows the user to manually realign the drawing to the canvas when they resume. I like how the app adapts to physical changes during use, enhancing the user’s experience. The images below demonstrate this feature in action.
The image on the left shows that the camera has shifted due to the hand movement, causing the lines to be misaligned with the drawing. The image on the right shows the lines after they have been manually adjusted to match the physical drawing.
I wish: Visual cues with information about the drawing were more intuitive
The app’s visual cues in AR Drawing view could be more noticeable, especially as they offer helpful storytelling elements or guidance, like “try switching brushes” or “let’s add more details now.” Currently, these cues are located at the very top of the AR Drawing screen, however, users’ attention is primarily on the lower part of the screen where the main action occurs, making these cues easy to miss and potentially reducing their effectiveness.
