  Drawing is an art that enables people to express their imagination and
emotions. However, individuals usually face challenges in drawing, especially
when translating conceptual ideas into visually coherent representations and
bridging the gap between mental visualization and practical execution. In
response, we propose ARtVista - a novel system integrating AR and generative AI
technologies. ARtVista not only recommends reference images aligned with users'
abstract ideas and generates sketches for users to draw but also goes beyond,
crafting vibrant paintings in various painting styles. ARtVista also offers
users an alternative approach to create striking paintings by simulating the
paint-by-number concept on reference images, empowering users to create
visually stunning artwork devoid of the necessity for advanced drawing skills.
We perform a pilot study and reveal positive feedback on its usability,
emphasizing its effectiveness in visualizing user ideas and aiding the painting
process to achieve stunning pictures without requiring advanced drawing skills.
