Abstract
We propose a solution for generating dynamic heightmap data to simulate deformations for soft objects, with a focus on the human skin. The solution utilizes mesostructure-level wrinkles and procedural textures to add static microstructure details. It offers flexibility beyond human skin during animations to mimic other material deformations, such as leather and rubber. Various methods suffer from self-intersections and increased storage requirements during synthesizing wrinkles. Although manual intervention using wrinkles and tension maps offers control, it lacks information on principal deformation directions. Physics-based simulations can generate detailed wrinkle maps, but may limit artistic control. Our research presents a procedural method to enhance the generation of dynamic deformation patterns, including wrinkles, with better control and without reliance on captured data. Incorporating static procedural patterns improves realism, and the proposed approach can be used in other application areas.

Abstract
Objectives: The purpose of this study was to field-test a recently developed AR-based serious game designed to promote SSE self-efficacy, called Spot. Methods: Thirty participants played the game and answered 3 questionnaires: a baseline questionnaire, a second questionnaire immediately after playing the game, and a third questionnaire 1 week later (follow-up). Results: The majority of participants considered that the objective quality of the game was high, and considered that the game could have a real impact in SSE promotion. Participants showed statistically significant increases in SSE self-efficacy and intention at follow-up. Of the 24 participants that had never performed a SSE or had done one more than 3 months ago, 12 (50.0%) reported doing a SSE at follow-up. Conclusions: This study provides supporting evidence to the use of serious games in combination with AR to educate and motivate users to perform SSE. Spot seems to be an inconspicuous but effective strategy to promote SSE, a cancer prevention behavior, among healthy individuals. Practice implications: Patient education is essential to tackle skin cancer, particularly melanoma. Serious games, such as Spot, have the ability to effectively educate and motivate patients to perform a cancer prevention behavior.
