Depending on the rendered haptic property and the required feedback fidelity, these can be complex estimates of the contacts (points, forces) and object properties (shape, material, mass, deformation, etc.). Computational and rendering models are also needed to render the virtual visual and haptic stimuli to the user. -While \ThreeD visual rendering is mature, rendering haptic properties still faces many research challenges, especially for wearable haptics \cite{pacchierotti2017wearable,culbertson2018haptics}. +While \ThreeD visual rendering is mature, rendering haptic properties still faces many research challenges due to the complexity of the human touch \cite{pacchierotti2017wearable,culbertson2018haptics}. However, a balance has to be found between the perceptual accuracy of all models used and the real-time constraints of the interaction loop. \section{Research Challenges of Wearable Visuo-Haptic Augmented Reality}
