The proposed haptic interaction techniques can be extended to support more complex surface visualization tasks, such as data annotation and feature extraction, by integrating additional sensory modalities and enhancing the haptic feedback mechanisms. For instance, incorporating a multi-layered haptic feedback system could allow users to feel different textures or resistance levels corresponding to various data attributes, thereby enriching the interaction experience.
To facilitate data annotation, the haptic stylus could be equipped with contextual feedback that changes based on the type of data being annotated. For example, when hovering over a critical feature, the haptic feedback could intensify, signaling the user to take action. Additionally, implementing a snapping mechanism that not only guides the stylus to the surface but also highlights specific regions of interest could streamline the annotation process.
For feature extraction, the haptic interaction could be enhanced by allowing users to "pull" or "push" features from the surface, with the haptic feedback providing resistance that mimics the physical effort required to manipulate complex data structures. This could be achieved through customizable force profiles that adapt based on the complexity of the surface features being interacted with, thus providing a more intuitive and efficient means of extracting relevant data.
