Haptic Tumor Augmentation: Exploring Multi-Point Interaction

Abstract: We currently explore the application of haptic augmentation in the context of palpation training systems. The key idea is to modify real touch sensations with computed haptic feedback. In earlier work, we have introduced an algorithmic framework for determining appropriate augmentation forces during interaction at one contact point. In this paper, we present an extension of the approach to deal with manipulations at more than one contact location. At the heart of our method is the data-driven estimation of Hun… Show more

“…The system transmits vibrations and audio feedback to the user during the interaction. Jeon and Harders [44] introduced a system to operate on palpate tumors through the use of AR and haptic devices. A comparison of environments that aid learning visuo-haptically to perform surgeries and traditional forms was presented in the work of Esteban et al [45].…”

“…The haptic interaction that students have with theoretical information may be enhanced with interactive technology [4], [5]. Haptic interactive technology may facilitate hands-on laboratory content by improving learning in topics like physics [4], chemistry [6], mechatronics [7], mechanics [8], [9], electricity and magnetism [10], mathematics [11], manufacture [12], [13], and medicine [14], [15]. The need for alternative tools and methods that increase learning outcomes has driven many investigations towards enhanced learning e.g.…”

“…On the other hand, nonlinear models, such as the Hunt-Crossley model, are expected to be more accurate for describing the real behavior during the contact with soft human tissues [18,20]. However, so far nonlinear models have only been used for parameter estimation [18,21,22], but not for force control design.…”
