      The lack of force feedback is considered one of the major limitations in Robot Assisted Minimally Invasive Surgeries. Since add-on sensors are not a practical solution for clinical environments, in this paper we present a ...
    • Sensorless force estimation using a neuro-vision-based approach for robotic-assisted surgery 

      Avilés Rivero, Angélica Ivone; Alsaleh, Samar M.; Sobrevilla Frisón, Pilar; Casals Gelpí, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference lecture
      Open Access
      This paper addresses the issue of lack of force feedback in robotic-assisted minimally invasive surgeries. Force is an important measure for surgeons in order to prevent intra-operative complications and tissue damage. ...
    • Sensory substitution for force feedback recovery: A perception experimental study 

      Avilés Rivero, Angélica; Alsaleh, Samar M.; Philbeck, John; Raventos, Stella P.; Younes, Naji; Hahn, James K.; Casals Gelpí, Alicia (2018-08)
      Article
      Open Access
      Robotic-assisted surgeries are commonly used today as a more efficient alternative to traditional surgical options. Both surgeons and patients benefit from those systems, as they offer many advantages, including less trauma ...
    • Sight to touch: 3D diffeomorphic deformation recovery with mixture components for perceiving forces in robotic-assisted surgery 

      Avilés Rivero, Angélica; Alsaleh, Samar M.; Casals Gelpí, Alicia (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Open Access
      Robotic-assisted minimally invasive surgical sys-tems suffer from one major limitation which is the lack of interaction forces feedback. The restricted sense of touch hinders the surgeons’ performance and reduces their ...
    • Sliding to predict: vision-based beating heart motion estimation by modeling temporal interactions
