  1. 6. Haptic and visual simulation of material cutting process : a study focused on bone surgery and the use of simulators for education and training

    Författare :Magnus G. Eriksson; Jan Wikander; Ingela Nyström; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; surgical simulation; virtual reality; haptic feedback; surgical training; medical simulators; metrics; 3D visualization; Medical technology; Medicinsk teknik;

    Sammanfattning : A prototype of a haptic and virtual reality simulator has been developed for simulation of the bone milling and material removal process occurring in several operations, e.g. temporal bone surgery or dental milling. The milling phase of an operation is difficult, safety critical and very time consuming. LÄS MER

  3. 7. Tools in and out of sight : an analysis informed by Cultural-Historical Activity Theory of audio-haptic activities involving people with visual impairments supported by technology

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; haptic; multimodal; disability; interaction; Cultural Historical Activity Theory; open-source software;

    Sammanfattning : The main purpose of this thesis is to present a Cultural-Historical Activity Theory (CHAT) based analysis of the activities conducted by and with visually impaired users supported by audio-haptic technology.This thesis covers several studies conducted in two projects. LÄS MER

  4. 8. A Position Control-based Approach to Stiff Objects Haptic Rendering

    Författare :Yang Wang; Kjell Andersson; Lei Feng; Anders Robertsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; haptic rendering; position control-based approach; rigid-body interaction; Machine Design; Maskinkonstruktion;

    Sammanfattning : With electronic components and computational power becoming more portable and available to general consumers, applications like virtual reality (VR) and mixed reality (MR) are on the rise and renovating the industry of training simulators. Though it is not fully accepted in surgical robots, haptic force feedback can be safely introduced into various surgical training simulators to convey the necessary haptic cues needed to develop hand-eye coordination and motor skills.

  5. 9. Haptic Interaction with Deformable Objects

    Författare :Umut Kocak; Matthew Cooper; Karljohan Lundin Palmerius; Miguel Otaduy; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The integration of haptics into virtual environments has triggered a new era by allowing interaction with virtual objects through force feedback in a number of fields. Medicine has been the field with highest potential benefit through improved realism and immersion. LÄS MER

  7. 10. Surgical Education Assessment of simulators for training and selection of trainees

    Författare :Kristine Hagelsteen; Lund Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Laparoscopy; Simulation; 3D; Haptic feedback; Personnel Selection; Surgical training; interview methods; Professionalism; Professional competence; Remediation; Residency; Human factors; warning signs;

    Sammanfattning : BackgroundApproximately 15 % of surgical patients in hospital are affected of an adverse event, which is a medical error caused by the health care system. Laparoscopy is the preferred surgical technique in common procedures. LÄS MER
