This haptic system consists of some recently developed MRI-compatible mechatronic devices, including a fiber optic force sensor and a piezoelectric motor actuated needle driver mounted on a specifically designed 3-axis linear stage. We first propose the teleoperation framework with system architecture, infrastructure and control algorithm for the master-slave haptic interface. Then we introduce some novel sensors and actuators for MRI-compatible mechatronic devices of this haptic system. We developed the force sensor which provides in-vivo measurement of needle insertion forces to render proprioception associated with the brachytherapy procedure. We discuss the sensing principle of the optical sensor which enables two degrees-of-freedom (DOF) torque measurement and one DOF force measurement. The second apparatus of this system is a high precision 3-axis linear stage actuated by piezoelectric motors and position sensed by optical linear and rotary encoders and all of them have proved good magnetic compatibility. The needle driver can simultaneously provide needle cannula rotation and stylet translation motion while the cannula translation is engendered by the stage. The independent rotation and translation motion of the cannula and stylet can increase the targeting accuracy while minimize the tissue deformation and damage. The master-slave haptic system is capable of positioning needle and sensing insertion forces thus increasing the operation autonomy, accuracy and reducing the operation time.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115268094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple force cues are typically summed to produce a single output force, which conveys only relative information about the original force cues and may not be useful to trainees. Two force co-presentation paradigms are proposed as potential solutions to this problem: temporal separation of force cues, where one type of force is overlaid with the other in staggered pulses, and spatial separation, where the forces are presented via multiple haptic devices. A generalized model for separating task and guidance forces in a virtual environment is also proposed. In a pilot study where sixteen participants were trained in a dynamic target-hitting task using these co-presentation paradigms, simple summation was in fact most effective at eliciting skill transfer in most respects. Spatial separation imposed the lowest overall workload on participants, however, and might thus be more appropriate than summation in tasks with other significant physical or mental demands. Temporal separation was relatively inferior at eliciting skill transfer, but it is hypothesized that this paradigm would have performed considerably better in a non-rhythmic task, and the need for further research is indicated.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121038509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The tactile stimuli consisted of six raised cosine pulses at two levels of frequency and three levels of amplitude. An absolute identification experiment was conducted to measure the information transfers associated with the tactile-audio signal set. Results from Condition 1 (C1) provided a baseline measure by employing only the tactile signals. In Conditions 2–4 (C2–C4), supplemental audio signals were used to encode amplitude cues only, frequency cues only, and both amplitude and frequency cues, respectively. The results showed that partial redundant coding of tactile cues with audio signals could increase information transfer, when the cue (amplitude) was not perfectly identifiable with tactile signals alone (C2). When the cue (frequency) was well perceived through tactile signals alone, audio supplemental cues did not improve performance (C3). With redundant coding of both amplitude and frequency cues (C4), audio signals dominated tactile signals. It was also found that increased information transfer was achieved at the cost of increased response time (C2), suggesting increased mental load associated with the processing of multisensory information. Our findings have implications for the design of simulated key-click signals for mobile devices, and the use of multimodal signals for redundant coding of information in general.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129522583","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we want to show that the haptic modality can equally well recover the underlying structure of a physical object space, forming a perceptual space that is highly congruent to the visual perceptual space. By varying three shape parameters a physical shape space of shell-like objects was generated. Sighted participants explored pictures of the objects while blindfolded participants haptically explored 3D printouts of the objects. Similarity ratings were performed and analyzed using multidimensional scaling (MDS) techniques. Visual and haptic similarity ratings highly correlated and resulted in very similar visual and haptic MDS maps. To investigate to which degree these results are transferrable to natural objects, we performed the same visual and haptic similarity ratings and multidimensional scaling analyses using a set of natural sea shells. Again, we found very similar perceptual spaces in the haptic and visual domain. Our results suggest that the haptic modality is capable of surprisingly acute processing of complex shape.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128291119","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The idea is based on well-known tactile illusions of apparent tactile motion and “phantom” sensation. The phantom sensation refers to a perceptual phenomenon where spatially separated vibrotactile actuators that stimulate different skin zones induce a single tactile sensation midway between the two stimulation points. We tested whether such sensation can also be elicited in a mobile device via a psychophysical experiment that employed an open response paradigm. Experimental conditions differed in vibration rendering method, signal duration, and sensation movement direction. The subjects answered the perceived positions and intensities of vibrotactile sensations by drawing graphs with respect to time. The results demonstrated that such “vibrotactile flow” can be reliably produced in a mobile device and that a performance trade-off exists depending on the method and signal duration used for rendering. The findings of this paper can be applied to the user interface design of a mobile device with enriched vibrotactile sensations and an improved information transfer bandwidth.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125891961","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
