Our specific application is seated posture guidance. Poor sitting postures, over time, can lead to health concerns such as low back pain. We propose a real-time haptic feedback system that actively senses and guides a person to a desired posture. We have instrumented an ergonomic office chair with a simple system using 7 force-sensitive resistors (FSRs) for posture detection and 6 vibrotactile actuators (“tactors”) for haptic feedback. When the chair detects that the subject is not sitting in the desired posture, one or more tactors will vibrate, directing the subject towards or away from a certain position. In a pilot study of 10 subjects (age 23.9±1.45, weight 71.1±13.6kg, height 175±11.2cm), 100% sat in the reference posture (upright) more often when there was haptic feedback than when there was not. Additionally, when haptic feedback was temporarily disabled without the subject's knowledge, all of the subjects continued to sit in upright or near-upright postures. These findings suggest that vibrotactile feedback can be an effective means of communicating musculoskeletal commands to the human sensory-motor system, especially for motor training and rehabilitation.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"36 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":"127579164","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}

To determine the specifications of an actuator for a tactile display enhanced by VHI, we investigate the relationship between wire distance and intensity of illusionary sensation using a series of psychophysical experiments. According to the experimental results, the strength of VHI depends on the distance between two adjacent wires and saturates at around 55 mm. In VHI, although the area bounded by two wires moves relative to the hands, tangential force does not occur on either hand, causing operators to experience the illusion of touching a smooth virtual film with a zero coefficient of friction. Since the strength of VHI becomes small for a small distance between two adjacent wires, excessive tangential stimulation prevents the occurrence of VHI. Therefore, VHI control requires two actuations: one is for normal actuation on the operator's finger surface to generate a touch feeling; the other is appropriate tangential actuation to generate a moving-edge feeling on the operator's finger surface.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"43 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":"121675589","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}

Studies were conducted with 10 naive subjects first to characterize the nonlinear stiffness of the skin with respect to applied rotations and subsequently to characterize the skin viscoelastic response and hysteresis. Despite substantial subject-to-subject variability, when results are normalized by each subject's maximum torque, the torque/displacement results are fairly consistent across subjects, at low and high speeds, and can be fit with a third order polynomial. For roughly one half of the subjects, a similar nonlinearity is discernible in the perceived versus actual rotation; other subjects produced nearly linear results across the range of positive and negative rotations. Viscoelastic and hysteresis effects in the skin were also evident. However, while subjects can clearly distinguish between slow and rapid movements, the speed of the applied motion does not significantly affect their perception of rotation.","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":"115972922","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 grazing on the inner walls of the airway, if not well controlled, could lead to unnecessary trauma for the patient. Hence, there is a need to provide this force feedback in a fiber-optic intubation simulator. We have built a force feedback device that incorporates both the force feedback when contact is made with the vocal-cord section as well as grazing of the endoscope along the inner walls of the airway. We use a PD controller to obtain force feedback at the vocal-cord section and a variable magnetic field to replicate the frictional force feedback caused by the grazing of the endoscope along the inner walls of the airway. The movements of the endoscope are captured using rotary encoders (which read the insertion and the tip bend) and a magnetometer (which reads the twist angle of the endoscope along the long axis). We performed tests based on the intensity of contact of the endoscope against the vocal-cords and the inner walls of the airway. Changes in the intensity of grazing at the inner walls of the airway were observed by actively varying the coil current in the magnet. The simulator will help to train all aspects of fiber-optic intubation which involves contact with the vocal-cords as well as grazing the surface of the airway.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"21 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":"123751216","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}

Subjects used the UW Multi-Finger Haptic Display to interact with small haptic icons in a virtual environment. A forced-choice adaptive thresholding method is used to find a minimum detectable force magnitude. First, studies are performed to evaluate the consistency of our test apparatus across the four fingertips and to compare our application of the adaptive thresholding method to the prior work. Next, force detection thresholds for individual fingers are collected and compared to the force detection threshold using four fingers simultaneously. The results show comparable force detection levels between index, middle, pinkie and multi-finger interaction (33.5, 32.1, 33.5, 28.9 mN respectively) but less sensitivity with the ring finger (mean threshold of 43.6 mN). Repeated measures analysis of variance and t-tests with Bonferroni correction supports these conclusions. Most importantly, we show that the multi-finger threshold is not significantly lower than the threshold of the individual fingers. The implication for device design is that the relevant multi-finger device parameters are no more stringent than for single finger devices.","PeriodicalId":239293,"journal":{"name":"2010 IEEE Haptics Symposium","volume":"30 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":"114496441","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}
