This study explored touchscreen keyboards using high precision touchscreen strategies. Phase one evaluated three possible monitor positions: 30, 45, and 75 degrees from horizontal. Results indicate that the 75 degree angle, approximately the standard monitor position, resulted in more fatigue and lower preference ratings. Phase two collected touch bias and key size data for the 30 degree angle....

We present an electrostatic tactile display for stimulus localization. The 240-Hz electrostatic force was generated by the beat phenomenon in a region where excited X electrodes cross excited Y electrodes, which presents localized tactile sensation out of the entire surface. A 10.4in. visual-tactile integrated display was successfully demonstrated. key words: tactile display, electrostatic forc...

used in conjunction with or as a replacement for traditional methods, it is expected that specific laser technologies will become an essential component of contemporary dental practice over the next decade. the current review is designed to focus on the acid resistance of laser application and tries to introduce laser settings capable to achieve this feature for clinical application. applicatio...

This research is to use fuzzy controller to eliminate hysteresis effect of a force actuator for a Scanning Probe Microscope (SPM). This improvement has been verified by MATLAB simulation and practical implementation to reduce the hysteresis effect of the force actuator. Comparisons with two previous designs with and without Linear Velocity Transducer (LVT) for inner-loop feedback compensation a...

statement of problem: it has been established that successful root canal treatment depends on the quality of obturation. deeper penetration of spreaders can improve the apical seal and the quality of the obturation. purpose: the aim of this study was to compare the initial penetration depth of spreaders during lateral condensation of 0.04 and 0.02 tapered gutta-percha master cones. materials an...

Virtual reality technology brings numerous advantages to many different application fields and the continuous increase in computational power and network speed means that it is possible to find new methods to improve training and reduce education costs. It is becoming feasible to realize multi-user systems via networks and interactive applications with world wide accessibility features and coll...

This paper presents a new design of a harness for torso force application in locomotion interfaces. This mechanical coupling between a user’s body and the force feedback device is a key aspect for the effective exploitation of this class of devices. Issues of compliance, backlash, force distribution, and comfort have been considered in the new design. Experimental results show that subjects adj...

abstract:the paper begins by noting that proposals involving significant developments in the regional tradearchitecture are being developed within regional processes that in some cases are simultaneouslypursuing other dimensions of regional economic integration: monetary and financial cooperation inthe case of asean + 3, and the establishment of a common market in the case of asean. at leastthr...
