Close Range

The problem of teleoperating a mobile robot using shared autonomy is addressed: An onboard controller performs close-range obstacle avoidance while the operator uses the manipulandum of a haptic probe to designate the desired speed and rate of turn. Sensors on the robot are used to measure obstacle-range information. A strategy to convert such range information into forces is described, which are reflected to the operator's hand via the haptic probe. This haptic information provides feedback to the operator in addition to imagery from a front-facing camera mounted on the mobile robot. Extensive experiments with a user population both in virtual and in real environments show that this added haptic feedback significantly improves operator performance, as well as presence, in several ways (reduced collisions, increased minimum distance between the robot and obstacles, etc.) without a significant increase in navigation time.

Abstract Purpose Cooperative surgical systems enable humans and machines to combine their individual strengths and collaborate to improve the surgical outcome. Cooperative telemanipulated systems offer the widest spectrum of cooperative functionalities, because motion scaling is possible. Haptic guidance can be used to assist surgeons and haptic feedback makes acting forces at the slave side transparent to the operator, however, overlapping and masking of forces needs to be avoided. This study evaluates the usability of a cooperative surgical telemanipulator in a laboratory setting. Methods Three experiments were designed and conducted for characteristic surgical task scenarios derived from field studies in orthopedics and neurosurgery to address bone tissue differentiation, guided milling and depth sensitive milling. Interaction modes were designed to ensure that no overlapping or masking of haptic guidance and haptic feedback occurs when allocating information to the haptic channel. Twenty participants were recruited to compare teleoperated modes, direct manual execution and an exemplary automated milling with respect to usability. Results Participants were able to differentiate compact and cancellous bone, both directly manually and teleoperatively. Both telemanipulated modes increased effectiveness measured by the mean absolute depth and contour error for guided and depth sensitive millings. Efficiency is decreased if solely a boundary constraint is used in hard material, while a trajectory guidance and manual milling perform similarly. With respect to subjective user satisfaction trajectory guidance is rated best for guided millings followed by boundary constraints and the direct manual interaction. Haptic feedback only improved subjective user satisfaction. Conclusion A cooperative surgical telemanipulator can improve effectiveness and efficiency close to an automated execution and enhance user satisfaction compared to direct manual interaction. At the same time, the surgeon remains part of the control loop and is able to adjust the surgical plan according to the intraoperative situation and his/her expertise at any time.

Top Management Support

The use of Accounting Information System (AIS) is very helpful in accommodating all the information needed to make an accurate decision. Indicators in determining the good and bad performance of an information system can be seen through AIS user satisfaction and usage. The purpose of this study was to determine the effect of top management support, system quality and information quality on AIS user satisfaction. The sample selection method used was purposive sampling. The research sample was 147 people consisting of administrators, loan officers and savings at 29 Lembaga Perkreditan Desa (LPD) in Ubud Subdistrict. The data in this study is primary data which is the answer from the questionnaire. The regression results show that all variables have a significance of 0,000. It shows that top management support, system quality and information quality have positive influences on Accounting Information System user satisfaction.

The Influence of Location and Facilities Against Satisfaction of Container Unloading Service User at PT Pelabuhan Indonesia IV (Persero) Merauke Branch.This study aims to determine how much influence the location and facilities to the satisfaction of service users. Locations have indicators: access, visibility, traffic and facilities have indicators: organizational characteristics and objectives, land availability and space and space requirements, flexibility, aesthetic factors, communities and the environment, construction and operation costs while service user satisfaction has indicators: customer satisfaction , dimensions of customer satisfaction, confirmation of expectations, repurchase interest, willingness to recommend, customer dissatisfaction.The method used in this research is quantitative method by using the technique of processing descriptive data, data collecting technique with interviews, questionnaires and literature study. Sampling technique used incidental sampling. The measurement using likert scale and processed using SPSS version 23 program to calculate the validity and reliability test, calculate hypothesis test that is t test, f test and coefficient of determination. The result of research shows that location and facility variables together have a positive influence on service user satisfaction at PT Pelabuhan Indonesia IV (Persero) Merauke Branch. This can be proven from the result of F count 39.984> 3.11 with significance level 0.000 ≤ 0.05, then Ho is rejected Ha accepted. Itcan be concluded there is a positive and significant relationship between location and facility to the satisfaction of service users of loading and unloading of containers at PT Pelabuhan Indonesia IV (Persero) Merauke Branch.The result of research shows that location and facility variables together have a positive influence on service user satisfaction at PT Pelabuhan Indonesia IV (Persero) Merauke Branch.
