Sergey Kulikov, I. Scott MacKenzie, Wolfgang Stuerzlinger. Penal Code § 69 (resisting / dissuading pubic officer by threatening or using violence) is the latest tool in the government's defensive arsenal to prevent you from obtaining justice and redress for government outrages perpetrated against you. b : the discriminatory … The vertical tunnel needs to be short, but that means that each of the items in the menu may have to be given smaller height — which leads to narrow horizontal tunnels. Menus are one of the UI elements most affected by the Steering Law. The steering control must have a minimum collapsing space of 100 mm between the steering control and the test bench. The steering law is one of several laws of action that have to do with the process of human-computer interaction. To access this resource, sign up for a free trial of Practical Law. (iv) Each rudder angle indicator in relation to the actual position of the rudder. Therefore, for precise tasks, supplement these UI elements with other secondary controls that support precision. Individual results may vary as outcomes are determined on a case by case basis. The Accot-Zhai Steering Law (discovered by HCI researchers Johnny Accot and Shumin Zhai, but also known simply as the Steering Law) is a corollary of Fitts’s Law. (2017) Global Singularity Avoidance Steering Law for Single-Gimbal Control Moment Gyroscopes. The response of attitude quaternion is presented in Fig. The Parties shall establish a joint committee (the "STEERING COMMITTEE"), which shall oversee the research, development and commercialization activities hereunder.Each of Northwest and Medarex: shall appoint an equal number of representatives with the requisite experience and seniority to enable them to make decisions on behalf of the Parties with … You are currently offline. Here are a few design choices to make them easy to use. The steering law keeps acceleration value below maximum limit in the de-spin cycles. Hierarchical menus are inherently a difficult UI to design well due to Steering Law constraints. Lexie Kane: You must have javascript and cookies enabled in order to display videos. Steering gear mechanism The steering mechanism is used in automobiles for changing the directions of the wheel axles with reference to the chassis, so as to move the automobile in the desired path. For navigation menus, consider mega menus (or square menus) as an alternative to pull-down menus. a : the practice of pushing or deceiving loan applicants into applying for more costly loans. Subscribe to our Alertbox E-Mail Newsletter: The latest articles about interface usability, website design, and UX research from the Nielsen Norman Group. The Accot-Zhai Steering Law (discovered by HCI researchers Johnny Accot and Shumin Zhai, but also known simply as the Steering Law) is a corollary of Fitts’s Law. The padding will allow some wiggle room for the user to move along the tunnel without dropping out because of a small deviation outside the tunnel’s visual area. There is no law specifically related to steering wheel size. Basic Law Promotion Steering Committee - index.html Introduction Over the years, the Government has been promoting the Basic Law through civic education, school education and training for civil servants. On April 21, Sébastien Fleury, a Steering Legal partner, answers questions asked by landlords and tenants in the midst of a period of confinement in L'Usine nouvelle. We’ve been serving clients for more than a century, and we’ve been climbing the ranks of the nation’s largest firms for many years, according to both The Am Law 100 and The National Law Journal. Overstepping the border will have some consequence, though since this is a common user error, the consequences will hopefully be mild, such as having the computer stop paying attention while the pointer is outside the tunnel. Although it is a single axis maneuver, but small motion is observed on other two axes of satellite. The Steering Law states that narrow, long tunnels are more difficult to navigate than short, wide ones. The steering law in human–computer interaction and ergonomics is a predictive model of human movement that describes the time required to navigate, or steer, through a 2-dimensional tunnel.The tunnel can be thought of as a path or trajectory on a plane that has an associated thickness or width, where the width can vary along the tunnel. Some of the most common UI elements that involve this type of interaction include dropdown menus (particularly hierarchical menus with hover-revealed submenus), parameter-control sliders, scroll bars, video-playback scrubber bars, and video-game elements that require drag and drop in a straight line. Natural Mappings and Stimulus-Response Compatibility in User Interface Design, How to Report Errors in Forms: 10 Design Guidelines, User Interface Principles Every Designer Must Know. Summary: Dropdowns, hierarchical menus, sliders, or scroll bars involve steering a pointer or a cursor through a tunnel; optimal design for these GUI elements should consider the Steering Law.

Following the consolidation of Fiji's laws in 2016, the Fijian Government is proud to launch the first-ever online platform of Fiji's consolidated laws, providing a one-stop shop for anyone seeking to access the laws of the Republic of Fiji. Why people have trouble maintaining the cursor on a straight path has to do with human physiology: the elbow and wrist, which enable the movement of the hand, describe an arc, not a line. Finally, you can add padding to a tunnel, making its effective width bigger than its visual representation on the screen. Free Practical Law trial. : the act of directing another to pursue a course of action: as. This process of pushing buyers one direction or another based on any protected class is known as "steering," and it is strictly prohibited. Also, allow users to click anywhere on the slider to jump to the desired position, rather than requiring them to click and drag; this approach enables a user to move freely in 2D space without needing to steer through the tunnel. There will always be a tradeoff between designing the two tunnels associated with a hierarchical menu: the vertical tunnel that corresponds to the main-menu area and the horizontal tunnel, that corresponds to subcategory name that the user has to traverse to open the submenu: When a hierarchical menu is absolutely necessary, use a short time delay between mouse hover and when reveal of the child menu (or use a vector-based triangular system to allow for some diagonal movement error). Anti-steering laws have been the subject of class action lawsuits in several states alleging millions of dollars in damages and statutory fines.

Abstract An attitude tracking controller is developed for control moment gyroscope (CMG)-actuated satellites, which is shown to…, We present a satellite path-planning technique able to make a set of identical spacecraft acquire a given configuration. Dropdown menus, hierarchical menus, sliders, and other path-following UI elements should be designed so that the corresponding tunnel is as wide and as short as possible. Formation of Steering Committee.
