Bi-directional remote controller and data broadcasting guidance system and method using the same

Abstract: Disclosed is a data broadcasting guidance system and method which guides a user and enhances the availability of the data broadcasting. The data broadcasting guidance system includes means for extracting guidance information while a data broadcasting is displayed; means for requesting a guidance on the data broadcasting; and means for notifying the extracted guidance information in response to the request from the requesting means. Accordingly, the guidance information to navigate the data broadcasting is supplied and the remote controller is controlled more exactly and faster so that the user's attention is drawn to the data broadcasting and the broadcast gets popular.

Simulation study of driving performance with selected route guidance systems

Abstract: Experiments were conducted in a driving simulator developed by the Hughes Aircraft Corporation to study the human factors aspects of route guidance systems. The primary objective of this research was to study how in-vehicle route guidance system attributes, driver characteristics, and traffic conditions affect driving performance. Four types of route guidance systems were tested. They are: (1) Paper Map, (2) Heads Down Electronic Map, (3) Heads Up Display (HUD) in combination with Electronic Map, and (4) Voice Guidance in combination with Electronic Map. Data were collected for a total of 18 subjects, 9 male and 9 female. All subjects were tested in all four route guidance systems. The following performance measures were collected in the simulator: Number of Navigation Errors and Reaction times to external events. Apart from these, an unobstrusive eye tracker was also used to monitor eye fixations. Data were also collected on driver preferences and subjective workload associated with each of the four route guidance systems. The results of the study can be summarized as follows: (a) Subjective workload, user perceptions, eye tracker dwelling times, and number of errors all indicated that the voice guidance/electronic map combination performed the best, and the paper map the worst. The electronic map was found to be the second best, closely followed by the HUD electronic map. (b) The reaction time modelling yielded slightly different device performance depending on the event being reacted to. The heads up display/electronic map combination performed much better in comparison to its performance in the other performance measures, with voice/electronic map also doing well. The paper map again consistently performed the worst. (c) Driving performance did vary with gender and experience. Not surprisingly, drivers with higher experience performed better than drivers with lower experience. This effect was more prominent among females than males.

Line of sight missile guidance

Abstract: In known guidance systems, the missile is guided by a control loop which includes the missile and a ground-based tracker, the tracker determining the relative positions of the missile and target and hence the lateral acceleration to be applied to the missile. However, these systems do not take account of the lateral acceleration generated by the coupling of the missile acceleration along its longitudinal axis and the angle between the body of the missile and the sightline, as in cases where acceleration is small the effect is insignificant. Described herein is a system for modifying the demand component to effect compensation for the lateral acceleration component imparted to the missile by virtue of its angle of incidence. This is accomplished by modifying the demand component in accordance with a stored predetermined time-varying gain term thereby to effect compensation of the lateral acceleration component imparted to the missile by virtue of the angle of incidence of the missile.

View navigation guidance system for hand held devices with display

Abstract: System and method for view navigation guidance system for a physical display that is smaller than the virtual display it needs to display. Guidance map placed in a heads-up display layer within a small user defined area of the physical display provides an instantaneous indication of the current position of the screen view with minimal obstruction of the contents information. Color selection for the guidance map is automatically determined based on the background color in the main display layer beneath the map. The guidance map area on a touch screen display may include tapping controls, and the position of the guidance map can be dynamically altered by the user during the view navigation to control the navigation parameters.
