20090061972 | SPEED-DEPENDENT SUGGESTED DRIVING LINES - In a video game or simulator, suggested speed indicators are computed along a suggested driving line on a path (e.g., a race track) and displayed in a simple, progressive, and user-friendly format. The displayed speed indicators are based on a racer's current speed and target speeds attributed to individual locations along the suggested driving line on the path. The speed indicators provide a dynamic indication of where and how the player should slow down or speed up relative to their current speed as their racer travels along the path. The speed indicators are displayed (e.g., using color to represent different magnitudes of suggested acceleration and deceleration) along the suggested driving line in front of the racer so that the player can anticipate braking and acceleration actions as the path and the racer's speed change. | 03-05-2009 |

20090051690 | Motion line switching in a virtual environment - A computing system enhances the human-like realism of computer opponents in racing-type games and other motion-related games. The computing system observes multiple prescribed motion lines and computes switching probabilities attributed to switching of simulated motion of a racer from one prescribed motion line to another. A sampling module samples at random over the switching probabilities to select one of the switching probabilities. At least one control signal is generated to switch simulated motion of the entity in a virtual reality environment from the first prescribed motion line to one of the other prescribed motion lines, in accordance with the selected one of the switching probabilities. | 02-26-2009 |
20100240430 | COMPUTING A TARGET SPEED IN A VIRTUAL RACING ENVIRONMENT - A target speed profile for a specified racer is computed at various points along a track. The calculation is based on the real world physics of the racing environment and incorporates physical characteristics of the track, including curvature, undulation, and/or camber. A lateral acceleration component is developed to limit the realistic maximum speed a racer may obtain at any given point along the track. Furthermore, differences in realistic maximum speeds at different points along the track can overwhelm a racer's braking capability. As such, braking capacity adjustments can be applied to decrease the maximum speed in the target speed profile, so that the overall target speed profile is more realistic and attainable. | 09-23-2010 |
20110137629 | RACING LINE OPTIMIZATION - An automatic algorithm for finding racing lines via computerized minimization of a measure of the curvature of a racing line is derived. Maximum sustainable speed of a car on a track is shown to be inversely proportional to the curvature of the line it is attempting to follow. Low curvature allows for higher speed given that a car has some maximum lateral traction when cornering. The racing line can also be constrained, or “pinned,” at arbitrary points on the track. Pinning may be performed randomly, deterministically, or manually and allows, for example, a line designer to pin the line at any chosen points on the track, such that when the automatic algorithm is run, it will produce the smoothest line that still passes through all the specified pins. | 06-09-2011 |
