a projecting arrangement configured to project graphics onto a bowling lane; and a processing unit configured to send, from the data storing device to the projecting arrangement, oil pattern data corresponding to one oil pattern of said set of oil patterns, whereby graphics representing the one oil pattern of said set of oil patterns is projected onto the bowling lane. ## Claims ### Claim 1 A system for facilitating practice of bowling, wherein the system comprises: a data storing device configured to store oil pattern data corresponding to a set of oil patterns for bowling lanes; a projecting arrangement configured to project graphics onto a bowling lane; and a processing unit configured to send, from the data storing device to the projecting arrangement, oil pattern data corresponding to one oil pattern of said set of oil patterns, whereby graphics representing the one oil pattern of said set of oil patterns is projected onto the bowling lane. ### Claim 2 (depends on 1) The system according to claim 1, further comprising: a tracking arrangement configured track movement of a bowling ball on the bowling lane and to generate tracking data corresponding to a bowling ball trajectory; wherein the processing unit is further configured to compare the tracking data to the oil pattern data and to update the oil pattern data in the data storing device based on the comparison, the updated oil pattern data corresponding to an adjusted oil pattern; and wherein the processing unit is configured to send, from the data storing device to the projecting arrangement, the updated oil pattern data, whereby graphics representing the adjusted oil pattern is projected onto the bowling lane. ### Claim 3 A system for facilitating practice of bowling, wherein the system comprises: a data storing device configured to store intended trajectory data corresponding to an intended bowling ball trajectory; a projecting arrangement configured to project graphics onto a bowling lane; and a processing unit configured to send, from the data storing device to the projecting arrangement, intended trajectory data corresponding to at least part of the intended bowling ball trajectory, whereby graphics representing at least part of the intended bowling ball trajectory is projected onto the bowling lane. ### Claim 4 (depends on 3) The system according to claim 3, further comprising: a tracking arrangement configured track movement of a bowling ball on the bowling lane and to generate tracking data corresponding to a bowling ball trajectory. ### Claim 5 (depends on 4) The system according to claim 4, wherein the processing unit is further configured to compare the intended trajectory data to the tracking data and to, based on the comparison, generate accuracy data; and wherein the system further comprises: an interface configured to present the generated accuracy data. ### Claim 6 (depends on 5) The system according to claim 5, wherein the accuracy data represents a deviation in the bowling ball trajectory to the intended bowling ball trajectory. ### Claim 7 (depends on 4) The system according to claim 4, wherein the processing unit is further configured to send, from the tracking arrangement to the projecting arrangement, tracking data corresponding to at least part of the bowling ball trajectory, whereby graphics representing at least part of the bowling ball trajectory is projected onto the bowling lane simultaneously with the graphics representing at least part of the intended bowling ball trajectory. ### Claim 8 (depends on 3) The system according to claim 3, further comprising: a graphical user interface configured to receive, by a user, input data defining the intended bowling ball trajectory; wherein the data storing device is further configured to store the input data defining the intended bowling ball trajectory as intended trajectory data. ### Claim 9 (depends on 8) The system according to claim 8, wherein the processing unit is further configured to send, from the tracking arrangement to the graphical user interface, tracking data corresponding to at least part of the bowling ball trajectory and, from the data storing device to the graphical user interface, intended trajectory data corresponding to at least part of the intended bowling ball trajectory, whereby graphics representing at least part of the bowling ball trajectory and graphics representing at least part of the intended bowling ball trajectory are displayed on the graphical user interface. ### Claim 10 (depends on 4) The system according to claim 4, wherein the processing unit is further configured to send, from the tracking arrangement to a display, tracking data corresponding to at least part of the bowling ball trajectory and, from the data storing device to the display, intended trajectory data corresponding to at least part of the intended bowling ball trajectory, whereby graphics representing at least part of the bowling ball trajectory and graphics representing at least part of the intended bowling ball trajectory are displayed on the display. ### Claim 11 (depends on 3) The system according to claim 3, wherein the intended trajectory data corresponding to an intended bowling ball trajectory comprises a breakpoint of the bowling ball when moving on the bowling lane.
