[0002] The present invention relates to sporting events generally and to management of sports matches in particular.

[0003] Traditionally, a sports referee may use several tools to manage a sports match. For example, in a football (soccer) match, the tools may include a coin to toss deciding the team initially in possession of the ball, red and yellow cards to indicate penalties and warnings, and watches to keep track of the game time and the accumulation of injury time. During the football match the referee may also use a writing instrument and paper to record information such as yellow/red card warnings issued, scored goals by each team and time of score, the identity of a goal scorer, player substitutions, distances on the playing field, and other information. After the football match, the referee has generally manually compiled information about the match so it may be recorded in a report, for example, by national and/or international league officials and/or organizations. Such a compilation process may be time consuming, and may include inaccuracies as the referee attempts to reconstruct the events of the match after the fact.

[0004] In addition to the sports referees, many observers of sports matches, for example, journalists, broadcasters, and spectators, often independently record their own observations during a sports match, and then may afterward reconcile their observations with the official record.

This data may include recorded input data acquired through the match, including images, verbal inputs by the referee and refereeing personnel, including conversations.

[0082] Reference is now also made to FIG. 5 which schematically illustrates implementation of FB-RS 100 for refereeing a football match and as part of a larger match monitoring system 10, according to an embodiment of the present invention. The football match is played in a football field 180 and includes as refereeing personnel a referee 182, an assistant referee 184, a first lineman 186, and a second lineman 188. Each of the refereeing personnel is equipped with a FB-RS 100 which includes glasses 102 and a FB-RS 150 Referee 182 may be additionally equipped with a warning display screen 160. Additionally or alternatively, the warning display screen may be implemented in FB-MM 150 of referee 182.

[0083] FB-RS 100 of referee 182, assistant referee 184, first lineman 186 and second lineman 188 are interconnected through communications network 140 and may allow the refereeing personnel to verbally communicate with one another, and to share images captured real-time, during the game. For example, referee 182 may communicate with lineman 186/188 to discuss a call by the lineman, or may view through his (the referee's) glasses images acquired by the lineman during the play. Referee 182 may view the images on his glasses in replay-format, or alternatively, the referee may switch channels in his glasses, or through his FB-MM 150, to switch into real-time vision as seen by first lineman 186a or any other refereeing personnel through their glasses. The plurality of FB-MM 150 may be interconnected to allow the referee, or possibly the other refereeing personnel, to access information which may be captured real-time, or stored, in the FB-RS 100 of the other refereeing personnel.

[0084] Larger match monitoring system 10 may allow match data to be shared with match followers 190 over communications network 140. Match followers 190 may be present in the football stadium during the match, or may be remotely located anywhere in the world, and may be equipped with computing devices 152, for example personal computers, laptop computers, tablet computers, and mobile phones, including a downloaded dedicated application program which allows receiving match data from referee 182 FB-RS 100. Additionally, computing devices 152 may receive match data from other refereeing personnel FB-RS 100. Additionally or alternatively, the match data may be received from data server 170. Additionally or alternatively, match followers 190 may wear a modified version of smart glasses 102 which allows them to receive shared data directly to a receiver on the glasses over communications network 140. This modified version of smart glasses 102 may be potentially advantageous as it may be of a reduced cost for mass merchandising purposes, the reduced cost of the glasses achievable by providing only data reception and display functions on the glasses. The modified version of smart glasses 102 may include commercially available smart glasses known in the art and suitable for displaying the shared match data. An application program may be downloadable to the commercially available smart glasses to allow displaying the shared match data on the glasses. Also downloadable and displayable may be advertising contents and/or other data contents not limited to the shared match data. The match data received may include the match report, and may be received on a real-time basis during match progress. Alternatively, the match data may be received not real-time, and may include receiving the data only after the match has finalized. The match data received may be selective data and may vary according to a type of match follower 190. For example, journalists, broadcasters, and sports writers may receive match data which may include details not provided to spectators.

[0085] Reference is now made to FIG. 6 which schematically illustrates an exemplary data display screen 207 in linesman smart glasses 202, according to an embodiment of the present invention. Linesman smart glasses 202 may be functionally similar to smart glasses 102 modified to allow a soccer game linesman to monitor and determine when an offensive game player is in an “offside” situation.

[0086] Data display screen 207 may be included in display 106 and may include a plurality of thin vertical lines 203 which may be used by the linesman to identify the position of players relative to one another. Lines 203 may be equally spaced and may represent a whole length of the playing field, or a section of the playing field. Lines 203 may allow glass 202 automatic detection of “offside” conditions where one or more offensive game players may be positioned in the playing field between a last defensive player and the goalkeeper. Additionally or alternatively, the detection may be visually performed by the linesman. Smart glasses 202 may be configured to emit a warning signal to the linesman of a detected offside condition and correspondingly an “offside” violation. The warning signal may be a visual signal displayed on data display screen 207. Additionally or alternatively, the warning signal may be an audio signal emitted through sound transducer 111. Glasses 202 may allow identification of the offensive play that has committed an offside violation, and may allow zooming into the playing area of the offensive player. Additionally, glasses 202 may allow automatic transmission of details associated with the offside violation to glasses 102 worn by the referee.

[0087] Unless specifically stated otherwise, as apparent from the preceding discussions, it is appreciated that, throughout the specification, discussions utilizing terms such as “processing,” “computing,” “calculating,” “determining,” or the like, refer to the action and/or processes of a computer, computing system, or similar electronic computing device that manipulates and/or transforms data represented as physical, such as electronic, quantities within the computing system's registers and/or memories into other data similarly represented as physical quantities within the computing system's memories, registers or other such information storage, transmission or display devices.

[0088] Embodiments of the present invention may include apparatus for performing the operations herein.
