The system is composed of sensors that provide both directional and velocity information related to objects within the device/wearers surroundings. A computer device receives this information and translates it into a collision path and notifies the wearer of a possible collision and its trajectory. ## Claims ### Claim 1 A user wearable system, comprising: one or more object tracking sensors; one or more force sensors; a computer readable memory comprising processor executable modules; and a processor, coupled to the computer readable memory, that executes or facilitates execution of the processor executable modules, the processor executable modules comprising: a trajectory module that processes data received from the object tracking sensors to calculate a trajectory of an object within a spatial vicinity of a user; a force module that calculates a force applied to the user wearable system from data received from force sensors; and an alert module that receives a calculated object trajectory signal from the trajectory module and a calculated applied force signal from the force module and determines if an alert should be provided to the user regarding the force from a collision and the trajectory of an object likely to collide with the user. ### Claim 2 (depends on 1) The system of claim 1, wherein the user wearable system is a projective helmet. ### Claim 3 (depends on 1) The system of claim 1, wherein the calculated applied force is uploaded to a remote communication device to alert a different user when the calculated applied force exceeds a selected threshold. ### Claim 4 (depends on 3) The system of claim 3, wherein details of an associated event including a username, date, and time are uploaded in association with the calculated applied force to the remote communication device. ### Claim 5 (depends on 1) The system of claim 1, wherein the alert is one or more of visual, audible, and tactile. ### Claim 6 A user wearable device, comprising: one or more trajectory sensors to track paths of objects relative to the user wearable device; one or more force sensors to measure gravitational loads applied to the user wearable device; a user interface to notify a user of an impending collision with an object and a direction of travel of the object; and a network interface to notify a remote communication component that an excessive force has been applied to the user. ### Claim 7 (depends on 6) The device of claim 6, wherein the user wearable device is a projective helmet. ### Claim 8 (depends on 6) The device of claim 6, wherein a force applied to the device is calculated from data recieved from the one or more force sensors and is uploaded to a remote communication device to alert a different user when the applied excessive force exceeds a selected threshold. ### Claim 9 (depends on 8) The device of claim 8, wherein details of an associated event including a username, date, and time are uploaded in association with the applied excessive force to the remote communication device. ### Claim 10 (depends on 8) The device of claim 8, wherein the notification of the impending collision with the object and the direction of travel of the object is visually conveyed by a display or light. ### Claim 11 (depends on 8) The device of claim 8, wherein the notification of the impending collision with the object and the direction of travel of the object is audibly conveyed by a sound emitted by a plurality of speakers and wherein the plurality of speakers convey to the user a relative current or estimated location of the object by 3D sound synthesis and/or localization techniques. ### Claim 12 (depends on 8) The device of claim 8, wherein the notification of the impending collision is tactilely conveyed by contacting a skin of the user at a location of a potential impact with the object. ### Claim 13 A method comprising: detecting, by wearable device comprising one or more trajectory sensors, an object approaching a user; determining, by a processor in the wearable device, that a collision of the user with the object has at least a threshold likelihood of occurring; and providing, by the processor, an audible, visual, and/or tactile warning to the user of a current or estimated location, travel direction, speed, or acceleration of the object, wherein at least one of the following is true; (i) the step of detecting further comprises detecting multiple objects approaching the user, determining trajectories of each of the multiple objects, and displaying the trajectories of each of the multiple objects on an external display device to be viewed by the user; and (ii) the wearable device uses a communication between other devices for trCking and recording the user's movements. ### Claim 14 (depends on 13) The method of claim 13, further comprising: communicating an applied force applied by a collision of the object with the user to a remote communication device to alert a different user when the applied force exceeds a selected threshold, wherein details of an associated event including a username, date, and time are uploaded in association with the applied force to the remote communication device. ### Claim 15 (depends on 13) The method of claim 13, wherein the warning is visually conveyed by a display or light. ### Claim 16 (depends on 13) The method of claim 13, wherein the warning is audibly conveyed by a sound emitted by a plurality of speakers, wherein the plurality of speakers convey to the user a current or estimated relative location of the object by 3D sound synthesis and/or localization techniques. ### Claim 17 (depends on 13) The method of claim 13, wherein the warning is tactilely conveyed by contacting a skin of the user at a location of a potential impact with the object. ### Claim 18 (depends on 13) The method of claim 13, wherein the warning is tactilely conveyed by vibration device contacting the user at a location of a potential impact with the object. ### Claim 19 (depends on 13) The method of claim 13, further comprising: communicating, to a wearable device of another user, a current or estimated location and/or direction of travel of the wearable device. ### Claim 20 (depends on 13) The method of claim 13, wherein the wearable device comprises a camera for tracking and recording the user's movements. ### Claim 21 (depends on 13) The method of claim 13, wherein the wearable device is incorporated into a sporting event helmet and is worn by a seeing impaired users during a blind sporting event and allows the user to locate an object of play through additional communications directly with said object of play, the object of play comprising a ball or puck.
