A processing system for a motorized mobile system includes at least one sensor to measure one or more kinematic states of an object proximate to the motorized mobile system and at least one processor to use at least one state estimation filter and at least one object kinematic model. The processor uses the at least one state estimation filter and the at least one object kinematic model to predict a first kinematic state estimate of the object based on a prior knowledge of state for the object and output the predicted first kinematic state estimate of the object from the state estimation filter for use by at least one other process of the motorized mobile system, wherein the at least one other process causes one or more actions to be taken by the motorized mobile system based on the predicted first kinematic state estimate of the object. The processor further uses the at least one state estimation filter and the at least one object kinematic model to receive a measured kinematic state of the object observed by the sensor, use the predicted first kinematic state estimate of the object and the measured kinematic state of the object observed by the sensor to determine a second kinematic state estimate of the object, and use the second kinematic state estimate of the object as an input to the state estimation filter using the object kinematic model to predict another kinematic state estimate of the object.

The present disclosure describes a system, device, and method for assisting a user to avoid contacting surfaces with their mobile device. An environment is sensed with one or more electronic sensors. The sensor readings are analyzed. Information is then provided to a user based on the analyzed sensor readings. The sensors may be configured so their sensor cones cross at a midpoint. Readings from the sensor(s) may be grouped according detection zone(s) corresponding to one or more areas about a mobile device. A computing module may control a feedback module according to detection zone readings. The feedback module may comprise an indicator for each detection zone. The indicator may be a vibration motor. The indicator may be a light. The computing module may set the colour of a light and/or control the vibrations based on the proximity of surfaces detected within the corresponding detection zone.
