Mobility aid

A system for aiding a user to move, comprising:

• a first sensor in the form of footwear or an attachment for footwear and configured to detect a first parameter indicating a position of the user's foot, wherein the first sensor is a pressure sensor configured to detect a pressure exerted by the user's foot on a surface;
• a second sensor, wherein the second sensor is a distance sensor configured to detect a distance parameter;
• a projector operable to project a first visual cue, the first visual cue is a line projection in the form of a line in front of the user, wherein the projector is configured to be rotated ninety degrees between a first orientation and a second orientation such that when the projector is in the first orientation the line is projected vertically in front of the user and when the projector is in the second orientation the line is projected horizontally in front of the user, wherein a processor of the system controls operation of the projector depending on the first parameter detected by the first sensor;
• wherein the projector is further operable to project a second visual cue in the form of a dot projection for highlighting obstacles;
• wherein the processor is configured to enable the first visual cue when the pressure detected by the first sensor exceeds a pressure threshold and to enable the second visual cue when the pressure detected by the first sensor is below the pressure threshold;
• and wherein the processor is further configured to enable at least one of the first and second visual cues when the distance detected by the distance sensor is below a distance threshold.
