Abstract
A walking aid that projects visual indications corresponding to repositioning of the walking aid. At least one indication for each foot is projected simultaneously. Each indication has dimensions corresponding to a circle or oval. The spacing between each indication can be modified to achieve different step length patterns. Each indication is projected at separate positions on a surface beneath the walking aid. Each position of the separate positions remains relatively static while the walking aid is both stationary and being displaced.

A rollator including:
- a frame having a plurality of wheels;
- a light projector housing mounted to the frame, wherein the light projector housing includes one or more housing apertures facing at least a plane over which the plurality of wheels are in contact;
- a light projector located inside the light projector housing, wherein the light projector rotates proportional to at least one wheel of the plurality of wheels;
- a first bank of LEDs spaced along a first circumferential portion of the light projector and a second bank of LEDs spaced along a second circumferential portion of the light projector, wherein LEDs of the first bank of LEDs and the second bank of LEDs are staggered and offset;
- and
- a power supply electrically connected to the first bank of LEDs and to the second bank of LEDs.

A rollator, comprising:
- a frame having a plurality of wheels;
- a light projector housing, mounted to the frame, that houses a rotating light projector;
- the light projector having a first bank of LEDs including a first plurality of staggered LEDs, and a second bank of LEDs including a second plurality of staggered LEDs, wherein the first bank of LEDs and the second bank of LEDs are offset and positioned on separate circumferential portions of the light projector, and wherein the first bank of LEDs project light adjacent to a first side of the frame and the second bank of LEDs project light adjacent to a second side of the frame;
- and
- wherein the rotating light projector rotates proportionally to rotation of at least one wheel of the plurality of wheels.

A rollator comprising:
- a frame having a plurality of wheels;
- a light projector housing mounted to the frame, wherein the light projector housing includes one or more housing apertures facing at least a plane over which the plurality of wheels are in contact;
- a light projector located inside the light projector housing, wherein the light projector rotates proportionally to a wheel of the plurality of wheels,
- a first bank of lights equidistantly spaced along a first circumferential axis of the light projector and a second bank of lights equidistantly spaced along a second circumferential axis of the light projector, wherein the first circumferential axis and the second circumferential axis are spaced apart and parallel,
- wherein a longitudinal light projector axis, that is perpendicular to, and passes through, the first circumferential axis and the second circumferential axis, passes through only one of a light of the first bank of lights or a light of the second bank lights based on a rotational position of the light projector,
- wherein the first bank of lights are configured to project one or more first projections along a first axis of the plane, and wherein the second bank of lights are configured to project one or more second projections onto a second axis the plane, the first axis and second axis of the plane being parallel and separated by a width that is proportional to spacing between the first and second circumferential axis,
- wherein a widthwise axis, that is perpendicular to, and passes through, the first axis of the plane and the second axis of the plane, passes through only one of a first projection of the one or more first projections or a second projection of the one or more second projections, based on the rotational position of the light projector, and
- wherein the first projection and the second projection are projected simultaneously.
