1. A work support system for a construction machine including an upper turning body and an attachment attached to the upper turning body, the work support system comprising:
a hardware processor; and
a projector configured to constantly emit light over a fixed distance from the upper turning body in a plurality of directions regardless of a pose of the attachment based on a signal from the hardware processor, the light visualizing information on a ground surface in a vicinity of the construction machine, the plurality of directions including at least one of a direction toward an area to a side of the construction machine or a direction toward an area behind the construction machine,
wherein the projector is configured to emit the light onto the ground surface to irradiate a prohibited area and a caution area with a first light beam and a second light beam, respectively, the first light beam and the second light beam having different colors, the prohibited area being located within a first distance from the construction machine, the caution area being located between the first distance and a second distance from the construction machine, the second distance being longer than the first distance.
