Place This marker functions to indicate the place that will be the user's destination or show the user's standing position. Some examples included in place markers are gates, toilets, counters, etc. 2. Warning This marker functions to inform users that they need to be more careful when walking.

Some objects that are obstacles are holes, poles, railings, etc. 4. Action This marker functions to instruct users to take a certain action according to instructions. Examples of instructions that will be found in the application are “push the door”, “raise your hand to check your body temperature”, etc.
