When we walk and interact in an unfamiliar environment, wayfinding can be very challenging. We have to select a proper route than will lead us to the desired destination, we have to orient in our surroundings, we have to monitor our environment while walking to ensure that we are still on the right track and finally we have to recognize the destination. Furthermore, while we are wayfinding, we are acquiring spatial knowledge, developing and enhancing our mental representation of the environment we are interacting in. Assistance aids can be utilized for this purpose, helping us to offload some of the relevant tasks.
