“…The first stage is called alarm, fight or flight, it is the stage on which this study has focused and is the body's immediate response to stress where heart rate, skin conductance and muscle activity increase [1], [2]. In a previous article [3], the authors focused on describing stress and its impact on human life, especially for blind people. Furthermore, this work also described how the human body responds to stress and how stress is related to certain biological signals.…”

Getting around independently on a daily basis is a challenge for blind people. Indeed, when walking outdoors, blind people must avoid many obstacles to reach their destination safely. The difficulty comes from the great variety of the configuration of the environment, with obstacles that can be static or dynamic, and varying levels of danger. Even if the blind person is already familiar with the environment in which they move, the inherent dynamics of the many objects and actors in the environment are still stressful. This article tackles the question of whether there is a link between physiological stress signals and the obstacles that blind users face when navigating paths and routes in daily life. We designed and proposed two prototypes using biological sensors connected to a cane for blind people to collect data in several scenarios. Methods and analysis that were applied on the collected data in order to detect stress will be discussed along with all the results achieved. This work shows that stress can be identified and detected when a blind person is navigating a path, and even that the stress factors causing this stress can be related to obstacles along the path.

“…At each decision point of a route, the blind traveller has to make correct estimations and decisions about their heading to successfully reach a destination, whereas the probability of an erroneous estimation rises with the number of decisions points en route [29]. As blind participants cannot visually adjust those imprecisions e.g., using landmarks, the associated uncertainty can be overwhelming, and often leads to stress, discomfort or even anxiety for the blind [1,[29][30][31]. These negative emotions occur when environmental demands rise beyond the available coping resources.…”

Spatial orientation and navigation depend primarily on vision. Blind people lack this critical source of information. To facilitate wayfinding and to increase the feeling of safety for these people, the “feelSpace belt” was developed. The belt signals magnetic north as a fixed reference frame via vibrotactile stimulation. This study investigates the effect of the belt on typical orientation and navigation tasks and evaluates the emotional impact. Eleven blind subjects wore the belt daily for seven weeks. Before, during and after the study period, they filled in questionnaires to document their experiences. A small sub-group of the subjects took part in behavioural experiments before and after four weeks of training, i.e., a straight-line walking task to evaluate the belt’s effect on keeping a straight heading, an angular rotation task to examine effects on egocentric orientation, and a triangle completion navigation task to test the ability to take shortcuts. The belt reduced subjective discomfort and increased confidence during navigation. Additionally, the participants felt safer wearing the belt in various outdoor situations. Furthermore, the behavioural tasks point towards an intuitive comprehension of the belt. Altogether, the blind participants benefited from the vibrotactile belt as an assistive technology in challenging everyday situations.
