Assessment of Gait and Visual Exploration: Participants will perform walking tasks involving obstacle crossing while their gait and visual exploration patterns are recorded using wearable sensors and eye-tracking glasses. This is a non-invasive observational study with no therapeutic intervention.
Study summary
This study aims to explore how young adults, older adults and people with Parkinson's disease (PwP), perceive their abilty to cross obstacles while walking, and how this perception is related to their actual performance of obstacle crossing and disease-related motor and cognitive impairments. The study will explore this percepeption and the actual performance in different walking environments(floor, synthetic grass turf). Understanding how people perceive obstacles may help improve rehabilitation methods and reduce the risk of falls. The study will take place at the Motor Performance Laboratory, University of Haifa, and will include walking tasks, eye-tracking measurements, and motor and cognitive assessments.

Inclusion Criteria:
* Participants aged 20 to 80 years.
* Ability to walk independently outdoors without assistive devices.
* For Parkinson's Disease (PD) group: Diagnosis of PD confirmed by medical records.
* For healthy control groups: No neurological or orthopedic conditions affecting gait.
Exclusion Criteria:
* Feezing of gait (for PD group only), based on a score greater than 0 on the Freezing of Gait Questionnaire.
* Severe visual impairment that cannot be corrected with glasses or lenses.
* Cognitive impairment, defined as a score below 18 on the telephone-based Mini-Mental State Examination (MMSE).
* Any orthopedic condition, pain, or other medical condition that may affect walking, based on self-report.
Primary outcome measure(s)
Affordance Perception Accuracy — During single laboratory session (about 3 hours) Accuracy of participants' perception of their ability to cross obstacles of varying height and surface conditions. Participants will judge whether they can safely cross an obstacle prior to walking.
Affordances measured by gaze behavior — During a single laboratory session (approximately 3 hours) Eye movement patterns during obstacle approach and crossing. Gaze behavior will be recorded using wearable eye-tracking glasses (Tobii Pro Glasses 3) to assess visual exploration of the walking environment and obstacle. Measures will include fixation(on obstacle) duration (milisecondes).
