This chapter, which focuses on the acquisition of blind people developing good spatial skills through practice and compensatory task-related strategies, presents the definition of spatial cognition with the importance of vision, the primary sensory modality for spatial cognition. It discusses the reliance of blind people on an ego-centered perspective for embracing the external environment. The methods, including pointing tasks and parallel setting tasks that explain how blind people locate and identify objects near them, are presented, and route-like and survey-like representations used by blind people in identifying and locating objects in the large-scale environment are discussed. The chapter explores the role of individual variables including practice, mental stability, and orientation and the mobility experience, which determines blind people’s spatial cognition ability.

Keywords:   spatial cognition, blind people, task-related strategies, pointing tasks, orientation experience, mobility experience
