Orientation systems to support indoor travel by persons with multiple disabilities: Technical aspects and applicability issues

Supporting daily activities and indoor travel of persons with moderate Alzheimer's disease through standard technology resources

“…For the other two (i.e., Gail and Amy), the percentages tended to be lower than those obtained previously. The first consideration to make in light of this evidence may be that (a) the data need to be viewed with caution as they concern small groups of patients (i.e., eight with previous technologies and four in Study II), and (b) the different outcomes could be more directly related to the characteristics of the patients and/or of the travel routes than to the technology resources per se (Lancioni et al, 2007). An additional consideration may be that even the data of the less successful patients of Study II suggest a practically relevant performance change that could have implications for the patients (i.e., in terms of enhanced social image and travel opportunities) and their environment (i.e., in terms of objectives considered viable for their daily programs) (Brown et al, 2009;Gibson, MacLean, Borrie, & Geiger, 2004;Lancioni et al, 2012Lancioni et al, , 2013Marquardt & Schmieg, 2009;Sunderland, Catalano, & Kendall, 2009;Tsuchiya & Adolphs, 2007;Wood, Harris, Snider, & Patchel, 2005).…”

Technology-Aided Programs for Persons with Severe/Profound and Multiple Disabilities: A Selective Review

“…A program based on direct orientation cues guides the person's travel by marking or specifying the space to the destination with the automatic presentation of auditory (buzzer-like) sounds, verbal messages, or lights. Such a program is considered appropriate for persons who have a very limited notion of space and virtually no orientation abilities due to combinations of intellectual, neurological and visual disabilities (Lancioni, et al 2007b, Lancioni, Singh, O'Reilly, Sigafoos, Alberti, Scigliuzzo, et al, 2010c. A program based on corrective feedback is much less intrusive than one using directive cues and would be appropriate for persons who have functional vision and/or possess a general notion of the spatial reality surrounding them.…”

“…The two most basic forms of orientation technology rely on the use of direct orientation cues and corrective feedback, respectively (Uslan et al, 1983; Lancioni, Bracalente, & Oliva, 1995; Lancioni, O'Reilly, Singh, Sigafoos, Oliva, Baccani, et al , 2007b). A program based on direct orientation cues guides the person's travel by marking or specifying the space to the destination with the automatic presentation of auditory (buzzer-like) sounds, verbal messages, or lights.…”

A DISLiB based natural language guiding system for assisting visually impaired people in an indoor structured environment

“…For the successful navigation and guidance of visually impaired persons, a well-defined and structured environment is required [15]. This can provide high-rate of precise position and attitude information for reliable estimation of the position and navigational path.…”
