- ItemAn accelerometer-based handheld system to reduce breaks in performance of young adults with cognitive impairments.(2011-10-11) Chang, Yao-Jen; Chen, Shu-Fang; Lu, Zhi-ZhanThis study assessed the possibility of training two individuals with cognitive impairments using a system that reduced breaks in performance This study was carried out according to an ABAB sequence in which A represented the baseline and B represented intervention phases Data showed that the two participants significantly increased their target response thus reducing breaks and improving vocational job performance during the intervention phases Practical and developmental implications of the findings are discussed
- ItemAutonomous indoor wayfinding for individuals with cognitive impairments.(2010-09-29) Chang, Yao-Jen; Peng, Shu-Ming; Wang, Tsen-Yung; Chen, Shu-Fang; Chen, Yan-Ru; Chen, Hung-ChiBACKGROUND A challenge to individuals with cognitive impairments in wayfinding is how to remain oriented recall routines and travel in unfamiliar areas in a way relying on limited cognitive capacity While people without disabilities often use maps or written directions as navigation tools or for remaining oriented this cognitively impaired population is very sensitive to issues of abstraction e g icons on maps or signage and presents the designer with a challenge to tailor navigation information specific to each user and context METHODS This paper describes an approach to providing distributed cognition support of travel guidance for persons with cognitive disabilities A solution is proposed based on passive near field RFID tags and scanning PDAs A prototype is built and tested in field experiments with real subjects The unique strength of the system is the ability to provide unique to the user prompts that are triggered by context The key to the approach is to spread the context awareness across the system with the context being flagged by the RFID tags and the appropriate response being evoked by displaying the appropriate path guidance images indexed by the intersection of specific end user and context ID embedded in RFID tags RESULTS We found that passive RFIDs generally served as good context for triggering navigation prompts although individual differences in effectiveness varied The results of controlled experiments provided more evidence with regard to applicabilities of the proposed autonomous indoor wayfinding method CONCLUSIONS Our findings suggest that the ability to adapt indoor wayfinding devices for appropriate timing of directions and standing orientation will be particularly important
- ItemA feasibility study of enhancing independent task performance for people with cognitive impairments through use of a handheld location-based prompting system.(2013-09-30) Chang, Yao-Jen; Chen, Shu-Fang; Chou, Li-DerAn autonomous task prompting system is presented to increase workplace and life independence for people with cognitive impairments such as traumatic brain injury intellectual disability schizophrenia and Down syndrome This paper describes an approach to providing distributed cognition support of work engagement for persons with cognitive disabilities In the pilot study a prototype was built and tested in a community based rehabilitation program involving pre service food preparation training of 8 participants with cognitive impairments The results show improvement in helping with task engagement is statistically significant compared to the oral instruction method A follow up comparative study with 2 participants evaluated the shadow team approach against the proposed system Although the number of participants was few the participants were studied in depth and the findings were very promising The results in the autonomous task prompting without staff intervention indicate that the performance is statistically as good as the shadow team approach Our findings suggest that acquisition of job skills may be facilitated by the proposed system in conjunction with operant conditioning strategies
- ItemA location-based prompting system to transition autonomously through vocational tasks for individuals with cognitive impairments.(2011-10-11) Chang, Yao-Jen; Wang, Tsen-Yung; Chen, Yan-RuThis study assessed the possibility of training two individuals with cognitive impairments using location based task prompting system in a supported employment program This study was carried out according to an ABAB sequence in which A represented the baseline and B represented intervention phases Data showed that the two participants significantly increased their target response thus improving vocational job performance during the intervention phases Practical and developmental implications of the findings are discussed
- ItemMobile social network services for families with children with developmental disabilities.(2011-07-19) Chou, Li-Der; Lai, Nien-Hwa; Chen, Yen-Wen; Chang, Yao-Jen; Yang, Jyun-Yan; Huang, Lien-Fu; Chiang, Wen-Ling; Chiu, Hung-Yi; Shin, Haw-YunAs Internet technologies evolve their applications have changed various aspects of human life Here we attempt to examine their potential impact on services for families with developmentally delayed children Our research is thus designed to utilize wireless mobile communication technologies location services and search technology in an effort to match families of specific needs with potential care providers Based on the investigation conducted by our counselors this paper describes a platform for smooth communication between professional communities and families with children with developmental disabilities CDD This research also looks into the impact of management of mobile social network services and training on the operation of these services Interaction opportunities care and support to families with CDD are introduced
