This study examines the sensitivity of Apple Watch to detect intentional falls from a wheelchair. Twenty-five able bodied (age: 21.9 ± 2.5 years) participated in a protocol in which they intentionally fell out of a wheelchair in a laboratory setting. Each participant wore an Apple Watch Series 5 and performed 3 falls in the forward, right and left sideways, and backward directions onto a crash pad totaling 12 falls each. The Apple Watch was manually checked after each fall to determine if the device registered a fall. From 300 fall trials captured, the Apple Watch detected 14 falls showing a sensitivity of 4.7%, a false negative rate of 95.3%. Logistic regression showed that participant's height, impact force, lower limb functioning, and fall direction are parameters that may influence the ability of the Apple Watch to detect falls from a wheelchair. The Apple Watch fall detection feature presented with a very poor sensitivity to detect intentional falls from a wheelchair among able bodied young adults. Due to the high incidence and consequences of falls, a reliable fall detection device specific for wheelchair users is warranted.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"619-625"},"PeriodicalIF":1.8,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10400435.2021.1923087","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38830678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of the current study was to explore the quantitative contributions of conversation turns and speaking roles in familiar Mandarin Chinese conversation dyads between adults who use SGDs and adults who use natural speech. Five dyads were recruited, and each dyad contained two participants; an adult using an SGD and an adult using natural speech. Each dyadic conversation was individually video-recorded for about 20 minutes, six times. A total of 30 dyadic conversations were analyzed. The means and percentages of the coded conversation turns and speaking roles were computed. Quantitatively asymmetrical contributions of conversation turns and speaking roles occurred in the Mandarin Chinese conversation dyads between the adults who use SGDs and the adults who use natural speech. The adults who use natural speech contributed significantly more conversation turns and speaking roles than did the adults who use SGDs.

Participants included 19 older adults with or without cognitive impairment. We administered cognitive tests assessing all major domains (e.g., memory and attention). Participants were required to listen to robot instructions carefully, and perform three activities of daily living (e.g., taking medicine) with three different types of instructions. In instruction pattern 1 (IP1), the robot informed seniors of the task in one sentence, while in instruction patterns 2 and 3 (IP2 and IP3), the steps of each activity were split into two and three sentences, respectively. Participants with lower cognitive level showed lower task performance with IP1, whereas almost all participants completed tasks with IP2 and IP3. Cognitive domains such as working memory significantly affected task performances. Participants with lower attention made mistakes in taking their medicine. The results imply that step-by-step instructions should be used for older people with lower levels of cognitive function, especially working memory, and repeated instructions may be required for lower attention. Types of instruction should be selected depending on cognitive characteristics.","PeriodicalId":282300,"journal":{"name":"Assistive technology : the official journal of RESNA","volume":" ","pages":"557-562"},"PeriodicalIF":1.8,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/10400435.2021.1893236","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25393653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
