Older adults' communication with an interactive humanoid robot : Expectations and experiences of older adults in verbal and nonverbal communication with a socially interactive humanoid robot: a mixed methods design in Germany.

BACKGROUND AND OBJECTIVE: One possible approach to counter singularization and loneliness of older adults is the development and implementation of socially interactive robots. Little is known about the expectations and experiences of older adults with socially interactive humanoid robots. MATERIAL AND METHODS: In a mixed-methods design study, user expectations before interaction and the experience and evaluation of verbal and non-verbal communication after interaction with a robot were assessed. Semi-structured interviews were conducted after the interaction. RESULTS: The majority of older adults expected verbal communication. After the interaction the evaluation of the quality of verbal communication differed. Participants did not expect any form of nonverbal communication. Nonverbal communication was highlighted as particularly positive. Gestures, facial expressions, and body movements were described as confidence building. CONCLUSION: The robot's ability to communicate nonverbally might positively influence older adults' experience of communication with the robot. In the development of socially interactive robots non-verbal communication should be given more consideration in order to contribute to successful human-robot interaction.

Evaluation of the quality and the provision process of wheelchairs in Germany. Results from an online survey.

BACKGROUND: Restrictions in mobility can lead to social and health-related issues. Assistive technologies and devices can help to sustain or regain mobility in affected persons. One of the most commonly used devices is the wheelchair. Many wheelchair users experience difficulties within the provision process and with the device itself. The presented study investigated the satisfaction with the wheelchair and the corresponding provision process. METHODOLOGY: A comprehensive online survey was conducted. The questionnaire surveyed the quality of wheelchairs and the corresponding provision process among wheelchair users in Germany. Descriptive methods were used to analyse the results. Sub-groups were classified according to age, sex, waiting time for wheelchair, financing and type of wheelchair. RESULTS: After cleaning the data, 110 datasets remained for analysis. The predominant reasons for wheelchair acquisition were independence and the replacement for a defective wheelchair. Wheelchair quality aspects as well as the corresponding provision process were rated medium. Issues were found regarding waiting times, repair services and communication between service providers. DISCUSSION: The presented results reflect issues in the quality of wheelchairs and their provision process. Inequality between different sub groups is evident. Although some results should be considered with caution due to unequal group sizes, clear trends can be seen which confirm results from other studies throughout the literature. CONCLUSION: The presented cross-sectional study results give an important overview about the user satisfaction with the quality and provision process of wheelchairs. A longitudinal study accompanying users during the provision process is being recommended as a more in-depth study.IMPLICATIONS FOR REHABILITATIONLow durability and adaptability were identified as main issues regarding wheelchair quality.Waiting times for wheelchairs were perceived as too long by the users and make up the main factor for low satisfaction with the wheelchair provision process.Reduced waiting times for wheelchairs (especially for electric wheelchairs) can improve overall satisfaction with the assistive device.Waiting times could be reduced by a more efficient application and provision process.

Assistive Robots for Patients With Amyotrophic Lateral Sclerosis: Exploratory Task-Based Evaluation Study With an Early-Stage Demonstrator.

BACKGROUND: Although robotic manipulators have great potential in promoting motor independence of people with motor impairments, only few systems are currently commercially available. In addition to technical, economic, and normative barriers, a key challenge for their distribution is the current lack of evidence regarding their usefulness, acceptance, and user-specific requirements. OBJECTIVE: Against this background, a semiautonomous robot system was developed in the research and development project, robot-assisted services for individual and resource-oriented intensive and palliative care of people with amyotrophic lateral sclerosis (ROBINA), to support people with amyotrophic lateral sclerosis (ALS) in various everyday activities. METHODS: The developed early-stage demonstrator was evaluated in a task-based laboratory study of 11 patients with ALS. On the basis of a multimethod design consisting of standardized questionnaires, open-ended questions, and observation protocols, participants were asked about its relevance to everyday life, usability, and design requirements. RESULTS: Most participants considered the system to provide relevant support within the test scenarios and for their everyday life. On the basis of the System Usability Scale, the overall usability of the robot-assisted services for individual and resource-oriented intensive and palliative care of people with ALS system was rated as excellent, with a median of 90 (IQR 75-95) points. Moreover, 3 central areas of requirements for the development of semiautonomous robotic manipulators were identified and discussed: requirements for semiautonomous human-robot collaboration, requirements for user interfaces, and requirements for the adaptation of robotic capabilities regarding everyday life. CONCLUSIONS: Robotic manipulators can contribute to increase the autonomy of people with ALS. A key issue for future studies is how the existing ability level and the required robotic capabilities can be balanced to ensure both high user satisfaction and effective and efficient task performance.

Acceptance of Enhanced Robotic Assistance Systems in People With Amyotrophic Lateral Sclerosis-Associated Motor Impairment: Observational Online Study.

BACKGROUND: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease characterized by a progressive paresis of the extremities and the loss of manual functioning. Due to the severe functional impairment that the disease entails, ALS requires the provision of comprehensive nursing care and a complex set of assistive technology devices. To relieve caregivers and promote autonomy of people with ALS, robotic assistance systems are being developed. This trial aims to evaluate the acceptance of technology, in general, and of robotic arm assistance among people with ALS in order to lay the groundwork for the development of a semiautomatic robotic arm that can be controlled by humans via a multimodal user interface and that will allow users to handle objects and attend to their own bodies. OBJECTIVE: The aim of this study was to perform a systematic analysis of technology commitment and acceptance of robotic assistance systems from the perspective of physically limited people living with ALS. METHODS: The investigation was conducted as a study of a prospective cohort. Participants were only included if they had received a medical diagnosis of ALS. Data collection took place via an online questionnaire on the Ambulanzpartner Soziotechnologie internet platform. Technological commitment was measured using the Neyer short scale. Furthermore, a multidimensional questionnaire was specially developed to analyze participant acceptance of robotic arm assistance: the Acceptance Measure of Robotic Arm Assistance (AMRAA). This questionnaire was accompanied by a video introducing the robot arm. ALS severity was ascertained using the ALS Functional Rating Scale-Extended (ALSFRS-EX). RESULTS: A total of 268 people with ALS participated in the survey. Two-thirds of the participants were male. The overall mean ALS severity score was 42.9 (SD 11.7) points out of 60 on the ALSFRS-EX, with the most relevant restrictions on arms and legs (<60% of normal functioning). Technological commitment ranked high, with the top third scoring 47.2 points out of 60. Younger participants and males showed significantly higher values. The AMRAA score was, again, significantly higher among younger participants. However, the gender difference within the overall cohort was not significant. The more limited the arm functioning of participants according to the ALSFRS-EX subscale, the higher the acceptance rate of robotic assistance. This relationship proved significant. CONCLUSIONS: People with ALS display high technological commitment and feel positive about using technological assistance systems. In our study, younger participants were more open to technology use, in general, and robotic assistance, in particular. Self-appraisal of technology acceptance, competence, and control conviction were generally higher among men. However, any presumed gender difference vanished when users were asked to rate the anticipated usefulness of the technology, in particular the robotic arm. The acceptance was also reflected in users' increased willingness to use a robotic arm as the functionality of their own arms decreased. From the perspective of people with ALS, robotic assistance systems are critical to promoting individual autonomy. Another key consideration in the development of future assistive technologies should be the reduction of caregiver burden.

[Ethical implications in the development of functional training in mixed and augmented reality environments to treat hypertension in old age: A qualitative content analysis]. / Ethische Implikationen in der Entwicklung eines funktionellen Trainings in einer Mixed- und Augmented Reality Umgebungen zur Behandlung von Hypertonie im Alter: Eine qualitative Inhaltsanalyse.

BACKGROUND: E-Health is of increasing importance in ensuring demand-oriented health care. In addition to technical feasibility, issues concerning the normative requirements for their use are growing. This paper discusses the ethical, legal and social implications of the use of mixed reality (MR) and augmented reality (AR) technologies in the therapy of elderly people with hypertension. It is based on the results of a study conducted as a part of the BMBF project BewARe. METHODS: In the context of the above-mentioned background, an expert workshop was held with various stakeholders in an early phase of the BewARe project in accordance with the MEESTAR model, in which ethical, social and legal requirements for the development and use of AR/MR technologies were anticipated. The results of the workshop were subsequently evaluated using content analysis. RESULTS: Content analysis identified eight main challenges for the development and use of AR/MR technologies in the therapy of elderly people with hypertension: ethical challenges for the decision-making and action capacity of older users (1), stereotyping (2), user-oriented development and implementation (3), data protection (4), support (5), health risks (6), social participation (7), and the need for an integrative approach (8). DISCUSSION: In line with other studies, it can be shown that orientation towards medical guidelines and behavioral principles is essential to promote acceptance and adherence among end users and to minimize potential health risks. In addition, end users should be more strongly involved in the development process to overcome existing user stereotypes and establish qualification strategies for health-promoting use. Finally, legal and health economic framework conditions must be created to ensure data security and sustainable application concepts. CONCLUSION: For a successful diffusion of AR/MR applications in health care, a holistic implementation concept is required which must involve various groups of social actors. In this context, the article discusses eight main challenges that can be understood as current challenges in this process.
