Facilitating interdisciplinary design specification of "smart" homes for aging in place.

"Smart homes" are defined as residences equipped with sensors and other advanced technology applications that enhance residents' independence and can be used for aging in place. The objective of this study is to determine design specifications for smart residences as defined by professional groups involved both in care delivery to senior citizens and development of devices and technologies to support aging. We assessed the importance of specific devices and sensors and their advantages and disadvantages as perceived by the interdisciplinary expert team. This work lays the ground for the implementation of smart home residencies and confirms that only an interdisciplinary design approach can address all the technical, clinical and human factors related challenges associated with home-based technologies that support aging. Our findings indicate that the use of adaptive technology that can be installed in the home environment has the potential to not only support but also empower individual senior users.

Home-based assistive technologies for elderly: attitudes and perceptions.

This study aim is to explore the perceptions of seniors in regard to "smart home" technology aiming to improve their quality of life and/or monitor their health status. A total of 15 older adults participated in three focus groups. Participants had a positive attitude towards these technologies and identified application areas such as emergency help, detection of falls, monitoring of physiological parameters. Concerns were expressed about privacy and the need for tailored training.

Older adults' attitudes towards and perceptions of "smart home" technologies: a pilot study.

PRIMARY OBJECTIVE: The study aim is to explore the perceptions and expectations of seniors in regard to "smart home" technology installed and operated in their homes with the purpose of improving their quality of life and/or monitoring their health status. RESEARCH DESIGN AND METHODS: Three focus group sessions were conducted within this pilot study to assess older adults' perceptions of the technology and ways they believe technology can improve their daily lives. Themes discussed in these groups included participants' perceptions of the usefulness of devices and sensors in health-related issues such as preventing or detecting falls, assisting with visual or hearing impairments, improving mobility, reducing isolation, managing medications, and monitoring of physiological parameters. The audiotapes were transcribed and a content analysis was performed. RESULTS: A total of 15 older adults participated in three focus group sessions. Areas where advanced technologies would benefit older adult residents included emergency help, prevention and detection of falls, monitoring of physiological parameters, etc. Concerns were expressed about the user-friendliness of the devices, lack of human response and the need for training tailored to older learners. CONCLUSIONS: All participants had an overall positive attitude towards devices and sensors that can be installed in their homes in order to enhance their lives.

Qualitative analysis of sketched route maps: translating a sketch into linguistic descriptions.

In this correspondence, we introduce our work on sketch understanding, focusing here on the analysis of a sketched route map. A route map is drawn to help someone navigate along a path for the purpose of reaching a goal. A hand-sketched route map does not generally contain complete map information and is not necessarily drawn to scale, but yet it contains the correct qualitative information for route navigation. Here we propose a methodology for extracting a qualitative model of a sketched route map, based on human navigation strategies, using spatial relationships. Linguistic descriptions are generated from the sketch, both in the form of detailed descriptions at discrete path steps and also as a high-level route description. To describe the path linguistically, one must first be able to understand the path in a qualitative sense. We assert that the translation of a sketch into linguistic descriptions illustrates that the essential qualitative path knowledge has been extracted. The methodology is demonstrated using example sketches drawn on a handheld PDA.

Detection of lameness and determination of the affected forelimb in horses by use of continuous wavelet transformation and neural network classification of kinematic data.

OBJECTIVE: To investigate continuous wavelet transformation and neural network classification of gait data for detecting forelimb lameness in horses. ANIMALS: 12 adult horses with mild forelimb lameness. PROCEDURE: Position of the head and right forelimb foot, metacarpophalangeal (ie, fetlock), carpal, and elbow joints was determined by use of kinematic analysis before and after palmar digital nerve blocks. We obtained 8 recordings from horses without lameness, 8 with right forelimb lameness, and 8 with left forelimb lameness. Vertical and horizontal position of the head and vertical position of the foot, fetlock, carpal, and elbow joints were processed by continuous wavelet transformation. Feature vectors were created from the transformed signals and a neural network trained with data from 6 horses, which was then tested on the remaining 2 horses for each category until each horse was used twice for training and testing. Correct classification percentage (CCP) was calculated for each combination of gait signals tested. RESULTS: Wavelet-transformed vertical position of the head and right forelimb foot had greater CCP (85%) than untransformed data (21%). Adding data from the fetlock, carpal, or elbow joints did not improve CCP over that for the head and foot alone. CONCLUSIONS AND CLINICAL RELEVANCE: Wavelet transformation of gait data extracts information that is important for the detection and differentiation of forelimb lameness of horses. All of the necessary information to detect lameness and differentiate the side of lameness can be obtained by observation of vertical head movement in concert with movement of the foot of 1 forelimb.

A technology and nursing collaboration to help older adults age in place.

This is an account of an active collaboration between Computer Engineering, Health Informatics, and Nursing within an academic health science center to improve the quality of life of older adults as they "age in place." The Sinclair School of Nursing at the University of Missouri-Columbia has developed a licensed home health agency, Senior Care, to provide the care needed by residents of TigerPlace, a specially designed independent living center near the University. Technology has the potential to help address common problems encountered by older adults related to functional decline. Collaboration between Nursing, Computer Engineering, and Health Informatics is likely on a path to improve the quality of life of seniors.
