Modifying the Work Environment and the Home Environment

Modifying the Work Environment and the Home Environment
is another chapter in Nurturing the Older Brain and Mind by Greenwood and Parasuraman.  It covers research in the field of Human Factors and Ergonomics.  I am a longstanding member in the Human Factors and Ergonomics Society.  The field of Human Factors and Ergonomics is devoted to designing technologies and environments so that they can be used effectively and safely.  Greenwood and Parasuraman note that their coverage of the broad area of human factors and ergonomic design for older adults is limited to just a few topics, including health-care technologies aimed at older adults and assistive technologies for the home.  They do provide references for more general coverage of basic research issues in human factors and aging.  There is much research into sensory-perceptual factors and interface designs and devices to compensate for losses in both sensory and motor functions that are not provided in the book.

Assistive technologies for self-care and “aging in place” are being developed.  This is especially important because more that 90 % of older adults live in their own homes, with relatives, or in independent-living facilities.  Older adults living alone are of special concern.  Some older people  have banded together so that they can age-in-place.  They organize self-help “villages” to screen service providers (repair technicians, for example) and other direct services such as meal delivery to dues-paying members.

The proper design of these assistive technologies has special importance for the elderly.  Daily we interact with and are frustrated by poorly designed devices (and software).  This frustration is exacerbated in the elderly who may abandon the use of the technology or, worse yet, use it improperly.

The Georgia Institute of Technology has been at the forefront of research to introduce “intelligent” technologies to help older adults age in place.  They have developed what they term the “Aware Home”, which is a conventional appearing house with many sensing and computing infrastructure designed to keep older individuals safe and improving their lives.  Information can be sent to a friend or relative to keep them aware of where the individual is in the house and what they are doing.

Honeywell has developed an Independent Living Lifestyle Assistant (ILSA)to support an independently living  older person with extensive monitoring and management (including the monitoring of temperature, blood pressure, and heart rate)  and with the ability to control remotely lights, power, a thermostat, door locks, and water flow.  There are many sensitive issues implementing these systems indicating that more research needed to be done.  Overreliance and complacency are two of the problems that need to be addressed.  Continued research will yield improved systems, and technology can be employed in an a ad hoc manner.  Imagine using Skype to keep tabs regularly on an older friend or relative.   Enter “Aging in Place Technology Watch”  to learn of a large range of activities taking place in this area. offers a wide range of information and products
