More Arguments for Evidence-Based Design (09-25-15)

Zadeh, Sadatsafavi, and Xue completed a comprehensive study of the financial implications of evidence-based healthcare design.  Their article is recommended to people interested in the details of their analyses.  In brief, the team determined that “calculated net present values, internal rates of return, and payback periods indicated that the long-term benefits of [evidence-based design] interventions substantially outweighed the intervention costs. . . .

Fidgeting Can Be a Good Thing (09-24-15)

Trying to incorporate opportunities into a space to move slightly while seated seems like a good idea.  Researchers have learned via studying data collected over many years that “Fidgeting may reduce the risk of all-cause mortality associated with excessive sitting time.”

Younger Urban Residents (09-23-15)

Moos has identified a link between the “densification” of an area and an influx of younger residents; this relationship has many implications for optimal public space design, for example.  As the researcher reports, “The analysis in this paper shows evidence of a youthification process that results in an increasing association of high-density living with the young adult lifecycle stage. The higher density areas remain young over time as new young adults move into neighbourhoods where there are already young people living, and they move out if their household size increases.

Virtual Experiences (09-22-15)

Osimo and her colleagues demonstrate one way in which virtual experiences may improve practice and potentially user experiences, as well.  They report that “When people see a life-sized virtual body (VB) from first person perspective in virtual reality they are likely to have the perceptual illusion that it is their body. . . . In our experiment participants alternately switched between a VB closely resembling themselves where they described a personal problem, and a VB representing Dr. Sigmund Freud, from which they offered themselves counseling.

Sitting Not Good for Children, Either (09-21-15)

A flurry of recent articles have indicated that prolonged sitting is unhealthy for adults and encouraged incorporating opportunities to stand, such as sit-stand desks, into spaces used by them.  Research by McManus and team indicates that it is also undesirable for children (7 to 10 year old girls participated in their study) to sit for extended periods (they compared the health of kids who sat for 3 hours at a time with that of kids who sat for an hour at a time with 10 minutes of exercise every hour).  The findings of McManus and colleagues support incorporating standing options into kids

Optimizing Virtual Museum Experiences (09-18-15)

Sundar and his colleagues investigated experiences in virtual museum galleries and their findings have broad implications for the design of physical museums.  The researchers report that “Museums lean heavily on recent developments in communication technologies to create an authentic experience for online visitors of its galleries. This study examines whether three specific affordances of communication technology—customization [presence vs. absence of customizable gallery], interactivity [presences vs. absence of live chat with others], and navigability [presences vs.

Media Multi-Tasking: Implications (09-17-15)

Using several media devices simultaneously, for example listening to music while using the phone, isn’t a good idea.  Loh and his team have found that “Media multitasking, or the concurrent consumption of multiple media forms, is increasingly prevalent in today’s society and has been associated with negative psychosocial and cognitive impacts. Individuals who engage in heavier media-multitasking are found to perform worse on cognitive control tasks and exhibit more socio-emotional difficulties. . . . .

Sitting Bad for the Liver (09-16-15)

More bad news for people who sit for much of the day.  Research indicates that they have a significantly greater likelihood of developing non-alcoholic fatty liver disease.  In the Ryu, etc., investigation, the group of study participants with the longest sitting times sat for more than 10 hours a day, on average.

Light Color and Thinking (09-15-15)

Weitbrecht and colleagues confirmed the differential implications of experiencing warm or cool light.  Concentration and creativity were tested under three colors of light (3000K [warmer], 4500K, 6000K [cooler]) at the relatively high intensity of 1000 lux.  The researchers determined that “creativity was better under warm light (3000 K) than under colder light (4500 K, 6000 K). Concentration was best under cold light (6000 K).”

Using Scents to Sell (09-14-15)

In an article in the International Journal of Trade and Global Markets, Chatterjee recommends using scents to support branding in commercial spaces.  As a press release related to his article details, “Smells trigger immediate emotional responses and marketing departments the world over have exploited this everywhere from supermarkets to car showrooms. . . . .Chatterjee . . . [reports that] ‘scent makes a brand identity more unique, strengthens customer loyalty and adds to the perception of quality, an element that is essential to every brand in today’s competitive market.’ . . .
