Blekinge Tekniska Högskola - BTH

Vår forskning på Managementhögskolan

Vi bedriver forskning inom nästan alla ämnen som finns representerade på sektionen - företagsekonomi, nationalekonomi, sociologi, pedagogik och psykologi.

Den största forskargruppen finns inom företags- och nationalekonomi. Här samlas forskningen under paraplyet

INNOVATION PROCESSES IN INFORMATION ECONOMIES

Vi beskriver området på följande sätt:
"Innovations are important for economic growth and welfare; both the production of innovations and their implementation and use. To understand complex innovation processes, different approaches are used. The research is focused on information economies and includes: the causal relation between information technology and organization and productivity; marketing innovations in industries where standards are important; organizing to develop and implement innovations; investing and financing innovations with uncertain prospects; management control of innovation processes. Our research takes advantage of the university’s focus on information- and communication engineering."

Echolocation of visually handicapped people

Sound is important for how visually handicapped people move and orient in the world. Echolocation is the ability for how blind people and some animals use echoes to detect obstacles through their hearing by the reflection of echoes from objects.  Of importance for a blind person is to get knowledge about the objects that are close-by. There are several factors that are important for how well a blind person can use this ability, e.g. perceptual, acoustical as well as cognitive and experiential ones. Some blind are better than others in using echolocation. Individual factors like intelligence, personality and motivation might contribute. Also among childhood blind there are differences.

In the present project we study some of the important factors, especially the effects of loudness versus pitch, the effects of different number of sound bursts and of noise. Another issue is the precedence effect, since it is important for ordinary sound localizarion. The precedence effect, or the law of the first wave front, makes it possible for us to localize an object to the place from where the sound source is located. This ability should make it hard for blind people to hear echoes in a room, but our brain can under certain conditions ignore this effect. In the project both sighted and blind test persons participate.

The methodology we use is based on principles of experimental psychology, especially from psychophysics. Well defined sounds are presented for observers in a laboratory, where irrelevant disturbances are minimized. Physical signal analysis is conducted on the different sounds. The results are treated with statistical methods, and relations are sought between physical and behavioral measurements. We also would like to explain the individual differences between the visually handicapped in how they use echolocation.

The understanding of human echolocation is important for the design of aids for the blind, how architecture is to be designed and for mobility training of blind persons. The project is funded by Forskningsrådet för Arbetsliv och Socialvetenskap, FAS (Swedish Council for Working Life and Social Research). It is run in collaboration between Blekinge Institute of Technology, Stockholm Uniiversity and the Royal Institute of Technology (KTH).
