Dr. Ozcan Vieira, E.

Assistant Professor 
Industrial Design Engineering


I studied industrial design in Middle East Technical University in Ankara. I worked as a sound designer for a popular radio station (Radyo ODTU) in Ankara, Turkey and as an interaction designer for Novo Design Group in Lisbon, Portugal. In 2003, my academic career started with my PhD study on product sounds in Delft, the Netherlands. At TU Delft, I continue my research on mental processes that underlie sound identification. My other research interests are developing methods and tools to optimize design processes for product sounds. When I have free time from my research activities, I like to take photos, manage the sound of a rock band, and play tennis. I speak Turkish, English, and Portuguese. I am married and dreaming of having my own children.

Specialisation / field of research

Ever wondered why we have a love-and-hate situation with alarm clocks? Or what makes you think that a sports car feels really powerful and therefore very masculine? Or why we get so relax by hearing the squeaky and rough sound of an espresso machine? Many of our daily interactions with products are mediated by the sounds the products emit. Our research has shown that sound is an integral property of a product. That is, product and its sound are functionally and conceptually related. Seeing a product may sensitize auditory information and therefore elicit expectations regarding the adequacy of the sound. Conversely, hearing a product sound may activate conceptual information related to the experiential aspects of product such as the product’s image or its character. Such audio-visual interactions do not only occur on a semantic level but also on an emotional level. Thus, the presence of sound may influence the product experience on an emotional, hedonic, and ergonomic level. But, how do designers deal with product sounds and can these findings guide designers into better product designs?

In a nutshell, my main research interests include:

  • Definition of the domain of product sounds
  • Perceptual and cognitive processing underlying product sound identification
  • The effect of audio-visual interactions on product experience
  • Optimizing the process of product sound design
  • Methods and guidelines for designing product sounds

"Product sounds are the voice of a product. When designing a sound, one should therefore first listen to what the product has to say."
