Qualitative Research

One of the strong points of DTR is the specialty of its team in organizing and conducting qualitative research for international clients.

DTR presents HV usually as a complementary tool for IDIs, FGD and F2F studies. Strong moderating, high-quality simultaneous interpreting, HD audio and video recording are guaranteed.     


Eye Tracking

Based on reliable studies in the field of neuroscience, eye movements disclose more than personal accounts. It’s an effective tool to spice up advertisement campaigns, merchandizing and product design with creativity. In this method, we let respondents share their unconscious mind with us. By this unique technique, we see the world around them through their own eyes.


Advertisement & Merchandizing

Do you want to know what they see and capture through their glances? Eye tracking is the tool which is developed for this purpose i.e. to discover the visual strong and weak points of advertisements and product displays. We make use of hi-tech user-friendly eyeglasses to capture respondents’ eye movements so that we could analyze the movements by specialized computer software. To make data more reliable, we conduct interviews with the respondents whose eyes’ movements are recorded and analyzed. Finally, a reliable executive report will be submitted to clients regarding their advertisement campaigns and merchandizing.


 Home Appliance Design

 Are you interested in how respondents investigate your products on display when they come to buy home appliances? We will tell you all by Eye Tracking Technology. Eye Tracking service helps you strengthen the design of those parts which capture the eyes the most.


Desk Research

Sometimes clients heavily invest on fieldworks while they could have obtained the data they were looking for through a cost effective desk research by a local agency. Desk research can be a complementary tool when clients want to obtain preliminary understanding of Iranian market through qualitative research. Desk research is recommended to newcomers to Iranian market .


Market & Industry Analysis
