Human-Computer Interaction (HCI) research refers to the process of understanding and identifying the way people use computer technology and tools (e.g. software, web sites). By mapping this interaction and applying the acquired knowledge, user-friendly interfaces can be designed and improved. For that purpose, mouse and keyboard use can be recorded, as well as interesting actions of the user, such as verbal expressions. This can be accomplished by using The Observer® XT and uLog™.
To ensure efficiency in your usability studies, you need to give feedback to the development teams rapidly. At the same time, presentation of you results needs to be convincing to prevent that all efforts of recruiting test persons, setting up facilities, and testing are wasted! Since development processes often take place under time pressure, project leaders are generally unfavorably disposed towards delaying product releases due to the need to implement usability improvements. If you want your voice to be heard, you need hard evidence of the issues of improvement you found and you need it fast. That is exactly what The Observer® XT can do for you.
It is often the combination of behavioral data with other data modalities, such as physiological data, that makes research most valuable. That is why using The Observer® can take your research to a higher level: it offers fl exible integration of your logged events with other modalities such as eye tracking data.
specific situations is indispensable. This leaflet shows you how The Observer® XT facilitates the study of consumer behavior, and helps to increase the quality and efficiency of observational research.
Lorraine Ann Randall (Washington, DC, U.S.A). The U.S. Bureau of the Census collects general demographic and economic information, using censuses and surveys. These surveys are done either using paper or software forms.
Both types of forms have to meet high standards in terms of comprehensibility, accessibility and clearness. During an exploratory usability test, the test subjects are observed while completing a questionnaire. The Observer Video-Pro is used to record behavior on video and for the analysis afterwards.

Hose handling, opening and closing manholes, turning switches and coupling railway wagons by hand: this is all heavy work, and the physical load of the so-called 'movement operators' who do this job, is an important concern for their companies. The aim of this study was to draw up and justify possible plans to optimize their work situation and reduce their physical load.
The pysical load of the 'movement operators' was assessed by use of a Hierarchical Task Analysis (HTA). The methods for HTA are interviews with workers and management, and observation of actual operations. Observations were performed using both The Observer Mobile (with a Psion Workabout handheld computer) and The Observer Video-Pro.
Structured observation of human behavior is a widely accepted method to gather information about how people perform a task or interact with each other. However, a problem arises if one wishes to measure someone’s behavior under circumstances that are not available ‘live’ or cannot be reproduced in front of a video camera. In this review you can read how virtual reality and The Observer can be applied to overcome these problems.
As civil air is rapidly growing, most large airports are under constant reconstruction and expansion. In order to minimize waiting times before departure and between connecting flights, the ever-increasing stream of airplanes, passengers and luggage must be led into the right channels.
To this end the KLM Controllers Service Management Schiphol is constantly analyzing the processes related to the arrivals and departures of the aircraft, i.e. all the passenger-related activities. The Observer enabled the optimalization of allocating time and work force on each of these activities.
