Infrared cameras are used to visualize a quite abstract context; they can identify the amount of radiation emitted by objects and represent information about their temperature as visual feedback. However, thermography images usually have an erratic and not easily understandable form and users could be burdened and confused when trying to perform certain tasks. The latest development of graphical user interfaces for handheld systems such as mobiles, GPS, etc, has enabled the creation of more rich graphical user interfaces with innovative interaction techniques. The goal of this thesis is to identify where and how innovative interaction techniques can be beneficial to the user experience/usability of handheld IR cameras. This thesis focuses on three critical problem areas, chosen based on specific user tasks, over which prototype solutions are identified and proposed. The outcome of the design process is the implementation of three functional prototypes which in regard to the observations and the analysis made, make use of contemporary interaction techniques in order to combine multiple views of infrared data. The prototypes are developed in C++ and with an XML-like layer for the integration with the user interface and the aimed functionality. The evaluation of the prototypes takes place with the aid of 7 users based on the empirical evaluation and "think aloud" methods. The outcome of the evaluation encourages the idea that multiple views of data combined with the use of different interaction techniques can be beneficial for the understanding of the IR.
