The purpose of this thesis is to investigate how Digital Signage systems such as public info kiosks can be designed to better fulfill its main use; to enlighten, encourage and influence the public with information. The challenges presented from earlier studies shows that the public interests and goals, together with proper and relevant content displayed in info kiosks have impact on the attention the public have towards public displays. Qualitative methods such as interviews, usability testing and observations were conducted to further examine how a public info kiosk can be designed to draw attention and grow interest amongst students at K3, Malmo University. Usability testing were used on the digital prototypes that were developed to ensure that the gestural user interface meet the requirements of a proper interaction from the users. Important insights were made concerning; the attention and interest to relevant content, the aspects of the gestural user interface along with the placement of the info kiosk in terms of context. These key factors need to be properly investigated and developed to ensure a better deployment of a public info kiosk. It is suggested that using the principles of interaction design by doing research and studies of public interest and needs, and optimizing it by taking the specific context of place and time in account when a designing content. The results from this thesis suggests that an installation of a public info kiosk will successfully earn the attention and interest from the public if the content is relevant and interesting to the specific public. It is also important that the systems perform well in terms of software and hardware to allow a fluid and intuitive interaction with the gestural user interface.
