||The constant development of the mobile devices, especially mobile phones, implies the increase
in the image quality of taken photos. As the result, the size of personal image collections is very
likely to expand in the coming years. Existing solutions, although sufficient today, will become
inappropriate for management of collections of thousands of files. The suggestion was to
implement a new application, which is based on the tagging concept. In order to address the
problem with the image annotation, the concept of context awareness was exploited. It used
various contextual data, available through the numerous sensors included in modern mobile
The scope of the project includes a theoretical research, a users survey, experiments with
contexts and a prototype’s design, implementation and evaluation.
The survey’s results revealed that time, place, events, and people belong to the most desired
viewing and searching options. The field experiments have indicated that the use of Cell ID for
location discovery is sufficient for the purpose of content management. The tests that followed
showed that the accuracy of the determined place may be problematic in photo management.
The last experiment indicated that GPS is the most battery consuming context, WLan is in
second place, and Bluetooth is last.
Based on the findings from the survey and the experiments the functional prototype has been
implemented. The novelty features in mobile solution are views by place/city, event, days,
weeks and months. Additionally, the prototype serves two searching functions: by various
criteria and for the similar images. The evaluation confirmed a very good performance of the
new approach and its appropriateness for the large image collections on mobile phone.
