    This thesis deals with the visual preferences of Japanese Instagram users. Concentrating on the question of whether they prefer photographs with people in them over other types of photo-graphs and what are their reasons for preferring specific photographs. Material used in this study is collected with an online survey and analysed quantitatively and qualitatively with the theories and concepts of cultural studies and semantics in visual communication. Previous studies have shown that people are drawn to human faces, but as photographs with partly covered faces are also common on social media the study focuses on photographs of people where the faces are not fully visible. The survey was conducted online in Japanese language and aimed for Japanese Instagram users. 60 participants answered the survey from which 50 were eligible for the survey. The aim of the survey was to get the participants report their preferred photographs of sets of photo-graphs presented to them, and explain their choices. Gender, age and types of accounts fol-lowed in Instagram are also taken into account in analysis. The participants are mostly of ages 20–29 which makes the data highly the results for the case of these ages. The results show that no clear preference of photographs with people over other kind of photo-graphs is noticed based on the data, but the people as content in a photograph are an important factor for the preference amongst Japanese Instagram users. Other important factors that seem to affect the preference of the Japanese users were colours of the photograph, nature without any indications of people, a clear message of the photograph and highly polished visual appearance in case of food photography.

    The purpose of this study was to examine the pedagogical use of illustrative material in early childhood education. While pictorial material is widely used in early childhood education, there is little research on the topic. The application of pictorial material in supporting communication and structuring everyday function is gaining recognition in early childhood education. The aim of this study was to investigate the pictorial environment of day care centers and the experience of using pictorial material in interactions with children from the kindergarten teachers perspective. Furthermore, the study examines how kindergarten teachers use pictorial material in early childhood education and how they plan the pictorial environment. The research design was qualitative. The research material was collected by theme interviews and photographic documentation. The data included 15 interviews of kindergarten teachers and 613 photographs of their classes. The research material collected end of 2010 in a city in southern Finland. The method used in analyzing both the interviews and the photograph material was theory-guided content analysis. The pictures displayed in the day care environments particularly emphasized everyday functions such as day or week schedules, dressing, eating and play in day care groups. In addition, children's artwork was on display in every classroom. The study suggests that the kindergarten teachers find the pictorial material essential particularly when teaching children with special needs and children who speak Finnish as a second language. However, the teachers noted that they considered the pictorial material beneficial to all children. Kindergarten teachers used pictorial material in everyday life, principally to structure function, guide children's play and support language development. Especially within integrated special groups the communication and participation through pictorial material was seen essential. Kindergarten teachers highlighted that the pictorial environment planning is based on child oriented, function oriented or aesthetic perspectives. The key emphasis in planning the environment is the needs of a particular child or group of children.

    The study examines various uses of computer technology in acquisition of information for visually impaired people. For this study 29 visually impaired persons took part in a survey about their experiences concerning acquisition of infomation and use of computers, especially with a screen magnification program, a speech synthesizer and a braille display. According to the responses, the evolution of computer technology offers an important possibility for visually impaired people to cope with everyday activities and interacting with the environment. Nevertheless, the functionality of assistive technology needs further development to become more usable and versatile. Since the challenges of independent observation of environment were emphasized in the survey, the study led into developing a portable text vision system called Tekstinäkö. Contrary to typical stand-alone applications, Tekstinäkö system was constructed by combining devices and programs that are readily available on consumer market. As the system operates, pictures are taken by a digital camera and instantly transmitted to a text recognition program in a laptop computer that talks out loud the text using a speech synthesizer. Visually impaired test users described that even unsure interpretations of the texts in the environment given by Tekstinäkö system are at least a welcome addition to complete perception of the environment. It became clear that even with a modest development work it is possible to bring new, useful and valuable methods to everyday life of disabled people. Unconventional production process of the system appeared to be efficient as well. Achieved results and the proposed working model offer one suggestion for giving enough attention to easily overlooked needs of the people with special abilities.
