This is an attempt to analyze the evaluation criteria of tactual qualities on handheld product experiences by users. The study was conducted with the users selected from different work groups and different ages for exploring the meanings which are attributed to these tactual qualities by them. The thesis is expected to shed a light in the design studies by designers. After identifying the products and the participants, the tactual experiences were analyzed throughout the study to find out the keywords which are used to describe the tactual qualities through the experience. The evaluation criteria and the relationships between these criteria are expected to use as guidance. The guidance of these keywords, the approaches of the users to the tactual qualities tried to be clarified in order to acquire data for the design processes. The results showed that the tactual qualities are qualities which are mentioned by the participants. This means that the participants are aware of the tactual qualities. On the other hand, it was seen that expressing the emotional effects of the tactual qualities with words is hard for users. However, expressing the emotional effects is hard for users / some relations between the tactual qualities and between other qualities are conducted.

Intersensory transfer of training was systematically investigated for visual to tactual and tactual to visual situations. College students were trained in one modality on a successive-shape-discrimination task, then transferred to the opposite modality to perform a related-shape-discrimination task. The investigation showed successful transfer in both directions, Transfer from vision to touch was specific to the situation wherein all discriminata were exactly the same In the two tasks. In contrast, transfer from touch to vision appeared to be a function of the subjects' ability to retain some type of schematic representation of the primary object as a mediational device to facilitate visual discrimination between the primary object and one of a slightly different shape.

This diploma thesis addresses the topic of tactile perception examined in the cases of children with severe visual impairment as well as in the cases of blind children aged from three to six years. Tactile perception is assessed by the Tactual Profile test. The introduction of this thesis briefly summarizes the issue of visual perception, specifics of development of a pre-school child with a visual impairment, tactile perception and other compensating senses, and the importance of play in the pre-school period. The second part of this thesis is focused on the Tactual Profile test and its description. The following part is dedicated to research based on applying the aforementioned method of the non- standardized Tactual Profile test. The test, or more precisely the testing tool, is used for diagnosing the level of tactile development among children with severe visual impairment and among blind children. The test results provide the possibility to assess the status of tactile perception of the specific child and determine areas which are challenging for the child as well as areas in which the stated child excels. The goal of this research was to ascertain the applicability of the test regarding the target group and examine its potential utilization in the special education practice. The research also...

This diploma thesis is focused on the problematics of examination of tactile perception in older school-age pupils with severe visual impairment. The thesis has got three main parts. The first part deals with tactile perception, defines its main characteristics, properties and obstacles associated with tactile perception. It also deals with the role of touch in the life of pupils with visual impairment. A large part of this chapter focuses on the description of orientation aids for visually impaired students. In conclusion, there are mentioned the diagnostic instruments by which the tactile perception is judged. The second part deals with the Tactual Profile observation instrument. There is a detailed description of its purpose and use and there are also mentioned foreign studies on this instrument of Dutch origin. The practical part includes the study of the level of tactile perception in school-aged pupils with visual impairment through the Tactual Profile test. The aim of this diploma thesis is to determine the functionality and usability of this test material (Tactual Profile) in praxis in the given age group of pupils and students with visual impairment. Keywords Tactile perception, touch, visual impairment, Tactual Profile test, school age, older school-age pupils, diagnostics, blindness.

Este trabalho teve dois objetivos : verificar se a emissão de Tatos face a figuras variava segundo a dimensão cor, e estudar o vocabulário do pré-escolar.Para tal, trabalhou-se com 48 sujeitos, de quatro,cinco e seis anos. Em cada faixa etária havia dois sub-grupos, igualmente constituídos, quanto ao sexo e número de sujeitos, sendo a única diferença a ordem de apresentação do material colorido e preto-branco. o material consistiu de dois tipos de figuras: pranchas do PLDK -nível P (três séries), apresentadas coloridas e preto-branco e uma gravura. As crianças foram testadas individualmente em duas sessões. Os resultados indicam que: no PLDK nível P - a) de modo geral, não houve diferença de desempenho face as pranchas preto-branco e coloridas; b) houve várias correlações significantes entre cada série e o total, embora poucas inter-séries; c)quanto a seqüência de apresentação, apenas o grupo de quatro nos revelou ganho na seqüência preto-branco considerando a variável idade, de forma geral os mais novos tiveram desempenho inferior ao dos mais velhos. Na gravura: apenas o grupo de seis anos diferiu dos outros qrupos, não havendo diferença entre os sexos. Na comparação PLDK nível P e gravura, não foi encontrada nenhuma correlação significante. Tendo em vista a extensão da amostra, bem como a pouca informação científica sobre o desempenho no PLDK nível P, especialmente no Brasil, foi sugerida a realização de outras pesquisas. / The purposes of the present study were to investigate the influence of the dimension co1our in the emission of Tacts, face to pictures, and the vocabulary of preschool children. A group of forty-eight children of four, five, and six years old were the subjects during the research. In each age group the subjects were usually divided into two groups, the only difference being the order of presentation of coloured or black-white picture cards. The results in the PLDK indicate that : a)there were no significant differences in the performance , as a whole , face to colored or black-white cards ;. b) there were various significant correlations between achievement in each serie and the whole performance o The inter-series correlations however , were weak; c) further to the sequence of presentation , the results indicate that only the four years old group revealed better performance when the coloured set was presented showing the black-white one; d) regarding the sex variable, only once there was a difference between boys and girls e)considering the age variable, the younger children achieved a lower score than the older ones. The results collected after the presentation of the printed picture showed that the six years old group presented higher score when compared to the younger groups. The latter ones presented no differences among themselves. Considerering the variable sex, no difference was found. The scores particularly achieved by the presentation of the cards and printed picture were also compared and no significant correlation was found. Taking into consideration of the sample and lack of scientific information about performance in the PLDK Level P, mainly in Brazil, further research on the subject is suggested.
