The process of forest harvesting is highly mechanized in most industrialized countries, with felling and processing of trees performed by technologically advanced forestry machines. However, the maneuvering of the vehicles through the forest as well as the control of the on-board hydraulic boom crane is currently performed through continuous manual operation. This complicates the introduction of further incremental productivity improvements to the machines, as the operator becomes a bottleneck in the process. A suggested solution strategy is to enhance the production capacity by increasing the level of automation. At the same time, the working environment for the operator can be improved by a reduced workload, provided that the human-machine interaction is adapted to the new automated functionality. The objectives of this thesis are 1) to describe and analyze the current logging process and to locate areas of improvements that can be implemented in current machines, and 2) to investigate future methods and concepts that possibly require changes in work methods as well as in the machine design and technology. The thesis describes the development and integration of several algorithmic methods and the implementation of corresponding software solutions, adapted to the forestry machine context. Following data recording and analysis of the current work tasks of machine operators, trajectory planning and execution for a specific category of forwarder crane motions has been identified as an important first step for short term automation. Using the method of path-constrained trajectory planning, automated crane motions were demonstrated to potentially provide a substantial improvement from motions performed by experienced human operators. An extension of this method was developed to automate some selected motions even for existing sensorless machines. Evaluation suggests that this method is feasible for a reasonable deviation of initial conditions. Another important aspect of partial automation is the human-machine interaction. For this specific application a simple and intuitive interaction method for accessing automated crane motions was suggested, based on head tracking of the operator. A preliminary interaction model derived from user experiments yielded promising results for forming the basis of a target selection method, particularly when combined with some traded control strategy. Further, a modular software platform was implemented, integrating several important components into a framework for designing and testing future interaction concepts. Specifically, this system was used to investigate concepts of teleoperation and virtual environment feedback. Results from user tests show that visual information provided by a virtual environment can be advantageous compared to traditional video feedback with regards to both objective and subjective evaluation criteria.

Virtual Reality (VR) is a field within the gaming industry which has gained much popularity during the last few years. This is caused mainly by the release of the VR-headsets Oculus Rift [1] and HTC Vive [2] two years ago. As the field has grown from almost nothing in a short time there has not yet been much research done in all VR-related areas. One such area is performance comparisons of different interaction models independent of VR-hardware. This study compares the effectiveness of four software-based interaction models for a specific simple pick-and-place task. Two of the interaction models depend on the user moving a motion controller to touch a virtual object, one automatically picks them up on touch, the other requires a button press. The other two interaction models have the user move a laser pointer to point at an object to pick it up. The first has the laser pointer emitted from a motion controller and the second has it emitted from the user’s head. All four interaction models use the same hardware, the default HTC Vive equipment. The effectiveness is measured in three metrics, time to complete the task, number of errors made during the task, and the amount of participant enjoyment rated on a scale from one to five. The first two metrics are measured through an observational experiment where the application running the virtual environment also logs all relevant information. The user enjoyment is gathered through a questionnaire the participant answers during the experiment. These are the research questions: • How do the interaction models compare in terms of accuracy and time efficiency when completing basic pick and place tasks in this experiment? • Which interaction models are subjectively more enjoyable to use according to participants? The results of the experiment are displayed as charts in the results chapter and then further analysed in the analysis and discussion chapter. Possible sources of error and theories about why the results turned out the way they did are also discussed. The study concludes that the laser pointer based interaction models, 3 and 4, were much less accurate than the handheld interaction models, 1 and 2, in this experiment. All interaction models except 4 achieved about the same test duration while interaction model 4 lagged several seconds behind. The participants liked interaction model 1 the most, followed closely by 3. They disliked 4 the most and rated 2 at a point in the middle of the rest.

Seismic response of a structure is influenced by the inertial interaction between structure and deformable medium, on which the structure rests, due to flexibility and energy dissipation capability of the surrounding soil. The inertial interaction analyses can be performed by utilizing simplified soil-structure interaction (SSI) analyses methods. In literature, it is noted that varying soil conditions and foundation types can be modeled by using these SSI approaches with springdashpot couples having certain stiffness and damping. In this study, the seismic response of superstructure obtained by using simplified SSI methods is compared with those of the fixed base systems. For this purpose, single and multi degree of freedom structural systems are modeled with both spring&ndash / dashpot couple and fixed base models. Each system is analyzed for varying structural and soil stiffness conditions under the excitation of three different seismic records. Next, the total base shear acting on the structural system and internal forces of load bearing members are investigated to observe the inertial interaction and foundation uplift effects on the superstructure. It is also aimed to examine the compatibility of the simplified SSI approaches utilized in the analyses. It is concluded that the structural and soil stiffness parameters are the most influential parameters that affect seismic structural response. Structures becomemore sensitive to varying soil properties as the structural stiffness increases. On the other hand, decreasing soil stiffness also increases the sensitivity of the structure to the seismic excitation. Calculated values of total base shear and internal member forces revealed that the inertial interaction might be detrimental for the superstructure. Contrary to general belief, the fixed base approach does not always yield to the results, which are on the safe side. Considering the analysis results, it is concluded that SSI analysis is very useful for more precise and economical design for the seismic behavior.

For that the relationship between the show and its viewers was investigated. It is about understanding the object in its syncretic nature by approving the verbal, visual, and sound languages, both in content and expression plans - and according to entertainment and educative discourses, found in contemporary children's televised universe. The show consists of five seasons, among narratives and music clips, and presents a discursive construction based on linguistic syncretism for its apprehension modes: on one hand, the intelligible guided on theatrical performance, on the cognitive doing/knowing, on prescriptive duty and on volitional wanting; on the other hand, the sensitive, meaning these discourse procedures which explore the child s aesthesia competence through making it feel. It was thus identified that the program presents to its public sense effects ranging from the manipulating procedure based on intentionality and creation of the habit of watching Cocoricó, passing through programming, in regulating the being a child, faithful to the trademark and its different products, and to adjusting, in which the sense apprehension possibilities of this show are given in its own aesthesia qualities, as it makes sense to the child by means of aesthesia, that is, the reactive contagion. This study allowed us to introduce the TV Culture in its style of doing TV, as a social determiner: 1) in the formation of values: educative, ecological and being a paulista ; 2) of social behaviors ranging from the stereotype to social living and; 3) in the formation of the consumption taste of the trademark of the TV itself as well as its shows. Thus, what we have here in the relation between enunciator and enunciatee of Cocoricó is the child s identity formation, not only sociocultural but also forming the child to become a viewer, as it apprehends the meaning of whatever it sees on TV. The investigations and analysis proposals have followed the theorical-methodological outline of the Semiotics developed by Algirdas Julien Greimas, and the studies of Eric Landowski s with the Social Semiotics, especially the interaction methods / Esta pesquisa tem como objeto estudar os efeitos de sentido gerado pelo programa televisivo infantil Cocoricó, transmitido e produzido pela TV Cultura, investigando para isso, a relação construída entre o programa e seus telespectadores. Trata-se de compreender o objeto em sua natureza sincrética - pela homologação das linguagens verbais, visuais, sonoras, nos planos do conteúdo e expressão e segundo os discursos de entretenimento e educativo encontrados no universo televisivo infantil da contemporaneidade. O programa soma cinco temporadas, entre episódios e clipes musicais, e apresenta uma construção discursiva fundada no sincretismo de linguagens pelos seus modos de apreensão: por um lado, o inteligível pautado no fazer performático, no poder/ saber cognitivo, no dever prescritivo e num querer volitivo; e por outro lado, o sensível, quer dizer, esses procedimentos do discurso que exploram a competência estésica da criança pelo fazer sentir. Identificou-se, pois, que o programa propõe ao seu público determinados efeitos de sentido que perpassam as interações entre eles, pelo: a) procedimento da manipulação baseado na intencionalidade e na criação do hábito de assistir Cocoricó; b) procedimento da programaç~o, na regulaç~o do ser criança fiel { marca e aos seus diferentes produtos; c) procedimento do ajustamento, nas quais as possibilidades de apreensão do sentido desse programa televisivo são dadas em suas próprias qualidades estéticas, no fazer sentido para a criança por meio da estesia, ou seja, do contágio reativo. Este estudo possibilitou-nos apresentar a TV Cultura em seu estilo de fazer televisão, como destinadora social: na construção dos valores: educativo, ecológico e ser paulista; de comportamentos sociais que vão da estereotipia ao viver social e; na formação do gosto para o consumo da marca da própria TV e de seus programas. Tem-se, pois, na relação entre destinador-enunciador e destinatário-enunciatário de Cocoricó uma formação identitária da criança, tanto sociocultural, quanto uma formação para ser telespectador, no apreender o sentido do que se vê na televisão. As investigações e propostas de análises seguiram o arcabouço teórico-metodológico da Semiótica desenvolvida por Algirdas Julien Greimas e os estudos de Eric Landowski com a Sociossemiótica, em especial os procedimentos de interação
