Data visualisation can provide a user-friendly way to observe and understand data. It can make is easier to make well-informed decision and communicate findings in data. This study aims to research how to effectively structure and visualize a complex data sets in order to improve a battery discharge process. By implementing a dashboard and visualising a data set from electrical battery discharging, the following objectives are considered; analyse and identify which parameters and variables are most important in the battery discharging process. Analyse how data transformation and cleaning can support data visualisations. Define an interface that visualises the trends, anomalies and correlations of the data set. Evaluate how the visual representation is perceived by users in the battery recycling process?The study followed the User Centered Design method, which consist of five phases that are iterated. During the phases Identify needs and Specify context of use six stake holder interviews was held, theses were analysed through an Affinity diagram and Personas. In the phase Specify requirements requirements are established by conducting a user journey mapping. The data and insights from the previous phases was turned into ideas and solutions in the phase Produce design solutions. In total three low-fidelity and one high-fidelity prototype were created, as well as one implemented solution. In the last phase Evaluate design the design solutions were tested though, interviews, usability test and a survey. The result of the study strengthens the theory that data visualisations can be used to provide insights. The findings show that visualisation to some extent could help detect abnormalities, patterns and correlation between variables, which could be useful in improving a process.

Reading old handwritten documents can be a real challenge for genealogists, especially as some documents in Sweden are written in the old German alphabet that is not used today. Much research has been done on how to enable computers to read old handwritten documents, but computers have so far not reached the level of reading that expert humans have. The focus seems to be on the computers reading the document with or without the help of human experts, with the aim of making the documents available in easily read form. I have, however, not found any research on how computers can help non-expert humans trying to read handwritten documents. In this project I have focused especially on beginning genealogists as reading gets easier with practice, and you need the help more in the beginning.By conducting interviews and observations with genealogists I established that reading is an issue and that there are many factors involved that make it difficult to read. Among the factors that make it difficult to read are handwriting, foreign alphabet, unknown words and old-fashioned spelling. I designed hi-fi prototypes that combine elements of online crossword-lexicons, encyclopedias and a visualization of the word in the German alphabet. After testing these on genealogists I could conclude that the prototypes made it possible for test subjects to identify words that they could not otherwise read. Seeing suggestions of words in the same alphabet as the source word makes it easier to identify the correct word. The prototypes and test texts contained a very limited amount of words and further research is needed concerning how to order and choose among word matches in a large lexicon to facilitate finding the correct word.

Smart clothing is far from being adopted by regular consumers and worn on a regular basis. Most developments can be found in specialized markets and all of the few consumer products so far have not been commercially successful. The first part of this thesis illustrates why this is the case and presents a few examples of concepts that show the potential of smart clothing in an everyday context.The second part shows my own practical research into the subject and the resulting design concept. It follows a user-centered design process with participatory design elements and ends in a concept proposing clothing that can change color and style on the go. The concept tries to support a sustainable lifestyle by slowing down fast fashion and democratizing fashion design. It makes it easy for the wearer to create her own styles and to change the style on the go to adjust to different situations or different moods. The end result of this thesis is a prototype that serves as a proof-of-concept.
