Jian Yu is a 32 year old mechanical engineer from Germany (2). He graduated at the RWTH Aachen and lived in a small central apartment for a long time until he moved to Bonn for a new job that he is really happy to have (3). As Jian often helped friends with moving now they returned the favor (4). But beforehand, Jian thought a lot about how he could arrange his furniture (5). He wanted to have more space in each room now that he has more space available than before (6). He really hated the cramped look of his old apartment so he wanted something different (7). He also replaced some furniture but he kept most things as he also has some furniture pieces which he really loves and would not give up under any circumstances (8). Jian really likes modern, minimalistic furniture but also traditional pieces from Asia because his parents are Asian and took him to different countries when he was a kid (9). Jian still likes to travel but he also wants to keep the feeling of exotic experiences in his apartment which is why he has some special furniture (10). Planning the moving was really hard for him as available solutions did not really make him happy (11). The menu navigation in the app he chose was very complicated (12). In the end, Jian did not really like the room design when he saw it in real life so he rearranged stuff (13). He regretted it quickly because he moving damaged one of his beloved pieces (14). At that point he immediately stopped and started working with another app but this one was too cramped for him - it looked very fancy but did not provide good functionality (15). His main goal is to create room designs and try stuff out without actually moving his furniture too much (16). He prefers virtual solutions for desining but is unsatisfied with current tools (17). Not only would he need to have a virtual representation of his rooms but also of his furniture (18). He wants to keep certain pieces but would also like to buy new stuff which he needs to try out beforehand (19). He hates all the effort which seems to be necessary (20).
