A special thanks to Joshi for all the great support he has given me throughout my entire master project. Without your help, this thesis would most definitely not exist. Thanks also for always being available for guidance, even at inappropriate times like Sunday past 2am. I also want to thank everyone from the 9th floor a.k.a 9th grade. Thanks for all the great times playing the card game bullshit and our unnecessary long lunch breaks. They kept me going. Really. A special thanks also to Iben for helping me with proofreading. I want to particularly thank my girlfriend Aleksandra for supporting me through my insanity, helping with test facilitation, proofreading in the last writing stages and for letting me turn our living room into an electric skateboard workshop without complaining too much about it <3 I would also like to thank everyone who participated in my workshops, evaluated my prototypes and answered my survey. Thanks for all the great feedback and suggestions. In addition, of course, a big thanks to my family for being there for me and listening to my constant blabber about my thesis! Aleksander Rem, Oslo 16.11.2015. V VI Abstract This thesis examines how balance as input is used as a modality when controlling a personal mobility device. Through a user-centered design approach, we designed and built a fully functional mobility device prototype that uses balance as its only form of user input. We used an online survey for gathering needs and requirements, and created several design concepts and paper sketches through a focus group and design workshop. A balance controlled electric skateboard was chosen for further development, and iterated through paper prototyping. Two functional high-fidelity prototypes were constructed and tested in a formative and summative usability test with potential users. The prototypes were evaluated through a theoretical framework based on six aspects related to balance as input, which are: intuition, learnability, feedback, reusability, affordance and user experience (UX). The results showed that most of the participants found the final prototype intuitive. They showed progress during the test which indicates that a learning process occurred. The prototype gave the participants enough postural feedback, and those with a previous skateboard experience were able to use it when testing the electric skateboard, which indicates reusability. Even those that did not have previous experience were able to control the prototype after simple instructions, and every participant expressed how much fun they had using balance to control the prototype. To conclude, we have showed through our study that it is possible to use balance to control a personal mobility device in an intuitive way, and that the framework we proposed is a useful tool when evaluating balance as input.

A high quality, tailored, multimodal mobility eco-system, which includes the provision of sustainable first-mile / last-mile (FMLM) choices, integrating with long distance modes linking key centres, will be a key catalyst for the change required to maintain the region as a global competitor. ‘First-mile last-mile’ is typically used to describe the beginning or end of an individual journey to or from a transportation hub or service. Within the Heartland the definition of first-mile last-mile represents a wider choice of both traditional and emerging transport modes that enable access to opportunities and needs.

Valcea, Romania; [email protected] (A.C.); [email protected] (E.C.) 2 Faculty of Power Engineering, Politehnica University of Bucharest, Splaiul Independent, ei 313, P.O. 060042 Bucharest, Romania; [email protected] * Correspondence: [email protected] (A.C.); [email protected] (C.U.) Received: 3 September 2020; Accepted: 28 September 2020; Published: 30 September 2020 Abstract: This paper addresses the possibility of using an electric longboard in daily travel. A conventional longboard was transformed into an electric one and tested in ICSI Rm. Valcea labs. A series of tests were performed both at the laboratory level and, under normal running conditions, outdoors. Nevertheless, two possible scenarios have been taken into consideration. First, when the electric longboard is running on a flat road with a cruise speed, while the second scenario considered was that of climbing a hill with a 10% slope. The results confirmed the expectations and showed that a full charge of the batteries allows a trip over a distance of almost 50 km on a flat route having a consumption of about 10 Wh/km. However, there are some things to keep in mind when making travel distance predictions. The quality and the profile of the road, the weight of the rider, the rider position, all of these are factors which can significantly influence the predictions regarding the travel distance.
