To measure physical activity in a wheelchair user is important. Disabled people have been found to be less active and it has negative health implications. By relating to ones own physical activity in concrete form it is easier to reinforce a positive attitude towards being physically active. The aim of this thesis is to show how a system can be built, that is able to collect measurements from sensors, with usability in mind. The system consists of software that integrates an iPhone, Apple Watch and a Tacx rotation sensor mounted on a wheelchair. With the help of a physics model these measurements can estimate energy expenditure of a wheelchair user. The system was tested with four participants performing subjectively decided low, moderate and vigorous physical activity while the system collected data. In terms of absolute energy expenditure the system was inaccurate. On the other hand, correlations were found between the calculated energy expenditures and physical activity. Using measurements from the rotations sensor a correlation of 0.7315 was found between the calculated energy expenditure and physical activity, a correlation of 0.5385 using measurements from the GPS and a correlation of 0.6452 using measurements from Apples own proprietary algorithm. The created system is a promising prototype towards objective measurement of physical activity in wheelchair users.

The market for wearable devices is continuously growing and has seen an in- crease in interest and demand this past year, specifically smartwatch devices. With several big players entering and trying to take place in the market the number of devices and platforms grow. This leads to device and software fragmentation like the one seen in the world of smartphones. In this paper I discuss and compare the two smartwatch platforms Android Wear and Apple Watch in terms of possibilities, limitations and differences. Research is done to find cross-platform development possibilities for these platforms. Extensive theoretical background of both APIs is researched and presented. An app for both smartwatch platforms is developed with integration of the WebSocket protocol to function as a remote control for a Video-On-Demand web service. This is done to showcase the cross-platform possibilities and differences of the platforms. As a result the biggest differences are out- lined and a conclusion is made that cross-platform development for these platforms can be challenging but is possible on certain levels.

Wearable technology has many potential benefits for employees in the workplace, including safety, health, and motivation. However, there are also many concerns about privacy and the use of data from these devices. More research is needed to understand how privacy affects the user acceptance of wearables in the workplace. The purpose of this thesis is to understand how users perceive and accept wearables at work from a privacy perspective. The thesis studied wearable fitness trackers and evaluated the acceptance of these based on an extended version of the technology acceptance model (TAM). The thesis performed qualitative interviews with users who use wearables daily and presents the largest factors identified to influence the acceptance of wearable fitness trackers at work from a privacy context. The result of the research shows that there are three main factors influencing the acceptance of wearables in the workplace from a privacy perspective: User’s privacy and data disposition, the importance of transparency, and the importance of aligned subjective norms.

The presence of smart wearables has established itself as a norm of the 21 st century, but the state of their trustworthiness from the viewpoint of personal safety remains debatable. The information gathered by such devices has great potential for personal safety risks and must be handled safely. Previous work on the Garmin Venu watch gave room for relevant future work. This thesis aims to perform further evaluation of this smartwatch in unexplored areas. The work took inspiration from the relatively new “PatrIoT” penetration testing methodology, developed in-house at the Network and Systems Engineering lab, customized for penetration testing of Internet of Things devices. This project examined a broad surface on the watch including network traffic, data over USB connection, a few details in the watch’s update mechanism, probed for some memory attack mitigations, fuzz testing of some functions in the Software Development Kit’s Application Programming Interface, and some more. According to these investigations, the watch is perceived as safe. A deeper look into some investigations is left for future work. / Bärbara enheter har blivit en normal del av 21:a århundradet, men deras pålitlighet från ett personligt säkerhetssynvinkel är diskutabelt. Informationen som samlas in av dessa har stort potential för att orsaka personliga säkerhetsrisker och måste hanteras säkert. Tidigare utförda undersökningar av Garmin Venu-smartklockan lämnade utrymme för relevant framtida arbete. Det här examensarbetet siktar på att utföra ytterligare undersökningar av denna smartklocka. Arbetet tog inspiration av det relativt nya “PatrIoT” intrångstestmetodologin, internt utvecklad av personalen i avdelningen för nätverk och systemteknik, skräddarsydd för intrångstestning av Sakernas Internet-enheter. Det här projektet undersökte en bred attackyta på klockan, inkluderande datatrafik, data över USB-anslutning, några detaljer i klockans uppdateringsmekanism, undersökte närvaron av några mekanismer för minnesbaserade attacker, försök till störningsattacker i programvaruutvecklingssatsens applikationsprogrammeringsgränssnitt, med flera. Enligt dessa undersökningar uppfattas klockan vara säker. En djupare undersökning av dessa aspekter lämnas till framtida arbete.

New technology is revolutionizing the retail industry by providing new conditions and questioning the traditional way of shopping. Wearable devices have gained popularity lately and smartwatches are one of the most popular among them [12]. However, little research has been made in the area of creating experiences for grocery retail purchases using smartwatches, which is where this study aims to contribute. Through establishing what affordances and challenges there might be when creating a digital experience for people using smart watches with the intent of purchasing groceries. With the support from CompanyX, one of the leading companies with their core business in grocery retail, the study was built around Apple Watch users as the target group. An experience-centered design method was used to incorporate the end user at each stage of the design process. A high fidelity prototype was created based on the decoded material from the semi-structured interviews performed. The prototype was then evaluated in a remote setup using both in-depth test sessions and a broader evaluation questionnaire. The results showed that the prototype proposed added value for the user by providing an experience that would encourage a more structured and inspirational way of purchasing groceries. The attitude towards the prototype was positive. However, further improvements are suggested and discussed aiming to suit the limited interaction options of a smartwatch, better. The study provides insights in what the attitude looks towards different types of functionalities aiming to create an enhanced grocery shopping experience among Apple Watch users. / Nya tekniska förutsättningar revolutionerar handelsmarknaden genom nya förutsättningar som ifrågasätter traditionellt sätt att handla på. Teknologier som Wearables har under de senaste åren blivit mycket populära där de vristburna enheterna är de som står ut särskilt i popularitet. Dock har lite studier gjorts på hur man med hjälp av Wearables skulle kunna skapa en upplevelse ämnad att underlätta shoppingupplevelsen hos personer som handlar matvaror. Vad öppnar en smartklocka upp för förutsättningar och vad finns det för utmaningar att skapa en upplevelse med hjälp av en smartklocka? Med stöd från CompanyX, en av Sveriges ledande företag inom dagligvaruhandel, byggdes studien kring Apple Watch-användare. Användaren var central genom hela studien då den var byggt runt användarbeteenden och användarupplevelser. En prototyp skapades baserat på de resultat som fastställdes kring användandet, samt testad på slutanvändarna. Resultaten visade att prototypen skapade värde för användaren då den uppmuntrade till ett mer strukturerat samt inspirerande sätt att handla matvaror på. Prototypen togs emot positivt men skulle gynnas av ytterligare förbättringar och design iterationer främst kring smartklockans begränsade interaktionsmöjligheter. Studien bidrar med insikter kring hur attityden ser ut kring skapandet av en användarupplevelse för matvaruhandel i en smartklocka hos Apple Watch användare.

The ankle joint complex is a common source of injury for various demographics and is often observed during gait analysis. I investigate using soft robotic sensors as a means for collecting kinematic data at the ankle joint complex. I validate the linearity of these sensors by measuring stretch against extension and against stretch from frontal and sagittal planar foot movements using a wooden ankle mockup. I then conduct a study involving ten participants who perform repetitive trials of four foot movements (plantarflexion, dorsiflexion, inversion and eversion) using ten different locations. Four optimal locations were identified for these movements based on linearity, accuracy, robustness, and consistency. Lastly, I validated soft robotic sensors against the human gait cycle. Twenty participants were recruited and performed twelve trials, walking across a flat surface and a cross-sloped surface while motion capture data and soft robotic sensor data was collected.

The complex process of patient placement within a hospital is a big challenge. The main focus in the process is how to coordinate clinics to make sure that the patients get the best possible care. The rise of digital health has led to a greater use of technologies to facilitate the activities within the hospitals’ processes. This study has been focusing on how Internet of Things can be used in the patient placement process. Respondents to participate in the interviews were chosen with help from a coordinator based on their experience within the study area of interest. Observations were done in meetings where the staff discussed patient placements. From a perspective of problem based coordination, a thematic analysis was done on the collected data and from the themes that were created a solution was presented. The object of this study is to map the process of patient placement and to present an analytic approach on how to facilitate the patient placement process with the use of Internet of Things. Our proposed approach will contribute to a greater understanding of the patient placement process and how Internet of Things can be used within it.
