New technologies are constantly introduced in our everyday life. Societies and people have reaped great benefits from integrating information technology into a plethora of societal and commercial functions. However, innovations are not unconditionally accepted by users. Since digital innovations constantly are introduced to aid us, there is an interest in understanding what factors would either influence us or make us prone to adopt new technologies. The main research question is to identify the key influences, both positive and negative, within technology adoption. The scope was limited to Scandinavian supermarkets and the technology of adoption intention was the Smart Cart; a seamless approach to make your shopping experience easier. Through a value-based acceptance model (VAM), a quantitative survey was conducted to explore consumers, attitudes towards Smart Cart through the factors perceived usefulness (PU), perceived enjoyment (PE), perceived privacy risk (PPR) and perceived difficulty to use (PDU), in relation to the perceived value (PV) of the product which can eventually lead to intention to adopt and use(IAU). The findings showed that perceived usefulness (PU) and perceived enjoyment (PE) demonstrated a strong positive correlation to potential users’ perceived value (PV) of Smart Cart while perceived privacy risk (PPR) showed a weak negative and perceived difficulty to use (PDU) showed a medium-strong positive correlation to potential consumers’ perceived value (PV) of the product. Potential consumers’ perception of Smart Cart’s value (PV) showed a strong positive correlation with intention to adopt and use (IAU).

I dagens samhälle blir många saker smartare, främst med hjälp av Internet of Things.En överblick på smart shopping visar att flera alternativa sätt att shoppa på harintroducerats under de senaste åren för att förbättra och effektivisera shopping. Någraav dessa är online-shopping och självtjänster som inkluderar självutcheckningar ochhandhållna skannrar. Detta har varit ett framgångsrikt tillvägagångssätt, vilket kanses av det faktum att en av de största dagligvaruhandelskedjorna i Sverige, ICA, har1,5 miljoner kunder i sitt lojalitetsprogram där cirka 30% av dessa använderhandhållna skannrar. Dessa 30% ger cirka 60% av ICAs totala intäkter i några avderas största butiker. En av de stora utmaningarna med självbetjäning är dock att deär mycket dyrt, då ett system för en genomsnittlig butik i Sverige kan kosta cirka 1,5miljoner SEK. Detta gör det svårt för mindre butiker att erbjuda denna tjänst. Ett sättatt överkomma detta kan vara att skapa en applikation för smartphone-shopping(Smart Cart-app) med en användarcentrerad design, som med största sannolikhetsänker kostnader samt sparar tid. Tidigare forskning har visat försök på liknandeteknologies, men vissa av dessa hade begränsningar i presentationen av sin design ochanvändardata/användarforskning. Denna studie syftar till att undersöka möjlighetenatt utforma en Smart Cart-applikationsprototyp med en användarcentrerad designbaserad på Human-Computer Interaction (HCI) för att utvidga på tidigare förslag.Användardata, som har analyserats för att hitta viktiga punkter och önskemål idesign, har samlats in genom ett frågeformulär med 275 deltagare och intervjuer med3 personer. Denna data har använts tillsammans med information från enlitteraturöversikt för att utforma prototypen för Smart Cart-appen, som är envisualisering av studieresultaten. Prototypen stöds av en analys som visar varför det ärviktigt att involvera användare i designprocessen och vad som bör beaktas när mangör detta. Studien fann också en begäran efter en sådan app, då exempelvis 51,7% avsjälvscannande kunder skulle överväga att använda den. Dessutom stöder resultatenockså det faktum att om användaren accepterar och har en bekantskap med vissafunktioner i applikationen, är de mer benägna till att ta an applikationen. Majoritetenav deltagarna har en positiv inställning till applikationer inom smart shopping och harliknande önskemål om funktioner och utseende.Slutligen behövs framtida forskning om olika aspekter och synpunkter förvidareutveckling av Smart Cart-applikationen och andra liknande applikationer / In today's society, many things are becoming smarter, mostly with the help of theInternet of Things. Taking a look at smart shopping, several optional ways of shoppinghave been introduced in recent years to enhance and streamline shopping. Some ofthese are online shopping and self-services which include self-checkouts and handheldscanners. This has been a successful approach, which can be seen by the fact that oneof the biggest grocery shopping chains in Sweden called ICA has 1.5 million customersin their loyalty program where around 30% of these use handheld scanners. These30% bring about 60% of ICAs total revenue in some of their biggest stores. However,one of the major challenges with self-services is that they are very expensive, as asystem for an average sized store in Sweden can cost around 1.5 million SEK, whichmakes it difficult for smaller stores to offer this service. A way of combating this couldbe to create a smartphone shopping application (Smart Cart app) with a user-centereddesign, which has a strong likelihood to lower the costs as well as save time. Previousresearch has shown attempts of similar technologies, however, some of these hadlimitations in the presentation of their design and user research. This study aims toexplore the possibility of designing a Smart Cart application prototype with auser-centered approach based on Human-Computer Interaction (HCI) to extend uponprevious proposals.User data, which has been analyzed to find key points in design, has been gathered bya questionnaire with 275 participants and interviews with 3 people. This data has beenused together with information from a literature review in order to design the SmartCart app prototype, which is a visualisation of the study results. The prototype issupported by an analysis which shows why it is important to involve users in thedesign process and what should be considered when doing so. The study also found adesire for such an app as, for instance, 51.7% of self-scanning customers wouldconsider using it. In addition, results also support that when users accept and arefamiliar with certain functionalities in applications, they are more likely to adopt theapplication. The majority of the participants have a positive attitude towardsapplications in smart shopping and have similar desires of functions and appearance.Lastly, future research is needed on different aspects and point of views for furtherdevelopment of the Smart Cart application and other similar applications.
