Tool in a Box : How should a website for renting tools be implemented to benavigable and be perceived as usable?

Abstract: Today, when university students move into a new apartment they seldom have the neededtools to complete the tasks, such as putting up a shelf, related to the occupancy. Thereexist few services that rent these tools in a smooth and simple manner, which leads thesestudents to purchase new tools. Therefore the study has created a web application torent these tools from parcel lockers. The purpose of this study is to research the impact ofdifferent variables on usability and navigability using the aforementioned web application.To this end, a web application was designed and produced as a basis for the tests conducted in this study. To measure the impact of these variables the tests used metricssuch as lostness and the system usability scale together with methods including CTA andretrospective probing. After the tests had been performed using the web application thestudy could conclude that it is of paramount importance for critical information to bedisplayed in relevant and easy-to-find places. It was also concluded that the display ofinformation should be done in as simple of a manner as possible to maximize user information retention. It was also found that smaller changes such as allowing users to submituser credentials using the return key do not substantially increase the perceived usability.However, it was concluded that such features are perceived as an obvious features anddecrease the perceived usability of the website when not present. The study also observedthe importance of continuous user testing, as it revealed many aspects that could otherwisebe difficult to spot.
