Design reliable operating food ordering applications with UI/UX design : bachelor's thesis
Martina Arsovska, 2023, undergraduate thesis

Abstract: This bachelor's thesis illustrates the design process of two different food ordering mobile applications, ‘LUMA’ and ‘NIJA’. For the designing process we used ‘Figma’, a web-based interface design tool. It is also discussed the significance of UI/UX design and how it influences user engagement and satisfaction. In addition, we emphasized some of the applications key design components, such as logos, typography, colour palettes, as well as how we created and animated them. In this bachelor’s thesis we then reviewed the findings of the survey we conducted to collect input on the designs of the two applications.
Keywords: mobile applications, UI design, UX design, Figma, surveys

Mobile wallets' business models : refining strategic partnerships
Uschi Buchinger, Heritiana Ranaivoson, Pieter Ballon, 2015, original scientific article

Abstract: Background and Purpose: Though Mobile Wallets have the potential to entirely substitute their physical predecessor, many Mobile Wallets narrow their operations to one particular feature. This might be because of strategic business- model design choices to position themselves strategically as intermediates between users and business partners (third parties) in more delimited markets. Thus, Mobile Wallet Applications (MWAs) often represent platforms in narrow two-sided market structures. Design/Methodology/Approach: The paper focuses on the economics of such platforms by the means of a business model analysis. It examines how business partners are integrated in four MWAs’ strategies: Key Ring, FidMe, Apple Passbook and Qustomer. Results: The paper shows that MWAs strive to incorporate not only a large quantity of partners but also such with a high brand value (quality of partners) in their organization design. These partners shape their service design since none of the platforms offer products or services themselves. Hence, MWAs are dependent on the third parties’ capacity and willingness to fulfill engagements and meet the customer demands. Conclusion: MWAs - though concerned with the inclusion and management of loyalty points and schemes - do not leverage the possibility to generate revenue via third parties’ loyalty points. Theoretically, MWAs could reward or redeem loyalty points themselves.

An innovative approach to near-infrared spectroscopy using a standard mobile device and its clinical application in the real-time visualization of peripheral veins
Simon Jurič, Borut Žalik, 2014, original scientific article

Abstract: Background: Excessive venipunctures are a significant problem both in emergency rooms and during hospital stays. Near-infrared (NIR) illumination devices improve venipuncture success rate but their usage is limited by their availability and economic cost. The objectives of this study were to develop a low-cost NIR spectroscopy prototype from a standard mobile device, to evaluate its efficacy and acceptance as an educational tool, and in a clinical setting. Methods: Through a user-centric design process a prototype device was developed. Its educational efficacy was evaluated through a non-invasive, observational study (20 student clinicians, 25 subjects) and its acceptance was assessed using quantitative and qualitative analysis. A smaller clinical trial was performed by a group of 4 medical professionals over a period of 6 weeks that involved 64 patients. Results: The prototype enables real-time visualization of peripheral veins on a variety of Android-based devices. The prototype was 35.2% more successful in visualizing and locating veins (n = 500 attempts) than the nursing students. The acceptance assessment revealed high perception of usefulness, satisfaction, and ease of use. In the clinical trial, 1.6 (SD 1.3) additional veins per patient were identified compared with the traditional visualization methods. Conclusions: To the best of our knowledge this is the first study that describes the design, feasibility and application of an NIR spectroscopy prototype developed on a standard mobile device.
