“…Good user experience (UX) is desirable for both users and companies. For users, a delightful interaction experience not only fulfils their instrumental needs, but also non-instrumental ones such as beauty, satisfaction, and pleasure [2,3], while for companies, a delightful user experience is regarded as one of the key drivers of sustainability development [4,5]. Evidence shows that providing positive UX can increase user satisfaction and loyalty, thus promoting the commercial success of the company [6].…”

We introduce an approach that supports researchers and practitioners to determine the quality of first-time user experience (FTUX) and long-term user experience (LTUX), as well as to identify critical issues with these two types of UX. The product we chose to study is a mobile fitness application. Mobile apps tend to have a much shorter service life than most other products; thus, the developers/designers need to pay great attention to both first-time and long-term user experience. This study is based on a multi-method approach. We employed the AttrakDiff questionnaire to assess users’ first impressions of the app, and the UX Curve method to evaluate how users’ experience of the app has changed over time. Besides the quantitative data, which helped to determine the quality of user experience, we also collected qualitative data during two interviews with participants, and focused on the issues that predominantly deteriorated user experience. A four-coordinate plane tool was designed later in the data analysis process that combined the two kinds of user experience data at the same time, which led to a qualitative positioning of the user experience status of a certain product. The model was further successfully adopted in the identification of user experience issues of an online fitness application.

SINASense is a novel motion-based interface that serves as an educational application for children with severe or profound cognitive, sensory and physical impairments. The application makes use of computer vision to track the body movements of the user, which in turn trigger meaningful outcomes from the system. In this paper we describe the design principles of the interface, our experience during its evaluation, and finally we present ideas for future developments.

“…Head-trackers provide a hands-free way to interact with devices through the movements of the head and so, they have a direct application in assistive tools for motorimpaired users. In the assistive domain technologies, such interfaces are widely used for desktop computers [MYPVP10,MGiSLVG06] and in several commercial mobile applications [DSLKT03,GB].…”

We have developed an image-based head-tracker interface for mobile devices that uses the information of the front camera to detect and track the user's nose position and translate its movements into a pointing metaphor to the device. However, as already noted in the literature, the measurement errors of the motion tracking leads to a noticeable jittering of the perceived motion. To counterbalance this unpleasant and unwanted behavior, we have applied a Kalman filter to smooth the obtained positions. In this paper we focus on the effect that the use of a Kalman filter can have on the throughput of the interface. Throughput is the human performance measure proposed by the ISO 9241-411 for evaluating the efficiency and effectiveness of non-keyboard input devices. The softness and precision improvements that the Kalman filter infers in the tracking of the cursor are subjectively evident. However, its effects on the ISO's throughput have to be measured objectively to get an estimation of the benefits and drawbacks of applying a Kalman filter to a pointing device.
