“…The system uses the locations of these touch points to dynamically draw the grid of objects, and records pressure zones that are assigned to each finger. Fiorella et al [4] provided a preliminary study about multi-touch input (e.g., rotation, translation, and scaling) for 3D object manipulation on mobile devices. Their statistic analysis of 27 users on an iPod-touch device showed that their proposed multi-touch user interface could outperform the traditional button GUI.…”

Behavioral-biometric based authentication schemes on mobile phones usually begin by establishing a normal-behavioral model using machine learning classifiers and then identify behavioral anomalies through comparing current behavioral events with the established model. If an anomaly is detected, this kind of schemes will require the user for validation (i.e., input correct PIN). In this paper, we first propose a lightweight touch-dynamics-based user authentication scheme on a touchscreen mobile phone, which consists of only 8 touch-gesture related features. In addition, we further design an adaptive mechanism that can periodically select a better classifier to maintain the authentication accuracy during user authentication. As a study, we implement a cost-based metric that enables this mechanism to choose a less costly classifier. In the evaluation, the experimental results of involving 50 participants indicate that our proposed user authentication scheme can achieve an average error rate of 2.46% and that the adaptive mechanism can maintain the authentication accuracy at a relatively stable level.

“…Today's common solutions for interacting with VE with touch enabled devices mainly rely on multi-touch gestures or buttons to apply different camera transformations. It has already been shown that multi-touch gestures can surpass button based interactions [4]. When considering smartphones, multi-touch gestures imply that the user needs to hold the device with both hands, which can be tiresome and not always possible [1].…”

Three-dimensional virtual environments are present in many different applications, being used even in small handheld devices. To navigate in these environments using such devices, most of current solutions rely on multi-touch interactions. However, previous works have already stated that multi-touch gestures on smartphones are not always feasible. In this work we present ThumbCam, a novel single-touch technique for camera manipulation on 3D virtual environments. With our solution, the user is able to move and look around and circle points of interest, while interacting using only his thumb. We compare ThumbCam with other state-of-the-art techniques, showing that it can offer more operations with a single touch. A qualitative user evaluation revealed that users found our solution appealing.

The article presents software module designed for efficient and convenient visualization of 3D models inside the web browser environment. It is written purely in JavaScript and takes advantages of the new HTML 5 standard. The authors focus on mobile devices, so special attention is given on efficiency and low network usage. Proposed solution based on progressive mesh streaming is compared with server side rendering approach. The results of usability tests performed on real-life random users group will be discussed.
