abstract = {To enable automated testing of gesture-based applications, synthetic touch gestures must closely mimic real touch gestures. Although various generation methods exist, comparing them remains difficult due to the lack of standardized evaluation procedures. This work builds upon an existing initial evaluation framework that organizes relevant metrics into categories based on a taxonomy. We specify open aspects of the framework to support its practical and consistent application. We also propose a hierarchical structure for weighting and comparing metrics across categories. Finally, we outline how the framework can be extended to evaluate multi-stroke and multi-touch gestures.},

abstract = {Synthetic gestures are necessary for automating User Interface tests in applications using gestures, which often embed techniques from Artificial Intelligence and Machine Learning for gesture recognition. However, synthetic gestures must closely mimic the variances in human gestures. Therefore, algorithms capable of generating human-like fuzzy gestures depending on the configuration of user groups are necessary. In this paper, we analyze the differences between 2D and 3D gestures and correlate them with algorithms from Generative Artificial Intelligence designed for synthesizing gestures. Our findings support researchers and developers when developing components for gesture synthesis.},

abstract = {Electro-tactile interfaces are becoming increasingly popular due to their unique advantages, such as delivering fast and localised tactile response, thin and flexible form factors, and the potential to create novel tactile experiences. However, insights from a formative study with typical designers highlighted the lack of resources, limited access to information and complexity of software and hardware tools. This establishes a high barrier to entry and limits the ability to rapidly prototype and experiment with electro-tactile interfaces. To address these challenges, we propose eTactileKit, a scalable and accessible toolkit providing end-to-end support for designing and prototyping electro-tactile interfaces. eTactileKit comprises a hardware platform and a software framework for designing, simulating and exploring electro-tactile stimuli. We evaluated the impact and usability of eTactileKit through a three-week long take-home study, which demonstrated increased accessibility, ease of use, and the toolkit’s positive impact on design workflow. Additionally, we implemented a set of use cases to demonstrate the toolkit’s practicality and effectiveness across various applications.},

abstract = {With the rapidly growing number of articles published in the field of Human-Computer Interaction (HCI), it has become increasingly difficult to keep track of a given research area. Consequently, secondary research methods such as evidence synthesis are of growing importance. In this work, we transfer an evidence synthesis method from epidemiology to the field of HCI, develop a novel visualization technique specifically aimed at evidence synthesis, and make this technique available to the HCI community via the open source web application LayEv. To demonstrate how our approach can reveal new relational and causal paths between variables, we apply it to a set of publications identified in a prior literature review and visualize the results with LayEv. Future researchers can leverage our method to obtain comprehensive overviews of research areas, identify trends, and visualize existing evidence synthesis results.},

abstract = {We developed an Android phone unlock mechanism utilizing facial recognition and specific mimics to access a specially secured portion of the device, designed for plausible deniability. The widespread adoption of biometric authentication methods, such as fingerprint and facial recognition, has revolutionized mobile device security, offering enhanced protection against shoulder-surfing attacks and improving user convenience compared to traditional passwords. However, a downside is the potential for third-party coercion to unlock the device. While text-based authentication allows users to reveal a hidden system by entering a special password, this is challenging with face authentication. We evaluated our approach in a role-playing user study involving 50 participants, with one participant acting as the attacker and the other as the suspect. Suspects successfully accessed the secured area, mostly without detection. They further expressed interest in this feature on their personal phones. We also discuss open challenges and opportunities in implementing such authentication mechanisms.},

Consequently, we are entrusting more and more personal data to these devices, calling for strong security measures and authentication. However, the standard authentication method of such devices - entering PINs via virtual keyboards - is vulnerable to shoulder-surfing, as movements to enter keys can be monitored by an unnoticed observer. To address this, we evaluated masking techniques to obscure VR users' input during PIN authentication by diverting their hand movements. Through two experimental studies, we demonstrate that these methods increase users' security against shoulder-surfing attacks from observers without excessively impacting their experience and performance. With these discoveries, we aim to enhance the security of future VR authentication without disrupting the virtual experience or necessitating additional hardware or training of users.},
