Many driving scenarios involve correctly perceiving road elements in depth and manually responding as appropriate. Of late, augmented reality (AR) head-up displays (HUDs) have been explored to assist drivers in identifying road elements, by using a myriad of AR interface designs that include world-fixed graphics perceptually placed in the forward driving scene. Volumetric AR HUDs purportedly offer increased accuracy of distance perception through natural presentation of oculomotor cues as compared to traditional HUDs. In this article, the authors quantify participant performance matching virtual objects to real-world counterparts at egocentric distances of 7-12 meters while using both volumetric and fixed-focal plane AR HUDs. The authors found the volumetric HUD to be associated with faster and more accurate depth judgements at far distance, and that participants performed depth judgements more quickly as the experiment progressed. The authors observed no differences between the two displays in terms of reported simulator sickness or eye strain.

Most research on vehicle-to-vehicle (V2V) communication is technology-driven, or focused on driver-to-driver interaction. Social communication between drivers and passengers across vehicles, with the same destination, is often neglected. Communication is influenced by context and occupant behavior, and has a significant effect on the collaborative driving scenario. An exploratory in-situ study with seven groups of two driver/co-driver pairs each, located in two separate vehicles, was conducted. On a predefined route, different subtasks had to be solved in a collaborative way. The study revealed a significant influence of different social factors, such as driving behavior, and contextual factors such as weather conditions, or vehicle shape and size. Findings delivered important insights and a deeper understanding on collaborative driving that may influence future V2V communication technologies. Additionally, the collaborative driving behavior of the driver/co-driver pairs could be transferred to a multi-agent framework.

Two studies investigated the concept of following a lead vehicle as a navigational aid. The first video-based study (n=34) considered how drivers might use a real-world lead vehicle as a navigational aid, whist the second simulator-based study (n=22) explored how an Augmented Reality (AR) virtual car, presented on a head-up display (HUD), may aid navigation around a complex junction. Study 1 indicated that a lead vehicle is most valued as a navigation aid just before/during a required maneuver. During the second study the dynamic virtual car (which behaved like a real vehicle) resulted in greater confidence and lower workload than a static virtual car that “waits” at the correct junction exit, but resulted in more gaze concentration. It is concluded that a virtual car may be a valuable element of a navigation system, in combination with other forms of information, to completely fulfil all a driver's navigational task requirements.

Typified by the multi-touch interface in tablet, the paradigm for the human-computer interface of information technology (IT) devices has recently changed. Although many studies investigate determinants of adopting IT in the workplace, only a few of these studies acknowledge the motives behind IT adoption for personal use, particularly in an Arabian culture. Based on Theory of Reasoned Actions, this research model evaluates the influences of social norms and attitudes on the behavioral intention to adopt tablet computer by sample of college students in Kuwait. The model also examines three external determinants: attachment motivation, personal innovativeness, and perceived enjoyment. Further, we use structural equation modeling that provides a satisfactory explanation for 56% of the variance in the behavioral intentions to adopt tablets. The perceived enjoyment emerges as the strongest determinant followed by attitude, attachment motivation, and personal innovation. Unexpectedly, social norms have little influence on the behavioral intentions to adopt tablets.

Researchers recently demonstrated that subjective usability assessments of common products do not vary across geographic locations. That study did not directly address mobile applications, which are some of the most ubiquitous and geographically diverse systems in use in the United States today. To address this shortcoming, this article examined whether or not geographic location impacts the perceived usability of mobile applications by having 2,590 participants from different regions of the United States rate the usability of several mobile applications using the System Usability Scale. There was a lack of evidence to support statistically significant differences in usability scores across geographic locations for 95% of the mobile applications evaluated. This suggests that system usability assessments for mobile products do not differ across US locations. These findings further reinforce the idea that participants from any locale can be recruited for usability tests as long as all other critical demographic criteria are met.

Coproductions are reciprocal activities that all parties are actively engaged in and create synergies that cannot be produced by one party alone. Coproduction activities are important for community building, as the social interactions among community members create social values such as new social ties, trust and reciprocal recognition. Mobile technologies bring new opportunity for coproductions by supporting small-scale reciprocal activities that are location and time sensitive. In this article, the authors introduce and study WithShare, a smartphone application that helps people to organize such coproduction activities. A 3-week user study with 38 young adults in a local community of college students shows WithShare facilitates the coordination of opportunistic and lightweight reciprocal activities in their daily life. The results highlight potentials of coproduction activities in strengthening existing social ties, and establishing new weak ties in the local community. The findings suggest important design implications for mobile technologies to support coproduction activities.

In this article, the authors aim at finding a way to effectively communicate situations of risk related to work safety, by catching workers' attention without interrupting their main task. They designed a multimodal alarm solution specifically conceived for a biomedical lab, where workers might be intoxicated due to the possible leak of reagents or to excessive exposure to potentially toxic substances. The authors propose a novel multimodal alarm system which makes use of different sensory modalities, touch and vision. In particular, it exploits wearable technologies to improve the effectiveness of the alarm in the context. In details, it offers 1) tactile alarm to catch user attention, 2) different alarm modalities for collective and personal risks, 3) visual cue to provide immediate diagnostic information on the risk source, and more detailed information on the risk nature. In this article, the authors describe a pilot test in the real context of use to inform the design of the system. The results are promising for the development of the solution.

The social capital embedded within the social network relationships among users may facilitate their continued usage of mobile SNS. However, how to develop social capital remains a question. In this article, the authors incorporated three factors of system quality, information quality, and service quality from the information systems (IS) success model to examine their effects on social capital in mobile SNS. The results indicate that these three factors have significant effects on social capital, which includes structural capital, relational capital, and cognitive capital. The results imply that service providers need to improve users' technological perceptions in order to develop social capital and facilitate their continuance of mobile SNS.

Smartphones have become part and parcel of our daily life. Due to the more and more advanced features incorporated, its role has extended beyond calls and text messages, and it has become a place where important personal information is being stored. Thus, it needs to be protected from unauthorised users, which is usually achieved by using screen locking. However, improved screen locking security often compromises other aspects, such as usability and cost. In this article, a new screen locking method (SyS) that is both simple, secure from shoulder surf and smudge attacks, and not expensive to implement is presented. It uses an image and a chosen number to create the screen locking code. Evaluation results show that the SyS screen lock method scores best in terms of usability and security compared to the other three common screen locking methods, namely personal identification number or PIN, password, and pattern. It also performs well theoretically when compared against existing screen locking methods that aim at defending against similar attacks.

Post-adoption behavior has become one of the research hotspots in recent years. The purpose of this article is to research mobile search engine user's usage behaviour under the context of service harm crisis. Hypotheses and theoretical model are proposed by integrating expectation confirmation model of IS continuance, technology acceptance model, perceived risk theory, attribution theory and habit theory. The results indicated that continuance intention along with satisfaction and habit are important determinants of continuance behaviour. Perceived usefulness, perceived risk and continuance attitude have significant effect on continuance intention while attitude has the strongest effect. Confirmation promotes perceived usefulness, satisfaction and perceived ease of use which has an indirectly significant influence on satisfaction via perceived usefulness. Attribution of responsibilities has been found to have positive effect on perceived risk. Implications and contributions are provided.
