MViewer: mobile phone spatiotemporal data viewer

Nowadays movement patterns and people’s behavioral models are needed for traffic engineers and city planners. These observations could be used to reason about mobility and its sustainability and to support decision makers with reliable information. The very same knowledge about human diaspora and behavior extracted from these data is also valuable to the urban planner, so as to localize new services, organize logistics systems and to detect changes as they occur in the movement behavior. Moreover, it is interesting to investigate movement in places like a shopping area or a working district either for commercial purposes or for improving the service quality. These kinds of tracking data are made available by wireless and mobile communication technologies. It is now possible to record and collect a large amount of mobile phone calls in a city. Technologies for object tracking have recently become affordable and reliable and hence we were able to collect mobile phone data from a city in China from January 1, 2008 to December 31, 2008. The large amount of phone call records from mobile operators can be considered as life mates and sensors of persons to inform howmany people are present in any given area and how many are entering or leaving. Each phone call record usually contains the caller and callee IDs, date and time, and the base station where the phone calls are made. As mobile phones are widely used in our daily life, many human behaviors can be revealed by analyzing mobile phone data. Through mobile phones, we can learn the information about locations, communications between mobile phone users during their daily lives. In this work, we propose a comprehensive visual analysis system named as MViewer, Mobile phone spatiotemporal data Viewer, which is the first system to visualize and analyze the population’smobility patterns from millions of phone call records. Our system consists of three major components: 1) visual analysis of user groups in a base station; 2) visual analysis of the mobility patterns on different user groups making phone calls in certain base stations; 3) visual analysis of handoff phone call records. Some well-established visualization techniques such as parallel coordinates and pixelbased representations have been integrated into our system. We also develop a novel visualization schemes, Voronoidiagram-based visual encoding to reveal the unique features of mobile phone data. We have applied our system to real mobile phone datasets that are kindly provided by our project partners and obtained some interesting findings regarding people’s mobility patterns.

Mobile phones as medical devices in mental disorder treatment: an overview

Mental disorders can have a significant, negative impact on sufferers’ lives, as well as on their friends and family, healthcare systems and other parts of society. Approximately 25 % of all people in Europe and the USA experience a mental disorder at least once in their lifetime. Currently, monitoring mental disorders relies on subjective clinical self-reporting rating scales, which were developed more than 50 years ago. In this paper, we discuss how mobile phones can support the treatment of mental disorders by (1) implementing human–computer interfaces to support therapy and (2) collecting relevant data from patients’ daily lives to monitor the current state and development of their mental disorders. Concerning the first point, we review various systems that utilize mobile phones for the treatment of mental disorders. We also evaluate how their core design features and dimensions can be applied in other, similar systems. Concerning the second point, we highlight the feasibility of using mobile phones to collect comprehensive data including voice data, motion and location information. Data mining methods are also reviewed and discussed. Based on the presented studies, we summarize advantages and drawbacks of the most promising mobile phone technologies for detecting mood disorders like depression or bipolar disorder. Finally, we discuss practical implementation details, legal issues and business models for the introduction of mobile phones as medical devices.     

Helpful-stressful cycle? Psychological links between type of mobile phone user and stress

The profusion of smartphones allows more people to have access to a telephone, a computer and the Internet, all via one device. Despite this convenience, excessive usage and habitual checking can cause significant stress for smartphone users. A helpful-stressful cycle is beginning to emerge as a pattern. With this in mind, we develop a model that examines the differences between smartphone and traditional mobile phone users with regard to the relationships between four psychological factors: locus of control (LOC), social interaction anxiety (SIA), need for touch (NFT) and materialism. Our examination explores this in the context of the level of stress these two types of users experience when using their chosen phone. The results from our empirical study suggest that user type moderates the aforementioned relationships. The effects of LOC, SIA and NFT on ‘technostress’ are stronger for smartphone users than for traditional mobile phone users. In contrast, materialism is positively related to stress for traditional mobile phone users but not for smartphone users.

Enacting new temporal boundaries: the role of mobile phones

This paper examines how the use of mobile phones influences the temporal boundaries that people enact in order to regulate and coordinate their work and non-work activities. We investigate both the structural and interpretive aspects of socio-temporal order, so as to gain a fuller appreciation of the changes induced by the use of mobile phones. With specific reference to professionals working in traditional, physically based and hierarchically structured organizations, we found that mobile phone users are becoming more vulnerable to organizational claims and that as a result ‘the office’ is always present as professionals, because of the use of mobile phones, become available ‘anytime’. This is enabled by the characteristics of the technology itself but also by users’ own behaviour. In the paper, we discuss the properties of the emerging socio-temporal order and show how mobile phones may render the management of the social spheres in which professionals participate more challenging.     

Worth-centred mobile phone design for older users

The twenty-first century society fights against an inherent tendency to over-classify and label people. In the case of the aged, despite all efforts, the perception of the helpless, feeble older person still prevails. The truth of the matter is that people over sixty often do not fit this profile. The aged are a heterogeneous group with varying different skills and abilities in many different areas. This paper challenges prevalent mobile phone design decisions that appear to have been made based on the erroneous pre-conception of the incapable elder. Designers currently produce “senior” mobile phones that are, at best, inadequate and, at worst, insulting to a sector of society that deserves respect and consideration. Age does indeed influence mobile phone usage, and people over sixty often have specific and special needs, quite apart from age-related limitations, that predict their use of mobile phones. Most mobile phones designed for older users simply reduce the number of features: the so-called simplification approach. Apart from reducing the effectiveness of the phone, this approach often incorporates the fatal design flaw of using numbers or letters, on speed-dial buttons, which requires the user to remember the button–person mappings. In fact, this design rationale reduces the value of the phone to the user. This paper argues that mobile phone design for older users should be worth-centred (Cockton G in Designing worth is worth designing. In: Proceedings of the 4th Nordic conference on human–computer interaction: changing roles. Oslo, Norway, pp 165–174, 2006) rather than simplification-driven. The worth-centred approach maximises worth to the user of the phone. This is achieved by maximising effectiveness while accommodating reduced capabilities. To maximise ease of use, and consequent accessibility, features may have to be reduced in an informed way. To facilitate this, a mapping process is proposed whereby user needs are linked to uses of the phone, and then to the features that facilitate these uses. Needs fall into a number of categories, and each category is characterised by a number of different uses, which form a usage space. Features can be linked to one or more usage spaces, and thus be used to support needs. The first step in the conducted research entailed the identification of the needs of the older mobile phone user. Then, it was determined whether these needs were indeed being met by the uses afforded in existing phones. Having concluded that most users’ needs were not being met, the next step was to capture data on the needs, limitations and expectations of people over the age of sixty. This was achieved by conducting a series of one-to-one interviews with a number of older mobile phone users and also supervising a participatory design experiment. Using the findings of the analysis, a usage space model is proposed, which serves to align feature inclusion with user needs. Based on this usage space model (the theoretical contribution), a prototype mobile phone design is presented as the practical contribution of the paper.
