A KE-LSA approach for user-centered design

In today’s highly competitive business environment, most successful companies use ‘user-centered’ design techniques, to create products that meet user needs. Designers have used traditional user-centered design techniques, with some degree of success. However, in today’s market, companies need more accurate, more advanced user-centered design techniques, to mass produce customized products for individual users. This study introduces a new KE-LSA approach for user-centered design. Prior techniques used Kansei engineering (KE) for product design. Prior techniques used latent semantic analysis (LSA) for document indexing. The KE-LSA approach uses KE and a KE-LSA semantic space for individually customized product design. A case study is used to describe the KE-LSA approach. The case study uses the KE-LSA approach to match Kansei values for individual users’ needs to cell phone designs for each user. The case study also determines accuracy for matching KE-LSA designs to each user’s actual choice for a cell phone. In the case study, an iterative KE-LSA approach matched designs to users’ choices, with 82.3% overall accuracy. The iterative KE-LSA approach improved overall accuracy 11.4%, compared to a traditional iterative KE-QT1 approach. The KE-LSA approach improves matching accuracy for mass producing individually customized cell phone designs. Therefore, this study improves individually customized product design and product quality.     

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.

Mapping relationships between mobile phone call activity and regional function using self-organizing map

Mobile phone data help us to understand human activities. Researchers have investigated the characteristics and relationships of human activities and regional function using information from physical and virtual spaces. However, how to establish location mapping between spaces to explore the relationships between mobile phone call activity and regional function remains unclear. In this paper, we employ a self-organizing map (SOM) to map locations with 24-dimensional activity attributes and identify relationships between users' mobile phone call activities and regional functions. We apply mobile phone call data from Harbin, a city in northeast China, to build the location mapping relationships between user clusters of mobile phone call activity and points of interest (POI) composition in geographical space. The results indicate that for mobile phone call activities, mobile phone users are mapped to five locations that represent particular mobile phone call patterns. Regarding regional functions, we identified nine unique types of functional areas that are related to production, business, entertainment and education according to the patterns of users and POI proportions. We then explored the correlations between users and POIs for each type of area. The results of this research provide new insights into the relationships between human activity and regional functions.     

Diversified users’ satisfaction with advanced mobile phone features

Mobile phones are widely used all over the world, and with their increasing number of value-added features, they are becoming far more than a mere mobile voice communication device. Rather, they provide a powerful platform for accessing information universally. This paper reports a study which scrutinized users’ preference levels with five new mobile phone design features facilitating universal information access through mobile phones: camera, colour screen, voice-activated dialling, Internet browsing, and wireless connectivity (e.g. Bluetooth, infrared, etc.). The survey study involved college students and investigated the degree to which each of the above features impacts the users’ overall satisfaction and enhances the potential of mobile phones to contribute to different aspects of universal access. Our results show that colour screen, voice-activated dialling, and Internet browsing feature can strongly predict users’ satisfaction level, and their preference levels together account for 22.7% of the variance of the users’ overall satisfaction. Users’ satisfaction levels are significantly different between models with colour screen feature and those without, and models with Internet browsing features and those without. Since mobile phone design needs to accommodate the needs and preferences of diversified user groups, the performed study also investigated the difference in users’ preference levels of the five new features for different ethnic groups, and difference in mobile phone owned by different genders. The result indicates that Asian female users in the U.S. market have higher preference level on colour screen feature than Caucasian female users. Significantly higher percentage of male users own phones with camera, Internet browsing, and wireless connectivity features than female users. The empirical study reported in this paper provides a comprehensive picture of how new design features can enhance the mobile phone as a universal access device, and what impact they have brought about. It can also help manufacturers adopt a universal design perspective in view of the differences in preference levels of users with different ethnicity and genders.     

Kei-Tying teens: Using mobile phone e-mail to bond, bridge, and break with social ties—a study of Japanese adolescents

This paper examines the extent to which Japanese adolescents use mobile phone e-mail to bond, bridge, and break with their social ties. Although existing literature shows that adolescents use mobile phone e-mail to bond with intimate strong ties, the fluid nature of social networks during adolescence suggests that mobile phone e-mail may also be used to bridge to new ties and to break with old ties. Drawing on a stratified random sample survey of 501 high school students living in Tokyo, we find that mobile phone e-mail is used both to bond and bridge, but not to break with ties. We also find that the intensity with which Japanese adolescents use mobile phone e-mail is more fundamentally a result of bridging than bonding. These findings apply both to typical users and heavy users.     

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.
