Mobile phones are transformed into smart phones and their capabilities are enhanced far beyond the level of a phone (Reynolds, 2008). The number of smart phone users can be estimated from the number of smart phone shipments in 2012. According to Canalyse, 694.8 million units of smart phones were produced in 2012 (Canalyse, 2013). Another figure of smart phone shipments in 2012 quoted by IDC, is 722.4 million units (IDC, 2013). Smart Phone market is continuously progressing. These figures are representative of the popularity and acceptance of smart phones in the masses. There is no doubt that this popularity and acceptance is due to the unique features provided by smart phones. Among others, one of the unique features of smart phone is web browser with fairly improved capabilities (Reynolds, 2008). Its usefulness and popularity can be estimated from the statistics presented by comScore (2011), that in Japan, US and Europe people spend 55.4%, 36.4% and 28.8% of time (out of total phone usage time) by using mobile browsers. The growing trend of browsing through smart phone browsers attracted the interest of software developer community, and now dozens of commercial and open source browsers are available in market. Web browsing using smartphones has become one of the most common use among the use of other applications. Figures show that web browsing using mobiles phones has increased from 9.58% to 25% in last two years (StatCounter, 2013). This increasing trend can be credited to several factors such as better supporting infrastructure and services e.g. Wi-Fi, 3G, 4G, etc. and availability of sophisticated smartphones and web browsers with fairly improved capabilities (Reynolds, 2008). Different companies shipped around 1 billion mobile phones in 2013 and 55.1% of them were smartphones (IDC, 2014). Experts forecasted that the growth of smartphone market will progress and would reach 1095 million in 2016 (Portio, 2013). Smartphone has revolutionized the idea of web browsing with its web browsers. Smartphone browsers are not only used for information seeking tasks but for other purposes also such as shopping. It is reported in ‘‘Smartphones Leading to Greater Transparency in the Shopping Experience’’ (2011), that over 70% of iPhone owners use applications or web browsers while shopping in store and 41% make purchases directly from their phone. These trends compelled many researchers to work on smartphone related issues. Several studies have been conducted on usability and usage of smartphone. In this paper, the usage pattern related to smartphone web browsers are identified with respect to different age and experience groups. The results of this study will help to better understand the usage of smartphone browsers and will help the practitioners to improve browsers for better usability. http://dx.doi.org/10.1016/j.chb.2014.10.054 0747-5632/Ó 2014 Elsevier Ltd.

1. Introduction

The advancement in communication technologies has reshapedthe idea of mobile phone. Mobile phones are transformed intosmart phones and their capabilities are enhanced far beyond thelevel of a phone (Reynolds, 2008). The number of smart phoneusers can be estimated from the number of smart phone shipmentsin 2012. According to Canalyse, 694.8 million units of smart phoneswere produced in 2012 (Canalyse, 2013). Another figure of smartphone shipments in 2012 quoted by IDC, is 722.4 million units(IDC, 2013). Smart Phone market is continuously progressing.These figures are representative of the popularity and acceptanceof smart phones in the masses. There is no doubt that thispopularity and acceptance is due to the unique features providedby smart phones.

Among others, one of the unique features of smart phone is webbrowser with fairly improved capabilities (Reynolds, 2008). Itsusefulness and popularity can be estimated from the statisticspresented by comScore (2011), that in Japan, US and Europe peoplespend 55.4%, 36.4% and 28.8% of time (out of total phone usagetime) by using mobile browsers. The growing trend of browsingthrough smart phone browsers attracted the interest of softwaredeveloper community, and now dozens of commercial and opensource browsers are available in market.

Web browsing using smartphones has become one of the mostcommon use among the use of other applications. Figures showthat web browsing using mobiles phones has increased from9.58% to 25% in last two years (StatCounter, 2013). This increasingtrend can be credited to several factors such as better supportinginfrastructure and services e.g. Wi-Fi, 3G, 4G, etc. and availabilityof sophisticated smartphones and web browsers with fairlyimproved capabilities (Reynolds, 2008). Different companiesshipped around 1 billion mobile phones in 2013 and 55.1% of themwere smartphones (IDC, 2014). Experts forecasted that the growthof smartphone market will progress and would reach 1095 millionin 2016 (Portio, 2013). Smartphone has revolutionized the idea ofweb browsing with its web browsers. Smartphone browsers arenot only used for information seeking tasks but for other purposesalso such as shopping. It is reported in ‘‘Smartphones Leading toGreater Transparency in the Shopping Experience’’ (2011), thatover 70% of iPhone owners use applications or web browsers whileshopping in store and 41% make purchases directly from theirphone. These trends compelled many researchers to work onsmartphone related issues. Several studies have been conductedon usability and usage of smartphone. In this paper, the usagepattern related to smartphone web browsers are identified withrespect to different age and experience groups. The results of thisstudy will help to better understand the usage of smartphonebrowsers and will help the practitioners to improve browsers forbetter usability.

The paper is organized as follows: related works are discussedin Section 2. Research methods and information about therespondents are presented in Section 3. Findings of the study arepresented in Section 4 and discussed in Section 5.

2. Related works

The usage of smartphone has been discussed in many studies.These studies include those where the usage of smartphone is dis-cussed including its entire features and in some studies specificapplications were focused. A few of notable works are presentedhere. A survey was conducted in Bomhold (2013), with undergrad-uate students to know use of smartphone applications. The resultsof this study show that using search engine is the most frequenttask performed by the users. Another study (Lin, Zhang, Jung, &Kim, 2013), was conducted to know the extent wireless communi-cation has affected the traditional wired means. A survey was con-ducted; involving youth between 12 to 17 years of age in five EastAsian cities. The authors have identified three main categories ofmobile internet usage namely; task based activities, informationseeking and communication activities, and recreational activities.The study concluded that teens tend to use their mobile internetfor recreational and entertainment purposes. The social mediapractices of smartphone users were outlined in Malinen andOjala (2012). Qualitative research method; interview was usedand 30 owners of smartphone were interviewed. The results of thisstudy suggest that users of mobile social networking applicationsmostly check the news and latest updates while on the move. Sec-ondly, it was observed that there were more browsing activities onmobile phones than content creation.

The security of smartphone browsers is discussed in Mylonas,Tsalis, and Gritzalis (2013), from the view point of availabilityand manageability of security controls. Analysis of security controlis conducted and recommendations are provided. A study on thetrends of smartphone usage was conducted in Osman, ZawawiTalib, Sanusi, Yen, and Alwi (2011) focusing Malaysian market formobile content and applications. The results were based on a sur-vey conducted in different cities. The results show that 23.26% ofthe population used smartphones daily to brows web pages,18.38% used a few times weekly and 11.10% used weekly to browsweb pages. The lessons learned from a four month field study arepresented in Rahmati and Lin (2013), which include applicationusage and usage characteristics of 14 participants (novice teenageusers). The results show that the participants used the smart-phones in highly mobile fashion and usage was location depen-dent. Other results include session length, usage length, andnumber of sessions per hour. It took five to six weeks for partici-pants’ usage to stabilize.

A study (Shirazi, Henze, Dingler, Kunze, & Schmidt, 2013) wasconducted to investigate that how smartphone applications, inparticular web browsers are used. The data about the posture ofdevice show that phones were moved more while messaging andusing navigation applications. In case of browser and other applica-tions less movements were observed. Regarding the use of multi-ple browsers, 31% of the participants used more than onebrowser. The participants tend to use browser for a longer periodof time when open it through system launcher rather opening itthrough other applications. High rate of switching between appli-cations and browser is observed during the study. The averagelength of session was 2.36 min and when started through anotherapplication it was 1.52 min.

A Delphi method study was conducted in Dunn, Galletta,Hypolite, Puri, and Raghuwanshi (2013) by engaging the Smart-phone users and potential users. Three task lists are presented asthe result of the study; one for smart phone users, all users, and

non-users of smart phones. Following four tasks were part of thetask list of smart phone users; check email, send email, internetsearch, browse internet. These tasks are related to the use ofbrowsers. Although the research presented in this paper is similarinto this study as both of the studies aim to identify user task.However, the methodology and scope differs, in this paper qualita-tive method; interview is used to identify the tasks. Furthermore,the scope of our study is limited to the smart phone users and par-ticularly the users of smart phone browsers.

A study (Oulasvirta, Rattenbury, Ma, & Raita, 2012) on smart-phone users habits concluded that brief usage sessions comprisea large part of smartphone usage. While comparing smartphoneand laptop it was found that smartphone use is significantly shortin duration. It was also found that the smartphone use habits aretightly associated with particular context.

In one of our previous work (Fazal-e-Amin and Alghamdi,2014), a usability evaluation model is presented to evaluate theusability of web browser. This model presents the attributes andsub attributes of usability in three layers. Usability tests were con-ducted with participants on four android web browsers. Theresults show consistency in case of three browsers.

The empirical patterns associated with the mobile internetusage were identified in Tossell, Kortum, Rahmati, Shepard, andZhong (2012). There were 24 participants of 19.2 years averageage in this study. The average number of browsing sessions perday was 3.86% and 50% of the users used browser for less thanthree times a day. Most of the browsing sessions (85%) were forsearching and google.com was used for this purpose. Our researchwork is more close to (Dunn et al., 2013; Shirazi et al., 2013; Tossellet al., 2012), and the results are comparable and complement thesestudies. Details are presented in discussions section.

3. Research methodology

This research was deemed to outline the characterization ofweb browser usage on smartphones. Mixed methods of researchare applied in this research; both qualitative and quantitativemethods were used. A through literature review was conductedthat revealed that this phenomenon was not discussed earlier, solimited knowledge was available regarding the usage patterns ofsmartphone web browser usage. The study was commenced withqualitative method i.e. interviews to explore the phenomenonand to form the basis of the qualitative method i.e. survey. In firstphase of the study seven in-depth interviews were conducted withexpert smartphone web users. The results were produced usingcontent analysis approach (Krippendorff, 2004), details are pre-sented in next sections. Here, the experts are defined as, thoseusers who are using smart phone browsers almost every day formore than a year’s time. They were engaged for a structuredinterview and were asked open ended questions about their webbrowser usage.

Frequently used browser feature, common tasks, number of ses-sions, and session duration were identified. This information wasanalyzed and survey instrument was prepared. After furnishingthe task list, tasks were categorized as basic and advanced tasks.These tasks and other information such as number of browser’ssessions per day and duration of session, common tasks performedwere used to prepare a survey. The survey population was 630respondents, contacted through social media, online survey andin-person meetings. Although, five age groups were created butsignificant number of respondents were from 3 age groups i.e. 18to 24, 25 to 34, and 35 to 44. Rest of the age groups were discardedand not discussed further in this paper. Majority of respondents(more than 60%) were from 25 to 34 years. Similarly, six experi-ence categories were created and majority of respondents were

3.1. Respondents’ profiles

Seven interviews were conducted with different respondents.All of the respondents were experienced in using Smartphonebrowser. Table 1 summarizes the profiles of the respondents theirexperience of using Smartphone browser experience and browserthey used of using. Regarding the population of survey, a total of630 individuals participated in survey. The number of people indifferent age and experience groups is presented in Figs. 1 and 2.Majority of respondents were male (65%). Respondents weredivided in four age groups and six experience groups. Experiencecategories were sought to cover all users, as the rise of smartphonestarted from 2010 so these groups can accommodate all of them(those who started using smartphones in 2010 or earlier and thosewho started using recently and all of them in between).

The duration of each usage session is increasing with the expe-rience. Experienced users tend to have longer browser usage ses-sions as compared to novice users.

The common tasks performed using browser were searching,sending/receiving emails, reading news, visiting social networkingsites and opening links as identified in qualitative phase. Thesurvey results revealed that searching is the most common taskperformed by respondents of all age groups. Respondents from35 to 44 years of age tend use browse more for sending and receiv-ing emails. Reading news using browser is equally popular in 18–24 and 25–34 years groups; however less number of people from35 to 44 years of age read news using browser. The trend of usingsocial network sites through browsers is more in 35–44 yearsgroups as compared to other groups.

The results of the correlation analysis show that tasks per-formed by the respondents from 18 to 23 years of age are stronglycorrelated (r = .934, p = .01) to the tasks performed by the respon-dents from 25 to 34 years of age. The tasks performed by therespondents from 35 to 44 years of age have weak positive corre-lation (r = .580, p = .03 and .344, p = .04) with the tasks performedby respondents from 18 to 24 and 24 to 34 years age categories.

The experience wise categorization of data related to the com-mon tasks performed using browser revealed that searching isthe most common among all experience categories. Sending andreceiving email as common task is selected by less respondentfrom higher experience groups. There is a significant trend of open-ing links through smartphone web browser in higher experiencecategories. The data show an increasing trend of reading newsthrough smartphone web browser with increase in experience.Respondents with more experience tend to use browser to readnews. The data about social networks is not consistent to makeconclusions.

4.2.7. Frequently used browser featuresThe top five frequently used browser features are represented in

Table 4 with respect to age of the respondents. It can be seen thatfour features i.e. opening a tab, closing a tab, page scrolling andswitching between tabs are the common in all age categories.However, two features changing home page and full screen modeare those which are not that popular in 18–24 and 25–34 yearsage categories.

The statistical analysis of the data revealed that the frequentlyused browser features are similar in all age groups.

The top five frequently used browser features with respect tothe experience are presented in Table 5.

The statistical analysis revealed that those having experience ofless than a year, their frequently used browser features arestrongly correlated (r = .710 and r = .732, p = .000) to those havingexperience of 1 and 2 years. They have weak correlation with thosehaving higher experience of 3, 4, or more than 4 years i.e. (r = .555,.551, .575, p = .000). Furthermore, respondents having experienceof 3, 4, more than 4 years, their frequently used browser featuresare strongly correlated i.e. (r = .801, .768, .765, p = .000).

5. Discussions

The smartphone web browser usage patterns are identified inthis study. The results include usage per day, duration of session,common tasks, and frequently used browser features. As men-tioned in the related works section that many studies have dis-cussed different aspects of smartphone usage. However, thisstudy is different from them as it only focuses the usage of webbrowsers. The results of this study complement the earlier studiessuch as (Bomhold, 2013), that searching is the most common taskperformed on smartphone web browsers. The use of smartphonebrowser is discussed in Shirazi et al. (2013), the results of thisstudy are comparable to it. The average length of a session was2.36 min in Shirazi et al. (2013), and in this study majority ofrespondents (33%) selected 1–5 min as their session duration.However, in this study the usage pattern related to different agegroups and experience groups are also identified. Patterns associ-ated to mobile internet usage were identified in Tossell et al.(2012), their results show that average number of sessions perday was 3.86 and 50% of the users used browsers for less than 3times a day. While our results show that 36% of respondents usebrowsers for 1–3 times a day and 37.5% respondents use for morethan 10 times a day. This increase is also representative of theincreased popularity of mobile web browsing.

The findings presented in this study should be generalized withcaution due to the limitations in this study. First of all, the samplesize of this study does not represent the whole range of smart-phone users, which is in millions. However, the sample size isequivalent or more than others studies. This study is not limitedto specific device or specific browser application because respon-dents had experience of using different devices and applications.

The PC studies related to use of web and browsers are not consid-ered in research. Future research may focus on the differences orsimilarities in PC and smartphone web browser usage.

6. Conclusion

In this paper, mix methods of research are employed to explorethe usage patterns of smartphone web browser. Respondents weredivided into categories with respect to age and experiences. Find-ings of this study include browser usage per day, duration of brow-ser session, common tasks performed using browser, andfrequently used browser features. Following conclusions are drawnfrom the findings: respondents from 35 to 44 years of age tend touse smartphone web browsers for less number of times in a daybut have longer sessions. While the respondents from other agegroups i.e. 18 to 24 and 25 to 35 tend to have more sessions ofshort durations. In terms of number and duration of usage sessionsthere is no significant difference in these two categories. Therespondents having more experience tend to use browser for moretimes a day and have longer sessions, while respondents with lessexperience use browser for less number of times a day and forshort duration per session. Regarding the frequently used browserfeatures, there is a pattern visible from data i.e. respondents can bedivided in two groups on the basis of their experience. Respon-dents having experience of less than one year, 1, and 2 years havesimilar pattern of using browser features and those having experi-ence of 3, 4 or more than 4 years have similar pattern. However,there was no difference in use of browser features among differentage groups. The work presented in this paper can also be used todevelop usability benchmark tasks for smartphone web browsers.
