The global smart home market is expected to reach an estimated $107.4 billion by 2023 according to Lucintel, a market research company.9 Deloitte reports a 20-30% increase in user interests since 2015 in its recent smart home consumer survey in Germany.4 Nevertheless, the smart home concept is yet to be realised on a mass-scale basis.5 Though an abundant knowledge resource and ever-increasing academic and industry research interest in smart homes exist, these studies often ignore the concept of the household as a complexity of relationships and rather advance the concept of smart homes as a sterile place, neutral and bland.13 The current focus tends to place the household on a backbench, with design and development concentrating on a new kind of smart household ignoring the current intricacies especially the individual member roles of the household. The design and development of smart homes should however trigger and answer questions of how smart home technologies can merge and flow seamlessly or be domesticated into the household setting. It is necessary that dimensions of research, such as the gender dimension, into the ever-changing notions of family and households to boost mass-scale user adoption, is investigated.
According to the European Commission, the term gender dimension refers to the integration of sex and gender analysis into research and innovation.14 This extends beyond the collection of statistical data on gender, for example, the number of males or females in a study sample population. It is also not an add-on at the end of the project but drives the research. Gender dimension in research allows researchers to query gender norms and stereotypes, reconsider standards and reference models leading to an in-depth understanding of both genders' needs, behaviours and attitudes. It enhances the societal relevance of the knowledge, technologies and innovations produced and contributes to the production of goods and services better suited to potential markets.14 Gender dimension acknowledges that potential gender differences exist and seeks to accommodate these differences in innovation. In the field of computing, in game development, most games end up being marketed and sold to males ignoring females as a potential market.15 Adding on the gender dimension means researching into male and female game interests and designing and developing with such interests in mind. Another example of the need for gender dimension in research is the Pregnancy Crash Test Dummies which allows for the testing of car seat belts with 'pregnant-looking' crash test dummies to avoid foetal deaths which is most rampant with conventional seat belts.16
In understanding why gender dimension must drive smart home innovation, it is important to note that the home remains one of the most gendered spheres of society in most cultures17 with most of what people do within a household being culturally determined by gender.11 And in western countries, there is a significant gender division within the modern family home  with women still taking on the higher percentage and spending much more time on household chores as compared to males.10 For example, Tjorring et al. in their study on saving electricity in the home believe the correct strategy is to address the woman in the household as she is normally solely or partially responsible for using the relevant energy-consuming appliances.17 Smart home innovation must concentrate on what is happening now in the home, who does what in the home and how these users' interests can be addressed.
The consideration of the gender dimension in smart home research will allow a new outlook on the different preferences and needs of gender in a home. The home has different connotations to men and women and thus a consideration of potential (e.g. behavioural) sex-gender differences in innovation avoids the delivery of stereotype-driven products. It is thus in order that the gender advisory group for the EU Research and Innovation Programme Horizon 2020 advises that adding on the gender dimension in Smart Home innovation might be the answer to untapping the potentials of energy efficiency from smart homes.8
there are already recurring reports of smart home devices being used to facilitate domestic violence
There are several study results on the varying barriers to smart home adoption.2,3,5 These studies seek to answer the questions of who smart homes are being currently developed for, what factors will exclude others from adopting smart homes and what can be done by designers and developers to satisfy most users. I have categorised the most frequently user-identified barriers to smart home adoption into these two: privacy & security and cost & knowledge. In the next paragraphs, I will discuss these barriers and touch on why gender dimension is needed (with specific gender examples) in addressing these barriers.
Privacy & Security: Domestic violence is the most common form of violence that happens globally against women. One out of three women in the world has been beaten, coerced into sex, or otherwise abused in her lifetime and the abuser is usually a family member or someone otherwise known to her.18 Violence against women occurs predominantly behind closed doors at home with most cases having never been reported to police.6 How can the design and development of smart home innovations empower women at home to protect themselves from violence? Even now, there are already recurring reports of smart home devices being used to facilitate domestic violence with smart home devices becoming the new digital tools of abuse.12 Smart home devices are being used by abusers to stalk victims, give them a sense of insecurity in their homes, make them feel they are crazy or monitor victims' activities at home. The concerns of privacy and security in the home can range from harmless deeds to life threatening issues. Smart homes should provide occupants with an assured sense of security. That sense of the home as a haven and comfort zone should as well be found in a smart home. As privacy and security concerns differ for each member of a household, it is necessary that levels of privacy are defined and guaranteed. Enabling gender and sex analysis to lead smart home innovation will bring these issues to fore. Participatory design sessions with members of households will allow designers and developers to identify these concerns, factoring them into design. As much it is important for industry to gain a mass scale of market adopters, it is equally if not highly important that individual privacy concerns and security levels should be inputs in design to avoid life-threatening problems.
Cost and Know-How: The use of technological innovations to facilitate societal division and exclusion has often been criticised by several researchers. Balta-Ozkan et. al highlight the current exclusivity of smart homes for tenants and those on low incomes as well as users with low technological know-how.2 With smart homes marketing imagery often showing young to middle-aged white couples often with a single young child5 and often middle class, it fails to reflect the varying notion of a family. Or perhaps is this marketing imagery the means in defining who is included or excluded from owning a smart home. How are the varying economic situations of users taken into consideration in smart home innovation? Will smart home innovation only facilitate social exclusion for certain groups? Industry often tends to concentrate on wealthy and well-educated male users who can afford such homes and often stereotyped to be 'tech-savvy', however there exist other users who can be socially isolated due the inability to afford smart home devices or assume they are meant for the 'tech-savvy'. In the EU, the largest age group are the baby boomers (40-50 years old) who will within the next 20 years go into retirement.7 Women remain the least earning members of the workforce and have highest number of unemployment rates. In addition, women tend to live on the average 4 years longer than men. A consideration of these factors brings to fore a new potential market that will need the most affordable forms of smart home devices enabling these women to live independently as required. An additional example would be that of the growing number of single-parent households who often are more vulnerable to poverty and marginalisation.7 This is another new potential market that would need smart home innovation to support their parental roles yet be extremely affordable. The subject of how much 'tech-savvy' one must be to use technology can as well deter users from technology use, especially for age groups that have not required such technology till now. Nevertheless, in performing participatory design sessions with these users, user-inspired simple-to-use interfaces and devices can be designed that require little or no special training to use. And as these are user-driven, the possibility of acceptance is very high.
smart home innovations can benefit from the resources of sex and gender analysis
Smart home innovations can benefit from the resources of sex and gender analysis which would address the varying concepts of homes, member roles and the makeup of a household. The identification of possible gender differences in society and in the concept of a home does not only create new potential markets but it also allows the satisfying of specific user needs. In this article, I have discussed the need, with examples, to consider the gender dimension in driving smart home innovation. The concept of privacy is as unique as every user with privacy concerns in a home differing with each member of the household. It is necessary that all users of the household are considered in the design of smart homes with design and development stripped of stereotyping. The consideration of factors such as economic income based on gender can as well be beneficial in avoiding marginalisation or social exclusion. This would allow smart homes to be available to all regardless of their economic situation. In conclusion, it is relevant that the home is not separated as a bland entity in need of technology add-ons but using the gender dimension, the intricacies of the home and its members are researched and used as the foundation for design and development of smart home Innovations.
