Exploring user usability perceptions and acceptance of chording-enabled keyboards: A perspective between human-computer interaction

Abstract

In recent years, a variety of alternative keyboard designs have emerged with the primary goal of enhancing user comfort and productivity compared to conventional keyboards. The objective of this study was to determine the variables affecting the acceptance and perceptions of people towards chording-enabled keyboards. A holistic analysis was done with the use of an extended framework of unified theory of acceptance and use of technology (UTAUT2), analyzed through partial least square structural equation modeling. Gathering a total of 430 valid respondent through purposive sampling, perceived usability, behavioral intention, usage behavior, habit, performance expectancy, social influence, and hedonic motivation were seen to be important factors in adopting chord-enabled keyboards. From the output, it was posited that the attributes of the keyboards' functionality, ease of use, adaptability, and people's willingness to use it, significantly affected their intention of using the keyboard. The findings and suggestions included in this study will benefit not only users but also the developers by providing insights into user preferences. Efficiently improving and marketing chording enabled keyboards could be considered as suggested in the implications. Moreover, the study's model construct could also be utilized in other studies related to user acceptance of technology in different countries.
