N2 - We present a preliminary experiment to understand the variability of six simple movements. Six participants. wearing inertial measurement units on their wrist. performed six actions. The data collected were analysed using time-delay embedding theorem, PCA and percentage of cumulative energy to characterise variability in these movements. Of these movements, circular and 8-shape movements show a constant trend between participants; however, such a trend is not evident for static, horizontal, vertical and diagonal movements. Such analysis can be useful in determining different states of interactions with the display of user's behavior (enthusiasm, boredom, tiredness or confusion) over the course of training, practice or rehabilitation.
