While several instruments for evaluating perceptions and attitudes towards various technological instances exist
[18, 84], a gap remains in the assessment of attitudes towards technologies that blur the boundaries between
humans and machines [58, 82] as for example Electrical Muscle Stimulation (EMS) to improve reaction times [39],
or the use of wearable robotics to control multiple supernumerary limbs at the same time [71]. To address this
gap, we constructed the SHAPE scale. As a first step, we conducted an analysis of existing studies and measures
in related research fields. This analysis aimed to synthesize the data from instruments with intersecting concepts,
such as the sense of agency [81], or attitudes towards assistive technology users [27], and inform the development
