Embodiment Scale

During last year, I have been developing a way to evaluate embodiment experience in videogames. I will present the scale development study in the Academic Mindtrek ’16 (Tampere, Oct 17th to 19th, 2016).

The scale is based on work by Longo et al. (2008) who developed a psychometric scale for evaluation embodiment in rubber hand illusion.

Embodiment scale (7-point Likert-scale, strongly disagree–strongly agree) with two subscales:

Controller ownership subscale

• I perceived the game controller as a part of my body
• perceived the game controller as an extension of my body
• It seemed like the game controller had disappeared

Player-character embodiment

• It seemed like I was in the location where my character was
• I perceived the character I control as an extension of my body
• It seemed like the character I controlled was I

The average of all items or average of subscales separately can be used as the embodiment score.
