On Eliciting a Sense of Self when Integrating with Computers

EmbER: A System for Transfer of Interoceptive Sensations to Improve Social Perception

“…), and (3) categorize these particular distortions or amplifcations based on their reported frequency. This allowed us to understand participant experience of both video narrators and feedback without the infuence of personal diferences across users and their own self-refection interfering with their actual experience, which is typically found in direct self-report surveys and can diminish accuracy [11].…”

“…After the three videos and three surveys were complete, the participant engaged in a phenomenological interview to systematically understand how the participants experienced the narrators, and how the experience was infuenced by EmbER. A phenomenological interview is a useful complement to questionnaires, as it seeks to systematically evaluate experiential aspects of device usage without relying on explicit and refective self-judgments [11].…”

Wearable systems without experiential disruptions: exploring the impact of device feedback changes on explicit awareness, physiological synchrony, sense of agency, and device-body ownership

“…Studies have shown that this sense can be extended beyond our biological bodies to artificial limbs or tools due to the plasticity of our brain (Botvinick and Cohen, 1998;Lewis and Lloyd, 2010;Ponzo et al, 2018). To distinguish this notion from sense of body-ownership over one's biological limbs, we refer to this phenomenon as the "sense of device body-ownership, " where one develops a feeling of ownership toward an external device when it is sensed through multisensory correlation and fit within the user's body-model (Tsakiris et al, 2007;Danry et al, 2022). For humans, the sense of body-ownership can sometimes be disrupted in certain neurological or psychiatric conditions, where distortions in the sense of body-ownership have been linked to disorders like schizophrenia and depersonalization (Sass and Parnas, 2003;Sass, 2014).…”

“…For instance, as many as 40% of individuals fitted with a prosthesis either rarely use it or abandon it altogether (Biddiss and Chau, 2007;Brandebusemeyer et al, 2021). Preliminary evidence suggests that one key reason for this attrition is the increased cognitive load and explicit device awareness imposed by these devices (Slater et al, 2003;Murray, 2004;Li et al, 2019;Danry et al, 2022) such as increased attention, concentrates or focalization of the devices in our immediate experience (see Figure 1). However, it is still unclear what factors in wearable devices generate this cognitive load and explicit awareness, as well as how wearable devices can operate to minimize such influences cognitive load and awareness.…”

“…Recent studies have focused on sense of agency and sense of body ownership as predictors for successful use where the actions performed with a system are either attributed with a feeling of "I did that" instead of "the device did that" (Kasahara et al, 2019;Cornelio et al, 2022) (Sense of Agency) or a feeling like the device has become part of the user; "I did that with my body" rather than "I did that with the device" (Sense of Body Ownership) (Lopes et al, 2021;Danry et al, 2022). There is evidence that suggests that wearable devices that require or cause more frequent explicit awareness lead to lower adoption due to a diminished sense of agency and sense of device-body ownership (Murray, 2004).…”
