Obscuring Undesirable Individuals to Alleviate Social Discomfort Using Diminished Reality
This is a conceptually striking CHI paper because it turns a standard HCI value proposition on its head: instead of increasing connection, it uses diminished reality to support avoidance. The contribution is strongest as a reframing plus a controlled prototype study, not as a general solution for social discomfort.

Review Summary
This paper stands out because it makes an unusual but clearly articulated move in HCI: it treats avoidance as a legitimate interaction goal rather than a failure of social design. That is the core departure from common sense and from the dominant field framing, which usually optimizes for connection, inclusion, or engagement. The novelty is therefore partly conceptual and partly technical. Conceptually, the paper introduces an "avoided individual" as a design target and positions diminished reality as a way to reduce social discomfort by obscuring perceptual cues. Technically, it evaluates occlusion methods and social distance in a mixed-reality office scenario, which gives the work some empirical grounding beyond a speculative proposal. The validation is real but bounded: it is a controlled experiment with 62 participants, self-report measures, and a specific MR prototype. That means the paper supports claims about the studied setting and the immediate perceptual/social effects, but not broad deployment claims. The limitations are important and appropriately acknowledged: the manipulation is visual-only even though social presence is multisensory, the study does not include the perspective of the obscured individuals, and governance or regulatory safeguards are not systematically addressed. The results are also more nuanced than a simple "more occlusion is better" story. The paper reports that semi-transparent masking often performs best, while wireframe and geometric occlusion can rebound on anxiety or presence measures, which is a useful design insight rather than a trivial confirmation of stronger filtering. In CHI terms, this is a strong honorable-mention style contribution because it opens a new design space and provokes discussion about ethics and social comfort, but it should be read as an early-stage exploration rather than a mature intervention ready for real-world use.
What Changed
Canon before
HCI work on social comfort has largely emphasized connection, inclusion, and pro-social interaction; avoidance-oriented support is comparatively less developed.
Departure from common sense
The paper deliberately inverts the usual HCI goal of helping people connect, instead treating social avoidance as a legitimate design objective and using diminished reality to make an unwanted person less perceptually salient.
Actual novelty
Its main novelty is not a new DR primitive alone, but the reframing of DR as a social-comfort intervention for an "avoided individual" plus an empirical comparison of occlusion methods and social distance in that setting. The paper contributes a concrete design target, a mixed-reality prototype, and evidence that the effectiveness of masking is non-linear: semi-transparent occlusion often outperforms both minimal eye masking and fully blocking approaches. That combination makes the work more than a simple application demo; it is a design-space contribution with an empirical ordering of techniques in a socially sensitive context.
Evidence
The paper positions itself against the dominant connection-oriented HCI framing and proposes an "avoided individual" design target. Validation is a controlled mixed-reality experiment with 62 participants, manipulating social distance and occlusion method, and measuring social anxiety, social presence, acceptance, and interview-based ethical reflections. The authors also state explicit limitations around visual-only manipulation, missing perspectives from obscured individuals, and incomplete governance analysis.
“and social distance. Results indicate that DR significantly reduces users’ social anxiety and sense of social presence. Moreover, participants generally expressed positive attitudes toward usage intention and ethical considerations. This work extends HCI research on social comfort, shifting the focus from “facilitating connection” to “supporting avoidance””

Limits
Method limits
The evidence comes from a controlled mixed-reality office study with self-report outcomes, so it supports the claimed effects in that setting but not broader causal or longitudinal claims. The paper also notes that social presence was manipulated visually rather than multisensorily, and that some effects vary non-linearly across masking styles rather than monotonically with stronger occlusion.
Deployment limits
The approach is not yet validated for real-world deployment, where ethical review, misuse prevention, and governance constraints would be central. The paper itself notes that it does not systematically examine regulatory frameworks or governance mechanisms, and it does not test how the system behaves in live social settings with real interpersonal consequences.
Boundary conditions
Findings are bounded by the office MR scenario, the specific occlusion methods tested, and the social-distance manipulations. The paper also acknowledges that social presence is multisensory and that the study does not include first-hand experiences from the obscured individuals. The strongest effects are reported for semi-transparent masking, while eye masking alone is weaker for social presence.
Position in field
This is a provocative CHI contribution that shifts the design conversation from facilitating connection to supporting avoidance. Its significance lies in reframing a familiar MR capability into a socially sensitive application domain, while remaining grounded in a controlled prototype evaluation and a careful discussion of ethics, fairness, and possible misuse.
