When we talk about communication in digital environments, we tend to default to spoken and written language. Text chat. Voice chat. Emojis, if we are feeling adventurous. Yet in practice, much of what happens online escapes words (spoken or written ) altogether. Through my doctoral research, in which I explored how autistic and ADHD teenagers interact in Autcraft, I found that communication often unfolded through objects themselves, quietly, persistently, and with remarkable precision.
In Minecraft, players inhabit a world built entirely from blocks. Everything is material, placeable, and editable. Crucially, these materials are not passive. Players repurpose them, assign meaning to them, and rely on them to communicate across time, space, and sensory difference. What emerges is a form of communication that is neither accidental nor secondary. It is intentional, adaptive, and deeply relational.
Objects as messages, not decoration
One of the most consistent patterns in my data was the use of in-game objects as communicative tools rather than aesthetic embellishments. Wooden signs, for example, became central to how players maintained relationships across time zones.
Players didn’t always log in at the same time. Live chat was therefore unreliable. Instead, signs carried instructions, decisions, reminders, and feedback, all embedded directly into the environment. The game world itself functioned as a record of shared understanding. Where players could not synchronise their time, the space held the conversation open.
Signs also carried emotional and practical weight. They marked boundaries. They narrated histories. By naming areas within a base, players made space predictable and navigable. Naming anchored the environment, reducing ambiguity and supporting a sense of safety. In that sense, stability occurred by design.
By turning space into something readable, players shaped environments that supported regulation as much as movement.
Colour, pattern, and implicit meaning
Not all communication took explicit form. Often, meaning was conveyed through repetition and pattern rather than text. Wool blocks, available in a broad colour range, were frequently used in ways that were abstract yet precise.
In one example, blue wool embedded into the floor created a series of arrows guiding visitors through a large structure. Elsewhere, recurring colour schemes echoed personal symbols important to the builder, extending identity beyond avatar skins into architecture. These were not instructions written out in words. They were cues legible to those who understood the space’s logic.
This mode of communication relies less on linguistic decoding and more on pattern recognition. For neurodivergent players in particular, it offers a route to shared meaning that does not depend on speed, verbal fluency, or social timing.
Banners, books, and symbolic presence
More complex artefacts facilitated communication across multiple layers. Custom banners functioned as markers of affiliation and memory. Hung above entrances or displayed prominently, they signalled belonging without explanation. They communicated history, identity, and community at a glance.
Books introduced a different register altogether. Players used them to leave longer reflections, instructions, or personal narratives within their bases. Reading a book in Minecraft requires a pause. You must stop what you are doing, open it, and attend. In doing so, books slowed communication down. They offered depth without interruption.
What matters here is not the novelty of these tools, but their persistence. They allow players to communicate across time, to be present without performing, and to be understood without immediate response.
Why this matters for technology design
These practices disrupt narrow assumptions about what communication is supposed to look like in digital environments. They show that interaction need not be fast, verbal, or reciprocal in real time to be meaningful. Communication can be environmental. It can be something you encounter, revisit, and interpret.
For autistic and ADHD users, this has significant implications. Objects do not hurry you. They do not demand eye contact or an instant reply. They remain available, holding meaning until engagement is possible.
From a design perspective, this suggests a shift in priorities. Rather than centring speed and constant responsiveness, technologies should value persistence, clarity, and choice. Communication should be something users can step into, not something that interrupts them.
Communication, rethought
What my research makes visible is that communication is not confined to messages exchanged between people. It also lives in the spaces we build, the objects we leave behind, and the systems we shape together.
In Minecraft, players did not simply adapt to the platform. They reshaped it to meet their communicative needs, turning blocks into language and environments into dialogue. Paying attention to these practices gives us more than insight into a game. It offers a framework for rethinking communication in digital worlds and for questioning whose ways of communicating are treated as valid in the first place.
