# Back-to-Back Drawing Pairs sit facing away from each other while one person describes a hidden drawing without naming it, and the other reproduces it using only verbal cues. Partners then compare sketches side by side to inspect where verbal instructions held or drifted. **Time:** 20 minutes. Participatory Methods suggests 20 to 30 minutes; SessionLab notes quick rounds. This 20-minute run sheet provides two structured rounds, comparisons, and a full-room debrief. **People:** 4 to 24. Pairs sitting back-to-back or facing away from each other ## Choose this exercise **Purpose:** Demonstrate the gaps between verbal descriptions and listener interpretation through a direct side-by-side drawing comparison. **Use it when:** Use during communication or collaboration training when you want participants to examine assumptions, descriptive clarity, and the need for clarifying questions. **Skip it when:** Skip when group members cannot sit comfortably or write/draw, or when working on tasks requiring written documentation rather than verbal real-time exchange. ## Materials and tools - One clipboard or firm drawing surface per participant - Two sheets of blank paper per pair - One pen or pencil per participant - Two distinct reference cards showing geometric shapes per pair (Cards A and B) - Digital versions of Reference Cards A and B (image files or PDFs) for remote or hybrid delivery - One countdown timer visible to the room ## Before participants arrive 1. Arrange chairs in pairs placed directly back-to-back across the room with sufficient space between pairs to prevent audio cross-talk. 2. Print or prepare Reference Cards A and B, keeping them face down so artists cannot see them. 3. If running remotely or hybrid, prepare digital image files of Reference Cards A and B ready to send via direct message. ## Say this to open Find your partner and take seats placed back-to-back. One of you will be the describer first, and one will be the artist. Describers, you will receive a reference image that your partner must never see. You must guide your partner to draw it accurately without naming the overall composite object. Focus purely on shapes, relative positions, line directions, and sizes. Artists, your task in this first round is to draw what you hear in silence without asking questions. ## How to run it ### 1. Form pairs and distribute Round 1 materials (3 minutes) Instruct participants to pair up and sit back-to-back. If there is an odd participant or someone opting out of drawing, assign that person to join an existing pair as an active observer. Hand Reference Card A face down to the first describer in each pair. Hand blank paper and a pencil to the artist. Deliver the opening script and confirm artists understand they must not turn around or view the card. ### 2. Execute Round 1 drawing (4 minutes) Start a 4-minute timer. The describer turns over Card A and verbally instructs the artist. Explicitly state that clarifying questions from the artist are not allowed in this round; this round is strictly one-way communication. Example rule: The describer may say 'Draw a medium circle in the upper third of the page, then draw a horizontal line touching its base,' but may not say 'Draw a lollipop.' Stop when the timer sounds. ### 3. Reveal, compare, and switch roles (3 minutes) Instruct pairs to turn around and place Card A directly beside the drawing. Allow 90 seconds for pairs to identify specific alignment and divergence points. Then instruct them to switch roles, sit back-to-back again, and hand Reference Card B face down to the new describer. ### 4. Execute Round 2 drawing (4 minutes) Start a 4-minute timer. The new describer guides the new artist using Reference Card B. Explicitly permit two-way dialogue this round: artists may ask clarifying questions such as 'Does the line extend left or right?' or verify details before drawing. Stop promptly at the time limit. ### 5. Final comparison and whole-room debrief (6 minutes) Pairs turn around and inspect Card B beside the second drawing for 1 minute. Convene the full room for the debrief. Collect 3 to 4 quick observations from different pairs addressing the debrief questions. ## Debrief questions - What specific words or spatial descriptions caused the most confusion while drawing? - How did the drawing accuracy change when the artist was allowed to ask clarifying questions? - What assumptions did the describer make about what the artist already understood? **Finished output:** Each pair produces two completed sketch comparisons illustrating how verbal instructions translate to visual execution; pairs with an observer produce one set of notes on communication breakdowns. ## Remote Place participants into 2-person breakout rooms. Send the reference image via private direct message to the describer only. The artist draws either on an online whiteboard (in a private frame or personal board hidden from the describer until the reveal) or on physical paper at their desk (keeping their camera off or pointed away from the page). When time is called, both reveal their drawings by turning on cameras or sharing their screen to compare the source file and sketch side by side. ## Hybrid Pair in-person participants together back-to-back in the room. Pair remote participants together in individual breakout rooms with digital images sent by private chat, ensuring any digital sketch area remains hidden from the remote partner until the reveal. Avoid mixing in-person with remote individuals in a single pair to preserve equal audio clarity and prevent accidental visual peeking. ## Access and participation choices - Participants may sit in standard chairs positioned back-to-back, side-by-side facing opposite directions, or separated by a partition if back-to-back seating is uncomfortable. - Participants who prefer not to draw or speak may act as observers; they join an existing pair rather than forming an incomplete pair, taking structured notes on communication breakdowns for the debrief. - Participants may keep their final sketches private between partners without presenting them to the full room. ## If the session gets stuck **Describers accidentally peek at their partner's paper or show their reference card.** Remind the room immediately that the experiment works only when visual feedback is zero. Ensure chair backs touch or are placed directly opposite. **The room becomes so loud that partners struggle to hear each other.** Spread pairs across the edges of the room or into an adjacent corridor, and remind describers to use a calm, low conversational volume. ## Terms used here - Two-way communication: An exchange where the receiver can ask clarifying questions and verify instructions rather than simply absorbing input. ## Participant material: Reference Card A: Geometric Composition Image layout instructions for facilitator to print or draw: - One large square centered on the page. - An equilateral triangle sitting on top of the square, sharing its top edge (like a roof). - A small circle inside the square, positioned in the top-right corner. - A straight diagonal line crossing from the bottom-left corner of the square to the center of the square. Rule for describer: Do not name everyday composite shapes like 'house' or 'tent'. Describe only geometric lines, intersections, sizes, and orientations. ## Participant material: Reference Card B: Abstract Linear Network Image layout instructions for facilitator to print or draw: - A horizontal straight line running across the lower third of the page. - Three vertical parallel lines of equal height extending upwards from the horizontal line, spaced evenly. - A medium circle surrounding only the center vertical line. - Two parallel diagonal slashes crossing through the top of the right vertical line at a 45-degree angle. Rule for describer: Do not describe recognizable objects. Describe only relative spatial positions, lengths, and shapes. ## Sources and adaptation Observed in the SessionLab Methods library (submitted by Erica Marx) and in the Participatory Methods catalog. Both cite earlier workshop practice including ventureteambuilding.co.uk. The core mechanic of pairs sitting back-to-back with one describing a hidden image and the other drawing is preserved directly from Participatory Methods and SessionLab records. UWT structured the activity into a definite two-round progression (Round 1 strictly one-way without clarifying questions, Round 2 two-way with full verification permitted), provided reproducible card templates, defined observer integration, and added explicit hybrid rules and timing.
