Heat Map Voting

Choose this exercise

Purpose: Pinpoint which specific components of proposals attract participant interest without forcing an all-or-nothing decision.

Use it when: Use when evaluating multi-part concepts, design sketches, or complex proposals to highlight valuable details before final decisions.

Skip it when: Skip when the group must make a binding yes-or-no decision on an entire proposal or when ideas are single items that cannot be broken into parts.

Group arrangement: Individual silent voting followed by whole-room review

Timing: Participatory Methods records an estimated duration of 10 minutes. UWT allocates 15 minutes to allow quiet circulation and structured debriefing.

Materials and tools

• Sheets, cards, or posters displaying proposals or sketches
• Adhesive tape or clips to hang proposals on walls or whiteboards
• Sheets of small adhesive colored dot stickers (at least 20 per participant, with extra sheets available at a supply table) or fine markers
• Pad of standard sticky notes for brief explanatory notes
• One countdown timer
• Access to an interactive digital whiteboard platform (such as Miro or Mural) with pre-drawn digital dot shapes (for remote or hybrid delivery)
• Laptops or tablets for participants (for digital hybrid delivery)

Before participants arrive

1. Mount all proposal sheets along a flat wall or board with at least two feet of walking space between items.
2. Place sheets of small dot stickers, sticky notes, and fine markers at each participant seat, with extra dot sheets on a central table.
3. If running digitally or hybrid, upload all proposal images into the online whiteboard canvas with banks of small dot icons next to each proposal.

Say this to open

We have several proposals posted on the wall. Instead of voting for an entire poster, look for specific sentences, buttons, steps, or features that stand out to you. Place your dots directly on those individual elements.

How to run it

1. Review proposals and criteria 3 minutes

   Briefly walk the room past the posted proposals so everyone understands each item. Clearly state the guiding criteria for voting, such as user impact or technical feasibility. Give one neutral example: if a poster has four paragraphs, explain that a dot belongs next to paragraph two rather than in the sheet corner.

2. Silent dot voting 5 minutes

   Invite participants to circulate in silence. Direct half the group to start on the left and half on the right to reduce crowding. Participants place dots directly on specific phrases or sketch details they support, taking more dots from the supply table if needed. Participants may post a sticky note beside a dot to explain their reasoning. Anyone preferring not to mark may observe silently.

3. Observe clusters 3 minutes

   Call time and gather everyone in front of the display. Direct the group to stand back and silently scan the boards. Ask them to notice which specific lines or features gathered dense clusters and which parts received no dots.

4. Analyze and prioritize 4 minutes

   Lead a short discussion focused strictly on the heaviest dot clusters. Invite three or four participants to explain why specific elements earned their marks. Record these top-rated components to carry into the next phase of work.

Debrief questions

• Which specific component gathered the densest cluster, and what makes it compelling?
• Did any detail surprise you by receiving high attention or being passed over?
• How can we combine two or three of the highest-rated parts into our next draft?

Finished output: A visual display of posted proposals marked with dot clusters, identifying the specific features the group prioritizes.

Remote

Upload proposal images or text blocks to an interactive online whiteboard. Provide an unlimited supply of tiny digital dot shapes in the board margin. Set a 5-minute timer for participants to drag dots onto specific lines or diagram parts in silence, followed by a shared screen review.

Hybrid

Use a digital-first approach where all proposal sheets sit on an online whiteboard. In-person participants open the board on individual laptops or tablets, while remote participants join the same board. If individual devices are unavailable, designate an in-person scribe with an open camera trained on the wall. Remote participants type line numbers or coordinates into chat (for example, 'Poster 2, Paragraph 3, 2 dots'). The scribe places physical stickers on their behalf after placing their own votes.

Access and participation choices

• Mount materials at seated eye level or provide printed paper copies for participants who prefer to review and mark at a table.
• Participants may pass on placing dots, walk the gallery without voting, or vote on only one element without speaking during the debrief.

If the session gets stuck

Participants place dots in the blank margins or header of a poster instead of on specific elements.

Remind the room immediately that corner dots will be counted as general interest, but the goal is to pinpoint exact sentences, lines, or diagram components.

A crowd blocks one popular poster while other posters remain unviewed.

Direct participants to skip crowded posters for now, review empty posters first, and return to the popular board once space clears.
