FSR Seat Centroid Visualizer

Click sensors to cycle pressure levels, or use the sliders to move a simulated load. The orange marker shows the weighted center of pressure.

Directions: front of chair = top, rear = bottom, left/right follow the seat map. Presets and sliders update the sensor pattern; the weighted sums and centroid update from the active sensor values.

Interactive Grid

Front of chair is at the top Orange marker = centroid
X: left to right. Y: rear to front.

Slider Simulator

Target X

0.00
Move the simulated load left or right.

Target Y

0.00
Move the simulated load rearward or forward.

Spread

0.38
Smaller spread concentrates the load. Larger spread distributes it.

Intensity

1.00
Scales the overall pressure level.

Centroid Equations

\[ \mathrm{sumX} = \sum_{i=1}^{N} x_i p_i, \qquad \mathrm{sumY} = \sum_{i=1}^{N} y_i p_i, \qquad \mathrm{total} = \sum_{i=1}^{N} p_i \] \[ c_x = \frac{\mathrm{sumX}}{\mathrm{total}}, \qquad c_y = \frac{\mathrm{sumY}}{\mathrm{total}} \]
