You’ll notice that a groov interface doesn’t include a lot of bells and whistles
No fancy graphics, few bright colors. The gadgets are basic graphics—gauges, buttons, sliders, LEDs.
There’s a reason for this restraint.
It turns out that fancy graphics obscure valuable information, and a lot of bright colors keep you from seeing what’s really important.
Frankly, a lot of HMIs don’t provide operators with the clear information they need to monitor and control their equipment.
In fact a lot of HMIs are pretty ridiculous—you can’t tell by looking whether the system’s OK or about ready to blow up. Could be important.
So what happens? Wasted time, wasted materials, lost production, damage to equipment, accidents.
But a lot of study has been done on how to build an effective HMI, and groov was designed from the ground up with high-performance HMI principles in mind.
So groov encourages you to build an HMI that works:
- Gadgets are clean and simple—no gel buttons or 3D effects.
- Background colors are muted, so the important data stands out.
- Data is presented in analog instead of digital form, so humans can understand it faster.
- Live data is colored dark blue to distinguish it from static text.
So is groov an HMI?
Absolutely. Depending on your system, you can build your complete HMI in groov. But you can also use it as a supplement for an existing HMI, to provide a subset of data or control to specific people. Since it’s so easy to use, you may want to start this way.
