CAPTRON Highlights the “Human” in Human-Machine Interfaces

The buzz around MODEX 2026 consisted of towering automated storage systems and swarms of autonomous mobile robots. While these systems certainly drive the future of supply chain management, there is another element that cannot be overlooked: human-centric automation. CAPTRON provided an exhibition of several examples of this interaction between people and systems.

Many companies proclaim a ‘lights-out automation’ future, with robots dominating the landscape, but it’s simply impractical for many facilities. CAPTRON presented hardware and software solutions with the intuitive Pick-by-Light system paired with rugged capacitive sensors. Perhaps this new ‘Physical AI’ isn’t always focused on taking control away from people, but instead providing them with tools and techniques to perform better, faster, and more reliably.

Pick-by-Light for Order Fulfillment

The centerpiece of CAPTRON’s booth was the Pick-by-Light system. This setup uses segmented RGB LED strips and pick confirmation via code scans or capacitive buttons. The purpose is to guide order pickers directly to the correct bins, and in the proper sequences, all with the flexibility to be able to make changes as the system requires.

Pick-by-Light combines the LED indicators with bin-mounted 2D code confirmation for order pickers.

Simplicity is the name of the game for this application, and that goes both for the user and for the system administrator. For the order picker, colors can be determined for each employee, and a quick scan of a code by a handheld device can confirm the pick or provide a quick indication if it was incorrect. For the programmer, a back-end interface allows quick configuration for different product patterns, so even if the warehouse is huge, the setup can still proceed without a long downtime.

CAPTRON’s Legacy: Capacitive Sensing

Beyond fulfillment (although still applied to the overall warehouse management theme), CAPTRON highlighted its broad range of capacitive sensors and HMI devices. Mechanical push buttons are notorious for failures due to dust collection and repetitive pressing over the years. Building reliable, rugged capacitive technology removes ingress points and mechanical motion that lead to wear and failure.

These capacitive devices not only provide an input for the technician or operator, but they can also be outfitted with display technology, making it truly an I/O device, all in one. Various models include not only the capacitive input, but also include LED illumination and text display for alphanumeric characters. These are very important in today’s world of high turnover rates, because without some sort of indication, operators must learn their jobs simply by repetition and memorization, which is prone to errors and takes time.

Augmentation, not Automation

Perhaps one crucial takeaway from CAPTRON’s MODEX display is one of moderation. Certainly, automation is important. The fact can’t be overlooked or understated. But to pursue electrical and mechanical automation at the expense of the rest of the operation is also a mistake.

Sometimes, automation may be as simple as a more ergonomic sensor that reduces cognitive load and physical fatigue. Or a simple method of using human senses to accelerate and give more reliability to bin-picking operations. By focusing on people and intuitive interfaces, CAPTRON is helping companies address labor shortages by simply making the jobs of current employees safer and more effective.

Understanding the Future of Automation

Every company at MODEX hoped to present a unique vision to customers, a vision that would be received and embraced with enthusiasm. CAPTRON proved that often, the most compelling visions are those that bring human and machine together by offering both top-of-the-line control system technology and ease of operation for employer and employee alike.
