A user interface design that incorporates virtual or digital knobs on a touchscreen display and enables users to interact with the interface through virtual knob controls is referred to as “Knob-on-Display HMI”.
In this context, the phrase denotes the existence of controls that resemble knobs and can be turned directly on the display surface to simulate turning actual knobs.
In order to give consumers a comfortable and tactile manner to engage with a digital system while exploiting the adaptability and dynamic nature of a touchscreen interface, the Knob-on-Display HMI was developed.
In situations when traditional physical knobs are preferred for precise control, a design like this might be employed, but the interface can also offer extra functionality and context-specific controls utilizing a digital display.
For instance, a Knob-on-Display HMI in an automobile entertainment system might use a touchscreen display with virtual knobs for temperature, volume, and other settings.
The digital system would react appropriately as users rotated their fingers on the touchscreen surface to engage with these virtual knobs, simulating the feeling of turning real knobs.
It is important to stress that the phrase “Knob-on-Display HMI” may be unique to particular industries or specialized circumstances and may not have widespread acceptance or conventional usage. It is advised to examine current research or authoritative sources in the relevant subject to comprehend the precise implications and applications of such a concept.
The Global knob-on-display human-machine interfaces(HMI) market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
As the first automotive-grade touchscreen controller family to natively support the detection and reporting of capacitive rotary encoders as well as mechanical switches on top of a touch panel, Microchip Technology Inc.
announces the maXTouch, Knob-on-Display (KoD) family of touchscreen controllers. By mounting the knob directly onto the display without cutting a hole in the panel or altering the touch pattern, as opposed to the old mechanical rotary encoders, the new approach increases design flexibility and reduces system costs.
With the KoD technology, designers may quickly incorporate a different knob count, form, and location to support a variety of end-user products without the requirement for bespoke touch sensor patterns.
The maXTouch KoD touch controller’s customizable configurations can be changed without affecting the integrated firmware, resulting in a quicker and more adaptable development cycle.
With the maXTouch KoD controller, designers can maintain the convenience of a rotary encoder input device while incorporating it into a cutting-edge interior design that utilizes smart surfaces and multi-touch screens.Building a sealed Human-Machine Interface (HMI) module, which is becoming more and more common for industrial and domestic appliance applications, is another advantage that designers can anticipate.
By eliminating the need to look at the display while driving to change the sound or air conditioning, using a knob on a display will further boost user safety.
