Manufacturers are therefore developing “smart” switches that provide a similar user experience without mechanical motion. The mechanical switches are cheap and provide tactile feedback, but are subject to wearout after extended use. When designing input controls (e.g., switches and knobs), it's important to provide protection against these contaminants, which can otherwise prove lethal to electronic equipment.Īlthough HMI systems have long employed protection methods such as rubber boots on switches, the constant movement over time renders the seals prone to failure. There's also a large peripheral set, including integrated C66x DSPs, multiple communication options, and a dedicated video-acceleration engine.Īn industrial environment is likely to contain a broad range of chemicals and pollutants, including water, dirt, oil, dust, solvents, and acids. The family includes devices with single or dual ARM Cortex-A15 cores running at 1.5 GHz, with performance as high as 10,500 Dhrystone MIPS.

A scalable family of devices built around a common core can maximize code reuse across applications and shorten development time.įor example, the Sitara AM57x microprocessor family can cover the range of HMI applications. Particular care should be taken to include a realistic estimate of computationally demanding tasks like video processing, and display functions such as 2D or 3D graphics. Knowing the performance requirements is important when choosing an embedded processor for HMI applications. (Source: Texas Instruments) (Click on image to enlarge) A complete HMI includes multiple functional blocks and can demand considerable processing power. Current approaches rely heavily on GUI technology, which coincidently was first demonstrated in 1968, the year of “2001.”įigure 2 shows an HMI ecosystem, which contains multiple functional blocks: an applications processor power management wired and wireless communications and a variety of systems to interact with an operator, such as knobs, switches, a monitor (perhaps with touchscreen capability), and so on.Ģ. A well-designed HMI delivers information that helps users with their decision-making processes.Īn HMI system’s effectiveness is determined by its processing power, ability to render complex images, fast response time to user inputs, and flexibility in handling various levels of operator interactions.
The HMI provides interaction between the operator and the process or equipment being controlled, so it requires two-way communication that goes well beyond an on-off switch and a light. In process control, HMIs connect sensors, actuators, and other equipment on the factory floor to supervisory and control systems. Ranging from simple segmented displays to high-resolution LCD panels, HMIs can be located on the machine, in battery-operated handheld devices, and in centralized control rooms. With controls and information graphically displayed on the screen, the operator can use either a touchscreen or external buttons to control the machinery. An industrial example is a control panel that allows an operator to interact with a machine in a graphical, visual way. HMI provides a means of controlling, monitoring, managing, or visualizing device processes. Goodbye.”Īlthough the human-machine interface (HMI) is becoming more intelligent, this conversation luckily hasn't yet taken place (so far as we know). I'm afraid I can't do that,” followed shortly by “Dave, this conversation can serve no purpose anymore. Unfortunately for Dave, HAL's response was “I'm sorry, Dave.

Those who are of, shall we say, a certain age will recognize the quote in the title, from the iconic 1968 sci-fi movie “2001: A Space Odyssey.” The scene involved an interchange between a human-astronaut Dave Bowman-and a machine-HAL 9000, a sentient computer-using voice interaction (Fig. Is the HAL 9000's human-machine interface (here with its unlucky operator) the future of HMI? Hopefully not.
