DISPLAYS
Even small deviations in amplitude, frequency or pulse shape can make sensations feel unnatural, reducing operator confidence and precision. To maintain natural, responsive feedback, haptic systems often rely on closed-loop control, precise waveform shaping and real-time adjustment. These features ensure that each tactile pulse aligns with human expectations, even under varying conditions or in demanding environments.
As digital interfaces replace mechanical controls, this capability is becoming increasingly important. Traditional levers, knobs and switches communicated through movement and resistance; flat touch panels do not. Haptics restore that missing layer of communication, providing users with a physical confirmation of their actions and a clearer sense of how the machine is responding.
In industrial operations, this has immediate benefits. Inputs can be confirmed without relying entirely on visual cues, which helps reduce cognitive load and keeps attention on the task rather than the screen. It can also help improve reaction times and enable operators to perform high-precision actions with increased confidence.
Yet, creating reliable, expressive haptic feedback is still technically challenging without the right expertise. It demands low-latency signal generation, precise actuator control and consistent performance in harsh industrial environments. These requirements can push conventional electronics to their limits, calling for a more specialised approach.
CUSTOM SOLUTIONS
Delivering precise, reliable haptic feedback requires electronics that can generate signals with exact timing, amplitude and frequency, while remaining robust to temperature fluctuations, electrical noise, and continuous operation.
Standard, off-the-shelf components often struggle to meet these demands. This is because they typically rely on multiple discrete chips to perform the necessary functions, which increases latency, complicates circuitry and makes it difficult to integrate haptics into compact, space-constrained panels.
To overcome these limitations, ASICs provide a unique solution. These purpose-built chips consolidate waveform generation, signal conditioning, actuator control and power management onto a single silicon die. Consolidating these critical functions onto a single chip allows ASICs to eliminate inter-chip communication delays and synchronisation issues. Integration ensures that signals can be delivered with millisecond-level precision, keeping amplitude, frequency and pulse shape carefully controlled; while minimising even subtle deviations that could make feedback feel unnatural or inconsistent. It also enables advanced on-chip features. Memory and processing resources can implement sophisticated waveform-shaping algorithms, closed- loop feedback and real-time error compensation.
This allows the system to continuously adjust tactile outputs in response to actuator variation, temperature shifts or electrical interference, without compromising latency or precision.
For operators, the benefits are significant. Consolidated into sleek digital panels, these systems deliver a new level of tactile feedback far beyond the use of mechanical controls, allowing users to confirm inputs directly through touch. This reduces cognitive load, sharpens reaction times and supports more precise, confident operation. By tightly synchronising signal generation, actuation and monitoring, ASICs ensure consistent, reliable performance even in demanding industrial environments with heat, vibration or electrical noise.
ASICs bridge the gap between human intent and machine response, giving digital interfaces a sense of touch that feels natural and immediate. They enable operators to interact with machines confidently, safely and efficiently, even under demanding conditions, transforming technology from a purely visual tool into an extension of human action and perception.
