Haptic guidance: Advancements, challenges, and future directions in human-computer interaction

Haptic guidance changes how humans interact with computers by using touch-based feedback to support learning, control, and decision-making. This review presents an overview of recent progress in haptic guidance systems, focusing on how different types of feedback, such as force, vibration, and movement, can be combined to create more natural and effective experiences. These technologies are now widely used in fields such as robotic surgery, rehabilitation, virtual and augmented reality, teleoperation, assistive devices, and education. The paper outlines the core components of haptic systems, including sensors, actuators, and control methods, and explains how they work together to simulate the sense of touch. It also explores different feedback strategies and how they help users perform complex tasks more safely and accurately. Despite these advancements, several challenges remain. These include delays in system response, limited portability, high cost, and difficulty adapting to different users. There are also important ethical concerns, such as privacy, accessibility, and over-reliance on technology. The review highlights current trends, such as the use of artificial intelligence, soft materials, and wearable devices, which are helping to make haptic systems smarter, smaller, and more personalized. Future work should focus on making these systems more affordable, inclusive and reliable, especially for long-term and real-world use. With continued progress, haptic guidance has the potential to greatly enhance how people learn, work, and interact across digital and physical environments.
