User-Experience with Haptic Feedback Technologies and Text Input in Interactive Multimedia Devices

Abstract

Remote control devices are commonly used for interaction with multimedia equipment and applications (e.g., smart TVs, gaming, etc.). To improve conventional keypad-based technologies, haptic feedback and user input capabilities are being developed for enhancing the UX and providing advanced functionalities in remote control devices. Although the sensation provided by haptic feedback is similar to mechanical push buttons, the former offers much greater flexibility, due to the possibility of dynamically choosing different mechanical effects and associating different functions to each of them. However, selecting the best haptic feedback effects among the wide variety that is currently enabled by recent technologies, remains a challenge for design engineers aiming to optimise the UX. Rich interaction further requires text input capability, which greatly influences the UX. This work is a contribution towards UX evaluation of remote control devices with haptic feedback and text input. A user evaluation study of a wide variety of haptic feedback effects and text input methods is presented, considering different technologies and different number of actuators on a device. The user preferences, given by subjective evaluation scores, demonstrate that haptic feedback has undoubtedly a positive impact on the UX. Moreover, it is also shown that different levels of UX are obtained, according to the technological characteristics of the haptic actuators and how many of them are used on the device.

Development of a Human-Display Interface with Vibrotactile Feedback for Real-World Assistive Applications

“…However, haptic studies on touch screens have mainly focused on modeling the click vibrations that occur at moments of state transition of a button rather than on basic perceptual characteristics [31]. Since Fukumoto and Sugimura [32] first introduced the "active touch(click)" concept, studies have been conducted on the magnitude, duration, and stimulator for vibration signals to implement a significantly realistic haptic feedback of the press-and-release stroke of a virtual button on a touch screen [33][34][35][36][37][38]. These studies have important implications because pressing a button is preferred over using touch screens in vehicles, where visual distraction can be a problem.…”

Usability Tests for Texture Comparison in an Electroadhesion-Based Haptic Device

“…ERM and LRA actuators are commonly applied for the same purposes [6,7], mainly used in smartphones. From study [8], it was concluded that LRA actuators are much more battery efficient than ERM actuators. Piezo actuators have also been recently embedded on the new Windows 11 trackpads, according to Boréas Technologies [9].…”
