A new patent from Dell, with the title "SYSTEM AND METHOD FOR HEADSET HAPTIC OR AUDIO CONFIRMATION FEEDBACK FOR GAZE ACTIVATION" (patent number: US20240028110A1), introduces an innovative solution to a common issue faced by users interacting with devices using gaze detection technology. With the increasing use of graphical user interfaces (GUI) and the need for precise selection and control, the accuracy and user experience of gaze tracking systems have become a critical concern. This patent aims to resolve these issues by incorporating haptic and audio feedback through a wireless headset device.
In existing systems, the gaze detection function relies solely on visual feedback presented on the display screen. However, this approach has limitations. Users often encounter delays in knowing whether their gaze has been accurately tracked, mis-selections may occur, and difficulties may arise in navigating the system. The shifting of the user or movement of the user's eyes can contribute to these challenges, making it cumbersome to interact with the gaze tracking system effectively.
Dell's patented solution utilizes a wireless headset device to provide haptic or audio feedback to users, confirming the activation of gaze controls on an information handling system. This system operates in conjunction with a camera, such as a web camera, which captures images of the user and tracks their gaze and actions on the display screen. By integrating haptic or audio cues through the wireless headset device, users receive immediate confirmation of their actions, enhancing their interaction with the device.
The disclosed figures in the patent further illustrate the capabilities of this innovative system. Figure 1 showcases a block diagram of an information handling system coupled with a wireless headset device executing the gaze detection function system. Figure 2 depicts the wireless headset device wirelessly connected to the host information handling system, operating an audio and haptic feedback control system. These diagrams provide a visual representation of how the patented technology functions and its integration into existing devices.
In a real-life scenario, users can benefit from Dell's GazeTracker Headset, which incorporates the patented technology. Imagine a user selecting a specific item from a GUI displayed on a screen. With the GazeTracker Headset, the user's gaze will be accurately detected and confirmed through haptic feedback, such as gentle vibrations on the headset, or audio cues, such as subtle beeps. This immediate confirmation reassures users that their selection has been accurately registered, eliminating any ambiguity in their interaction with the device.
Moreover, the GazeTracker Headset enhances cursor control. In Figure 5A and 5B, we see the wireless headset device providing haptic or audio feedback as users navigate the cursor on the screen, improving their precision and reducing the likelihood of errors.
While this Dell patent promises to address the limitations of existing gaze tracking systems, it's important to note that patents do not guarantee the appearance of a product in the market. However, this innovation presents a potential solution to a pervasive user interaction issue and could significantly enhance the user experience on information handling systems.
P.S. This technology is a patent and its market availability is not yet certain.
