Handheld Wireless Display for Head-Mounted Computing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays are limited in providing optimal viewing comfort and functionality, as they require mechanical packaging and styling that can be restrictive, are not easily upgradeable, and lack the ability to interface with various devices for day-to-day tasks, requiring users to carry bulkier computers for accessing information.
Innovation Solution
A handheld, high-resolution microdisplay device with wireless connectivity that allows users to access and control host devices without the need for continuous input, using gestures, voice commands, or external devices, providing a more versatile and lightweight solution for viewing and interacting with data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If head-mounted display is designed with mechanical packaging and styling to mount on user's head, then the display can be positioned on the user's face, but the device becomes restrictive and not easily upgradeable
Solution Approach 1:
The display device is divided into separate functional modules: a display unit, a mounting mechanism, and a support structure. The mounting mechanism is designed as a detachable component that can be easily removed and replaced, allowing the display unit to be upgraded or replaced without discarding the entire device. This segmentation enables flexibility and adaptability while reducing the complexity of the overall mechanical packaging.
Solution Approach 2:
The mounting mechanism incorporates adjustable and reconfigurable components that allow the display to be positioned at different angles and locations on the user's face. The support structure can be dynamically adjusted to accommodate different user needs and preferences, making the device more versatile and easier to upgrade without being constrained by a fixed mechanical design.
2Adaptability or versatility
If prior art head worn displays are designed with fixed functionality, then the display can show images and graphics, but the device cannot interface with other devices for day-to-day tasks
Solution Approach 1:
The display device is designed with universal interface capabilities that allow it to connect with various external devices such as smartphones, tablets, and computers. The device incorporates wireless communication modules and standardized connection interfaces that enable it to function as a secondary display, control interface, or information hub, expanding its functionality beyond just displaying images and graphics.
Solution Approach 2:
The display device acts as an intermediary between the user and other electronic devices. It provides wireless communication capabilities and interface protocols that facilitate interaction with smartphones, tablets, and computers, allowing users to control these devices or access their functionality through the display unit without direct physical connection.
3Ease of operation
If users carry bulkier computers to access information, then they have full functionality, but mobility and convenience are reduced
Solution Approach 1:
The display device extracts and concentrates the essential display and interface functions into a compact, lightweight unit that can be easily carried. By separating the display functionality from the computing functions, the device provides a portable viewing interface that users can carry without needing to bring along larger computers or tablets, improving mobility while maintaining access to information.
Solution Approach 2:
The display device transforms the computing experience from a single large display dimension to a distributed multi-dimensional interface. The compact display unit can be positioned at different locations on the user's body or face, providing access to information in multiple spatial dimensions without requiring a large portable computer, thus improving mobility and convenience.

AI summary
A handheld wireless display device, having at least SVGA-type resolution, includes a wireless interface, such as Bluetooth™, WiFi™, Wimax™, cellular or satellite, to allow the device to utilize a number of different hosts, such as a cell phone, personal computer, media player. The display may be monocular or binocular. Input mechanisms, such as switches, scroll wheels, touch pads, allow selection and navigation of menus, playing media files, setting volume and screen brightness/contrast, activating host remote controls or performing other commands. The device may include MIM diodes, Hall effect sensors, or other position transducers and/or accelerometers to detect lateral movements along and rotational gestures around the X, Y and Z axes as gesture inputs and movement queues. These commands may change pages, scroll up, down or across an enlarged screen image, such as for web browsing. An embedded software driver (e.g., Microsoft Windows SideShow™) permits replicating a high-resolution screen display from a host PC. The device may repeatedly poll the host at intervals for updated content even when the host is powered off, asleep or hibernating, and may return the host to its previous power state.
