Head-Worn Wireless Microdisplay for Compact Multi-Host Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-mounted displays are limited in viewing comfort, functionality, upgradeability, and compatibility with various devices, and users desire lightweight, compact solutions that can access important data without the need for bulky computers.
Innovation Solution
A handheld, high-resolution microdisplay device with wireless connectivity, allowing users to interface with multiple host devices, including laptops and smartphones, using gestures, voice commands, or wireless inputs, and providing SVGA or higher resolution display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of moving object
If a projection type display is attached to a head-mountable support, then a large format display appearance is provided, but the device becomes heavy and complex requiring precise alignment and adjustment mechanisms
Solution Approach 1:
The patent extracts the display function from a complex projection system and integrates it into a compact microdisplay device that can be directly mounted on the user's face. This eliminates the need for separate projection components, alignment mechanisms, and adjustment apparatus, while still providing a large format display appearance through the microdisplay's optical characteristics.
Solution Approach 2:
The microdisplay device serves multiple functions: it provides display output, acts as the user interface, and functions as the mounting mechanism itself. The device integrates what would traditionally require separate components (projection system, eyepiece, support structure, alignment mechanisms) into a single unified unit that automatically positions itself relative to the user's eye.
2Ease of operation
If a microdisplay device is made handheld and wireless, then portability and ease of use are improved, but the device must be lightweight and compact which limits display size
Solution Approach 1:
The patent replaces the mechanical advantage of larger display surfaces with optical characteristics of a microdisplay. By using a microdisplay with specific optical properties (high resolution, appropriate viewing angle) and positioning it close to the user's eye, the device achieves a large format display appearance without requiring a physically large display surface, thus maintaining portability.
3Ease of manufacture
If head-mounted displays are designed with fixed mounting structures, then manufacturing is simplified, but viewing comfort and adaptability for different users are reduced
Solution Approach 1:
The patent incorporates flexible mounting structures that allow the microdisplay to be positioned at different locations on the user's face and adjusted to different orientations. The mounting structure includes flexible elements and adjustable components that enable customization for each user's anatomical variations, while still maintaining a relatively simple overall design that can be manufactured efficiently.

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.
