These systems and methods describe how to determine the movements of a handheld controller (HHC) in relation to a head mounted display (HMD). The camera is situated in lower levels of the HMD for capturing pictures of the HHC. The images of the HHC can be used to determine the position and orientation of HHC by referring to the HMD. The HMD can also be placed and oriented in real-world settings by using the camera or a different camera. The orientation and location of the HMD as well as the position and orientation of the HHC can be used to switch to the state of an app that is executed on the game cloud.

A head-mounted display (HMD) can be utilized to play games. The HMD is attached to the head of the participant. The player holds the DualShock.TM. controller which is used to play the game. The camera is positioned in a space, such as a TV stand where the player is playing the game. The camera captures images of the participant.

It is within this context that the embodiments described in present disclosure arise.

The disclosure described herein describes techniques and systems that can be utilized to measure the movement of a controller with respect to a head mounted display (HMD) using specific embodiments.

One example describes the system that monitors a hand-held device relative to an HMD. The system comprises a hand-held controller, the HMD and a processing device. The HMD can be placed around the neck of the user. Additionally the HMD is able to display multiple images scenes that contain content generated by an application. A camera is situated in the lower part of the HMD. The camera can capture a perspective that faces downwards towards the HMD. The camera can be set to capture multiple pictures of the hand-held controller. The HMD is linked to the processor for receiving a plurality images of the real-world environment and the plurality images from the hand-held control. From the plurality images of the real-world environment the processing device is able determine the position and the movement of HMD in the real-world. Based on the multitude of images taken by the controller processing device, the device is able to determine the hand-held controller’s position relative the HMD. The processing device is capable of altering a state by execution of an application in response to the movements and positions and changes in the location of the controller. In response to changes in state the HMD is able to update the variety of images that are shown through the HMD.

A method is described in an embodiment of tracking a hand-held control unit in relation to an HMD. This method displays a number of images that contain the content generated by an application. The HMD comes with cameras in the lower area. The camera has an image capture view that is directed downwards from the HMD. The method also includes the capture using the camera several images of the hand-held controller with regards to the HMD. The method is based on receiving a variety of images of the real-world surroundings surrounding the HMD and also the numerous images taken by the hand-held controller. From the many images of the real-world environment, the method also includes the determination of the movement and position of the HMD in the real world. The method includes determining a location of the hand-held controller in relation to the HMD from the plurality of images taken by the controller that is hand-held. Modifying the output of a state through execution of the application based on the movement and position and the changes in the position of the HMD is an additional aspect of the method. Modifying the state of the HMD will also mean that the HMD will update the plurality image scenes.

In a particular embodiment of a computer-readable medium that contains program instructions for tracking the hand-held controller in relation to an HMD is explained. Execution of the instructions by one or more processors of the computer system triggers one or more processors to perform a plurality of operations of the procedure described above.

Hand-held controllers (HHC) can be used as a replacement for the camera in the lower portion of the HMD. This is just one of the many benefits of the described systems and methods. The HHC is more likely to not be visible from the camera’s lower region of the HMD. Also the HMD moves alongside the camera. The camera in the lower portion of the HMD captures HHC movement. An outside-in tracking camera like one that is facing towards the HMD is not able to capture HHC motion.

Are you looking for similar patents? Here are the steps to follow:

1. Create a list of terms for your invention, based on its purpose and composition or use.

Write down a short detailed explanation of your invention. Do not use generic terms like “device”, “process,” or “system”. Consider synonyms for the terms you picked initially. Next, take note of important technical terms as well as keywords.

Use the questions below to help you identify key words or concepts.

  • What’s the goal of this invention? Is it a utilitarian device or an ornamental design?
  • Is the invention a method of creating something or executing some function? Are you referring to an item?
  • What is the composition and function of the invention? What is the physical makeup of the invention?
  • What’s the objective of the invention?
  • What are the terms in the technical field and the keywords used to define the nature of an invention? To find the right terms, refer to a technical dictionary.

2. Utilize these terms to locate relevant Cooperative Patent Classifications on the Classification Text Search Tool. If you’re unable to find the right classification for your invention, look through the class Schemas (class schedules) and then try again. Think about substituting the words you use to describe your invention if you don’t receive any results from your Classification Text Search with synonyms like the ones you used in step 1.

3. Go through the CPC Classification Definition for confirmation of the CPC classification you’ve found. The hyperlink to the CPC classification definition is provided in the event that the title of the chosen classification is a blue square with a “D” on the left. CPC classification definitions can be used to identify the specific classification’s scope, so you are sure to select the most appropriate. Additionally the definitions may include some tips for searching and other information that may be useful for further research.

4. The Patents Full-Text Database and the Image Database allow you to search for patent documents that have the CPC classification. You can look through and narrow down the most relevant patent publications by focusing first on the abstract and drawings representative of.

5. This list of patent publication is the best to examine for connections to your invention. Be sure to read the claims and specification. Contact the applicant as well as the patent examiner for any additional patents.

6. Find patent applications published in the public domain using the CPC classification you selected in Step 3 from the Applications Full-Text and Image Database. The same search strategy is applicable to Step 4. You can narrow the results of your search to find the most relevant patent applications by reading the abstracts and representative drawings on every page. After that, you must review the patent applications that have been published carefully and pay particular attention to the claims as well as other drawings.

7. Find additional US patents by keyword searching in PatFT or AppFT databases, classification search of non-U.S. patents according to below, and searching non-patent literature disclosures of inventions using web search engines. Here are some examples:

  • Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
  • Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
  • Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
