Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Description of Business Immersion Corporation (the "Company", "Immersion", "we" or "us") was incorporated in 1993 in California and reincorporated in Delaware in 1999. We focus on the creation, design, development, and licensing of innovative haptic technologies that allow people to use their sense of touch more fully as they engage with products and experience the digital world around them. We have adopted a business model under which it provides advanced tactile software, related tools, technical assistance designed to help integrate our patented technology into our customers’ products or enhance the functionality of our patented technology to certain customers, and offers licenses to our patented technology to other customers. Impact of COVID-19 The outbreak of a novel strain of coronavirus ("COVID-19") caused governments and public health officials around the world to implementing stringent measures to help control the spread of the virus. In response to the COVID-19 pandemic, we implemented work-from-home and restricted travel policies in the first quarter of 2020, which have remained in place. In April 2020, the Government of Canada announced the Canada Emergency Wage Subsidy (“CEWS”) for Canadian employers whose businesses were affected by the COVID-19 pandemic. The CEWS provides a subsidy of up to 75% of eligible employees’ employment insurable remuneration, subject to certain criteria. We applied for the CEWS to the extent we met the requirements to receive the subsidy. During the six months ended June 30, 2021 we recognized $0.2 million in government subsidies as a reduction to operating expenses in the Condensed Consolidated Statements of Operation and Comprehensive Income (Loss). We did not recognize for any government subsidy during the six months ended June 30, 2022. Principles of Consolidation and Basis of Presentation The accompanying condensed consolidated financial statements include the accounts of Immersion and our wholly-owned subsidiaries. All intercompany accounts, transactions, and balances have been eliminated in consolidation. The accompanying condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for interim financial information and with the instructions for Form 10-Q and Article 10 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all information and footnotes necessary for a complete presentation of the financial position, results of operations, and cash flows, in conformity with U.S. GAAP and should be read in conjunction with our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2021. In the opinion of management, all adjustments consisting of only normal and recurring items necessary for the fair presentation of the financial position and results of operations for the interim periods presented have been included. Use of Estimates The preparation of condensed consolidated financial statements and related disclosures requires management to make estimates and assumptions that affect the reported amounts of the condensed consolidated financial statements. Significant estimates include revenue recognition, fair value of financial instruments, useful lives of property and equipment, valuation of income taxes including uncertain tax provisions, stock-based compensation and long-term deposits for withholding taxes. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. The results of operations for the three and six months ended June 30, 2022 are not necessarily indicative of the results to be expected for the full year. Segment Information We develop, license, and support a wide range of software and IP that more fully engage users’ sense of touch when operating digital devices. We focus on the following target application areas: mobile devices, wearables, consumer, mobile entertainment and other content; console gaming; automotive; medical; and commercial. We manage these application areas in one operating and reporting segment with only one set of management, development, and administrative personnel. Our chief operating decision maker (“CODM”) is the Chief Executive Officer. The CODM approves budgets and allocates resources to and assesses the performance of our business using information about our revenue and operating loss. There is only one segment that is reported to management. Recently Adopted Accounting Pronouncements In November 2021, Financial Accounting Standard Board ("FASB") issued ASU 2021-10, Government Assistance (Topic 832), which requires annual disclosures that increase the transparency of transactions involving government grants, including the types of transactions, the accounting for those transactions, and the effect of those transactions on an entity’s financial statements. This new standard became effective for annual periods beginning after December 15, 2021. We adopted this new guidance in the first quarter of 2022. This adoption did not have material impact on our condensed consolidated financial statements.
