Abstract: A virtual reality system (100) and device for use therein involve an optical detection arrangement (200) configured to detect a light pattern associated with a unique identity, and a tool (300) having a plurality of light-emitting devices (600) engaged therewith. The light-emitting devices (600) are selectively user-actuatable between a plurality of light patterns detectable by the optical detection arrangement (200). The light patterns provide a plurality of unique identities of the tool (300) as detected by the optical detection arrangement (200).

Abstract: A method, a system, and computer program product for managing pay equity cloud-based software applications are provided. A query for compensation data for an employment position associated with a macro-entity is received. The employment position is defined by parameters associated with a micro-entity. The compensation data for similar employment positions associated with the macro-entity is retrieved, from a database and by using the parameters. The compensation data is processed to generate grouped and ranked employment positions. Compensation gaps between the ranked employment positions are determined, by executing a multivariate regression analysis including an analysis of one or more cohorts of employment positions within the ranked employment positions. A recommendation for adjusting compensation associated with one or more employment positions is generated, by using a machine learning model. An instruction to display a notification including the recommendation is provided.
