The embodiments of the disclosure provide a method and system for retrieving querying results, and a computer readable storage medium. The method includes: reading a private data; performing an irreversible transformation on the private data to generate a reference data; transmitting a first query data to a server, wherein the first query data is determined according to the reference data; querying a public database based on the first query data to retrieve a plurality of first querying results; transmitting the plurality of first querying results and first information associated with the plurality of first querying results to the client device; determining a plurality of second querying results among the plurality of first querying results based on the first information; and showing second information associated with the plurality of second querying results.

A posture tracking apparatus and method are provided. The apparatus captures an eye image of a user. The apparatus calculates an eye posture based on the eye image. The apparatus captures a reflected image from the eye image. The apparatus calculates a head posture of the user based on the reflected image and the eye posture.

A synchronization system and a synchronization method of a coordinate system are provided. The synchronization method includes: communicatively connecting a first head-mounted display to a first mobile device, wherein the first mobile device includes a first light source, and the first mobile device and the first head-mounted display correspond to a first coordinate system; outputting a first light based on a first mode by the first light source; identifying the first mobile device according to the first light by a second head-mounted display, wherein the second head-mounted display corresponds to a second coordinate system; and using the first mobile device as a reference point to synchronize the second coordinate system with the first coordinate system by the second head-mounted display.

A tracking system and a tracking method for power saving are disclosed. The tracking method includes: adjusting, by a first mobile device, at least one of first power consumption of a sensor of the first mobile device and second power consumption of a first light source of the first mobile device; executing, by the first mobile device, at least one of the following: obtaining sensed data according to the adjusted first power consumption; and adjusting illumination of the first light source according to the adjusted second power consumption; and tracking, by a second mobile device, the first mobile device according to at least one of the sensed data and the illumination of the first light source.

The present disclosure provides a tracking method and a multi-device system. The multi-device system is operable in a physical environment. The multi-device system includes a host device and a peripheral device. The tracking method includes: by the host device, generating a first pose data of the peripheral device based on an interaction between the host device and the peripheral device; by the peripheral device, receiving a host map of the physical environment established by the host device; by the peripheral device, generating a second pose data of the peripheral device based on the host map; and by the peripheral device, transferring the second pose data to stop the host device generating the first pose data.

Various solutions for enhanced delay status reporting (DSR) in mobile communications are described. An apparatus may receive a configuration from a network node. The configuration may include a remaining time threshold for triggering a DSR procedure for one or more logical channels within a logical channel group (LCG). Then, the apparatus may trigger the DSR procedure based on the remaining time threshold. Responsive to triggering the DSR procedure, the apparatus may transmit a DSR medium access control (MAC) control element (CE) to the network node. The DSR MAC CE may include a plurality of entries of delay status information for the LCG, each of the plurality of entries including a pair of a remaining time field and a buffer size field, and an extension (EXT) field indicative of whether an additional pair of the remaining time field and the buffer size field is present for the LCG in a subsequent entry.

Various solutions for adaptive logical channel prioritization (LCP) in mobile communications are described. An apparatus may select a plurality of logical channels, each configured with a priority, for an uplink (UL) grant, and apply an additional priority for at least one of the logical channels in an event that the at least one of the logical channels carries data with a remaining time of an associated packet data convergence protocol (PDCP) discard timer less than a threshold. Then, the apparatus may allocate resources of the UL grant to one or more of the logical channels, each associated with a positive number of tokens, in a decreasing priority order determined based on the additional priority being applied. The apparatus may further perform a new transmission based on the allocation of the resources of the UL grant.
