20090034794 | Conduct inference apparatus - In a conduct inference process, feature points are extracted from a capture image. The extracted feature points are collated with conduct inference models to select conduct inference models in each of which an accordance ratio between a target vector and a movement vector is within a tolerance. Among the selected conduct inference models, one conduct inference model in which a distance from a relative feature point to a return point is shortest is selected. Then, a specific conduct designated in the selected conduct inference model is tentatively determined as a specific conduct the driver intends to perform. Furthermore, based on the tentatively determined specific conduct, it is determined whether the specific conduct is probable. When it is determined that the specific conduct is probable, an alarm process is executed to output an alarm to the driver. | 02-05-2009 |
20090103815 | Body position detecting apparatus - In a body position detecting apparatus, a controller repeatedly acquires image data that includes an object and an operator in a place where the operator is capable of operating the object. When the controller detects that the operator is in an operating position where the operator operates the object, the controller detects a position of a body part of the operator in the image data and the controller sets the position of the body part to an initial position. The controller detects a position of the body part of the operator in the image data that is acquired after the initial position is set, by detecting a displacement from a position of the body part detected last time and accumulating the displacement to the initial position. | 04-23-2009 |
20100157059 | ACTION ESTIMATING APPARATUS, METHOD FOR ESTIMATING OCCUPANT'S ACTION, AND PROGRAM - A detection unit obtains a position of a feature point of an occupant. A storage unit stores a model of all specific actions in each of physical feature classifications. The model defines a position or a locus of the feature point in each specific action, which an occupant may perform. A determining unit compares an in-action feature point with each model of a specific action, which is being performed, to determine a classification conformity weight indicating a possibility that the occupant belongs to the physical feature classification. An estimating unit compares the position of the feature point with each model to obtain a comparison result and generate a conformity value by incorporating the classification conformity weight into the comparison result. The estimating unit detects an estimated action, which is a specific action corresponding to the model, which has a highest conformity value. | 06-24-2010 |
20100158316 | Action estimating apparatus, method for updating estimation model, and program - A storage unit stores a model defining a position or a locus of a feature point of an occupant in each specific action. An action estimation unit compares the feature point with each of the models to detect an estimated action. A detecting unit detects that a specific action is being performed as a definite action. A first generating unit generates a new definite model corresponding to the definite action by modifying a position or a locus of the feature point according to an in-action feature point when the definite action is being performed. A second generating unit generates a new non-definite model using the in-action feature point according to a correspondence between the feature point in the definite action and the feature point of a non-definite model other than the definite model. An update unit updates the definite action model and the non-definite action model. | 06-24-2010 |
20110187862 | STEERING WHEEL GRIP DETECTION APPARATUS AND PROGRAM PRODUCT - A steering wheel grip detection apparatus is disclosed. The apparatus is configured to: acquire information indicative of actual position of a steering wheel in a vehicle compartment; acquire an image captured by an imaging device; identify position of the steering wheel on the image by applying the actual position of the steering wheel to a prescribed correspondence position relationship between the actual position and the position on the image; identify hand position of a person appearing on the image; and determine whether the steering wheel is gripped, based on whether the hand position on the image is on the position of the steering wheel on the image. | 08-04-2011 |
20110254956 | DRIVING ASSISTANCE APPARATUS - In a hand-free driving warning process for a vehicle, when a grip state of a steering wheel is in a hand-free driving state, and the vehicle is in a travel state stipulated previously, a danger degree is derived based on a position of a vehicle compartment where a non-grip hand exists. In deriving the danger degree, when the non-grip hand is in a high danger position, a high level is set; when the non-grip hand exists in a low danger position, a middle level or a low lever is set. In the low level, any warning is not outputted; in the middle level, a warning is outputted in a sound volume smaller than a usual sound volume; and in the high level, a warning is outputted in the usual sound volume or greater. | 10-20-2011 |
20120147032 | MANIPULATION INFORMATION INPUT APPARATUS - Several images are displayed based on instructions. A map image is displayed first as a base image. A destination setup image is then displayed as a manipulation image. A telephone number input image is then displayed also as a manipulation image. Then, an input of a telephone number of a destination is made to the telephone number input image. When an event occurs in the middle of the input, a present map image is alternatively displayed while the previously displayed images from the map image as a closest displayed base image up to the telephone number input image as an interrupted displayed manipulation image are recorded as an image transition in an image recording portion. When the event disappears, the recorded image transition is displayed from the closest displayed base image up to the interrupted displayed manipulation image, enabling smooth resumption of the interrupted input. | 06-14-2012 |
20130328673 | DRIVING ABILITY REDUCTION DETERMINING APPARATUS - A driving ability reduction determining apparatus comprising a virtual image display portion, an operation portion, a response detection portion and a driving ability determination portion is disclosed. The virtual image display portion emits a determination-usage display image toward a windshield, thereby displaying to the driver the determination-usage display image as a virtual image through the windshield. The operation portion is operated by the driver when the driver visually recognizes the determination-usage display image. The response detection portion detects a response situation of driver's operation of the operation portion in response to display of the determination-usage display image by the virtual image display portion. The driving ability determination portion determines the driving ability reduction of the driver based on a detection result of the response detection portion. | 12-12-2013 |
20140088452 | STRESS EVALUATION APPARATUS, STRESS EVALUATION METHOD AND STRESS EVALUATION PROGRAM - A stress evaluation apparatus, a stress evaluation method, and a program for evaluating stress received by an operator during when an in-vehicle device is operated by an upper limb are provided. The apparatus includes a detection sensor, a calculation process portion and an evaluation portion. The detection sensor detects a muscle potential of a measuring object muscle of the operator. The calculation process portion receives time series information of the muscle potential to calculate strength information. The evaluation portion compares the strength information with an evaluation standard to make an evaluation of stress of the operator. The method includes detecting a muscle potential of a measuring object muscle, receiving time series information of the muscle potential to calculate strength information, and comparing the strength information with an evaluation standard to evaluate stress. A medium storing a computer-executable program that causes a computer to perform the above-described method is provided. | 03-27-2014 |
