Patent number: 9317171Abstract: Described is an approach to gesture interaction that is based on user interface widgets. In order to detect user gestures, the widgets are provided with hotspots that are monitored using a camera for predetermined patterns of occlusion. A hotspot is a region where a user interacts with the widget by making a gesture over it. The user's gesture may be detected without the user physically touching the surface displaying the widget. The aforesaid hotspots are designed to be visually salient and suggestive of the type of gestures that can be received from the user. Described techniques are advantageous in relation to conventional systems, such as systems utilizing finger tracking, in that they can better support complex tasks with repeated user actions. In addition, they provide better perceived affordance than conventional systems that attempt to use widgets that are not designed for gesture input, or in-the-air gesture detection techniques that lack any visual cues.Type: GrantFiled: April 18, 2013Date of Patent: April 19, 2016Assignee: FUJI XEROX CO., LTD.Inventors: Patrick Chiu, Qiong Liu, Maribeth Joy Back, Sven Kratz

Patent number: 9299084Abstract: Systems and methods are disclosed herein for improving customer service. A video feed of a camera viewing a POS queue is analyzed to identify customers and measure customer biometric data.

Patent number: 9141874Abstract: An image of real world is processed to identify blocks as candidates to be recognized. Each block is subdivided into sub-blocks, and each sub-block is traversed to obtain counts, in a group for each sub-block. Each count in the group is either of presence of transitions between intensity values of pixels or of absence of transition between intensity values of pixels. Hence, each pixel in a sub-block contributes to at least one of the counts in each group. The counts in a group for a sub-block are normalized, based at least on a total number of pixels in the sub-block. Vector(s) for each sub-block including such normalized counts may be compared with multiple predetermined vectors of corresponding symbols in a set, using any metric of divergence between probability density functions (e.g. Jensen-Shannon divergence metric). Whichever symbol has a predetermined vector that most closely matches the vector(s) is identified and stored.Type: GrantFiled: March 7, 2013Date of Patent: September 22, 2015Assignee: QUALCOMM IncorporatedInventors: Raj Kumar Krishna Kumar, Pawan Kumar Baheti, Dhananjay Ashok Gore
