Analyzing human motion is important in a number of ways. An athlete constantly needs to evaluate minute details about his or her motion pattern. In physical rehabilitation, the doctor needs to evaluate how well a patient is rehabilitating from injuries. Some systems are being developed in order to identify people only based on their gait. Automatic interpretation of sign language is another area that has received much attention. While all these applications can be considered useful in some sense, the analysis of human motion can also be used for pure entertainment. For example, by filming a sport activity from one view, it is possible to create a 3D reconstruction of this motion, that can be rendered from a view where no camera was originally placed. Such a reconstruction system can be enjoyable for the TV audience. It can also be useful for the computer-game industry. This thesis presents ideas and new methods on how such reconstructions can be obtained. One of the main purposes of this thesis is to identify a number of qualitative constraints that strongly characterizes a certain class of motion. These qualitative constraints provide enough information about the class so that every motion satisfying the constraints will "look nice" and appear, according to a human observer, to belong to the class. Further, the constraints must not be too restrictive; a large variation within the class is necessary. It is shown how such qualitative constraints can be learned automatically from a small set of examples. Another topic that will be addressed concerns analysis of motion in terms of quality assessment as well as classification. It is shown that in many cases, 2D projections of a motion carries almost as much information about the motion as the original 3D representation. It is also shown that single-view reconstruction of 2D data for the purpose of analysis is generally not useful. Using these facts, a prototype of a "virtual coach" that is able to track and analyze image data of human action is developed. Potentials and limitations of such a system are discussed in the the thesis. / QC 20100601

As digitalization becomes more pervasive in our society, healthcare is no exception. That new technology promises life-transforming innovations is perhaps of little doubt, but many of these innovations might never reach the market, for a plethora of reasons – many of which are investigated within this thesis. This thesis seeks to codify both industry best practices and extant literature to create a generic roadmap in the form of a framework usable by entrants to facilitate their entry into the Swedish healthcare market. The paper builds on an interpretivist approach and utilizes interviews with experts from the sector, representing companies in all stages of maturity - in addition to providing a micro-level view via survey responses for a specific audience and company in the form of headache sufferers. The paper finds several key obstacles to tackle for a potential entrant, with the primary ones being understanding the reimbursement system, the role and importance of partnerships and the challenge in finding the right talent. Finally, the paper presents a model to navigate the market entry - and codifies the concept of 'pilot death' - failing to scale to any significant degree after a pilot partnership. / Den ökade digitaliseringen har medfört nya möjligheter, inte minst inom sjukvård. Ny teknologi för med sig många av dessa möjligheter och bland dessa kan det ibland finnas de som medför omfattande ändringar till våra liv. Många av dessa innovationer når dock aldrig marknaden trots att grundidén har potential att förbättra vårdsystemet. En möjlig förklaring är de hinder som kan uppstå när en produkt eller tjänst lanseras. Denna rapport undersöker därför vad industrin anser vara de viktigaste momenten att tänka på under ett marknadsinträde. Rapporten bygger på intervjuer med experter från olika företag inom svensk sjukvård och ger en djupgående inblick, i form av en fallstudie, i ett företag aktivt inom behandling av kronisk huvudvärk. Rapporten identifierar ett antal utmaningar och hinder – där de mest framstående är vikten av att förstå det ersättningssystem som dominerar svensk sjukvård, utmaningen i att hitta rätt kompetens och rollen som samverkan med existerande bolag spelar. Slutligen presenteras en modell för marknadsinträde och konkretiserar konceptet ’pilotdöd’ – där ett bolags lösning inte lyckas nå någon större användning efter ett pilotsamarbete.
