The physical constraints of smartwatches limit the range and complexity of tasks that can be completed. Despite interface improvements on smartwatches, the promise of enabling productive work remains largely unrealized. This paper presents <i>WearWrite</i>, a system that enables users to write documents from their smartwatches by leveraging a crowd to help(More)
While most smartphones today have a rich set of sensors that could be used to infer input (<i>.e.g.</i>, accelerometer, gyroscope, microphone), the primary mode of interaction is still limited to the front-facing touchscreen and several physical buttons on the case. To investigate the potential opportunities for interactions supported by built-in sensors,(More)
Wearable and contextually aware technologies have great applicability in task guidance systems. Order picking is the task of collecting items from inventory in a warehouse and sorting them for distribution; this process accounts for about 60% of the total operational costs of these warehouses. Current practice in industry includes paper pick lists and(More)
User identification and differentiation have implications in many application domains, including security, personalization, and co-located multiuser systems. In response, dozens of approaches have been developed, from fingerprint and retinal scans, to hand gestures and RFID tags. In this work, we propose CapAuth, a technique that uses existing, low-level(More)
Visually impaired people can struggle to use everyday appliances with inaccessible control panels. To address this problem, we present ApplianceReader - a system that combines a wearable point-of-view camera with on-demand crowdsourcing and computer vision to make appliance interfaces accessible. ApplianceReader sends photos of appliance interfaces that it(More)
Cucumber (Cucumis satvus L.) seeds were imbibed in distilled water (control) and 10 mg l−1 triadimefon (TDM) for 10 h and then grown in a plant growth chamber with a light/dark temperature of 28/20 °C and a photoperiod of 14 h with a light intensity of 60 µmol m−2 s−1. 14-day-old seedlings were exposed to chilling stress with a light/dark temperature of 6/3(More)
The world is full of physical interfaces that are inaccessible to blind people, from microwaves and information kiosks to thermostats and checkout terminals. Blind people cannot independently use such devices without at least first learning their layout, and usually only after labeling them with sighted assistance. We introduce <i>VizLens</i> - an(More)
Smartwatches are becoming increasingly powerful, but limited input makes completing complex tasks impractical. Our WearWrite system introduces a new paradigm for enabling a watch user to contribute to complex tasks, not through new hardware or input methods, but by directing a crowd to work on their behalf from their wearable device. WearWrite lets authors(More)
Because smartwatches are worn on the wrist, they do not require users to hold the device, leaving at least one hand free to engage in other activities. Unfortunately, this benefit is thwarted by the typical interaction model of smartwatches; for interactions beyond glancing at information or using speech, users must utilize their other hand to manipulate a(More)
Experiments suggest that using head-up displays like Google Glass to support parts picking for distribution results in fewer errors than current processes. Making Glass opaque instead of transparent further improves selection efficiency. The Web extra at http://youtu.be/yUZFaCP6rP4 is a video demonstrating that order picking assisted by head-up display(More)
